What a god send. Unit was installed by a well know company that has been in business for 50 years, yet they did not ask anything around these settings. The constant dribbling cold breeze when in heat mode is what drove me to start looking for answers & found this. Also the bit of changing the temp sensor to the controller because in summer we were freezing & had the controller temp set to 28c to try tame it. Thank you so much.
Absolute legend. 👍 After spending $15k on a ducted system, you have solved the one gripe I had with it. No longer need to deal with a daft from the return vents.
This has been an incredibly helpful video - thanks! I was going crazy not understanding why my temp would hit the desired level and the whole unit would just keep going.
After fighting with this thermostat for almost a year since installation, you have solved my problems. Thank you! Wish you were local in the US, you'd have a new customer.
Thanks mate, my Daikin ducted systems works a lot better now. No draft air from my 2x return air vents. Sensor set to wall thermostat, rather than the return air vents and manages the room temp and set temp a lot better. Thank you again so much.
Very useful video with a detailed explanation. Good job sir. I was not aware there is an option to turn off the fan after the configured temperature is reached. Now I just can relax in complete silence :)
I found it best to keep fan running during cooling, 22 - 6, during hot weather I found the ducting can warm up in the ceiling space and when the fan turns back I will get a blast of warm air before it cools. Keeping the inside fan running prevents this and having a draft during cooling is also preferrable IMHO.
Hello, I was just wondering what your recommended field setting would be for the fan on a Daikin unit in “cool” mode as the information online is very conflicting. In your video you suggest to set it to 22 6:03 (Fan shuts off when set temperature is reached), would that be your recommended setting to ensure a longer lifespan on the unit. As there are arguments for and against it, some of the information online suggest that having the fan on 22 6:02 in “cool” mode has benefits over having it set to 22 6:03. In your experience what setting ensure longevity of the unit?
Person choose, change it and see if you like it and how the system operates, you can change it back easily. I leave on unit on from the start of summer, if the house is hot the system runs to cook it down, we have had a cool spell in the weather and the system hasn’t needed to come on for the last two days, if the fan was set to run all the time I would find it annoying. Personal choice, you can set 02 as well low low fan speed.
Thank you for your prompt response! Appreciate the information. Would you say one option over another ensures a longer lifespan for the unit? Or one tends to cause more issues in the long term with parts wearing out?
@@Kakashi_San_1989 no, l can’t see one over the other having an impact on life of the unit, the quality of the installation will have the biggest effect on the life of the system than any thing else. Evacuating the system below 500 microns to ensure no oxygen or moisture exists in the refrigerant circuit and just a general quantity insulation. That’s the biggest cause of premature failure of a system. Using cert three in refrigeration air conditioning trade and not a cert 2 installer, one is a 4 year apprenticeship and the others a 2 day course, so many cowboys companies and workers in this industry.
Thank you for the information! Wish you were located in VIC hard to find good honest tradesman like yourself these days! Only wish I stumbled upon your page earlier.
This controller cannot do that. You would need a controller that’s has zone function. Assuming it’s a ducted unit, you would need to have zone motors installed in the ductwork to the room you want to be able to turn off.
I was wondering if I could ask a question about efficient use of this unit over the winter? Currently I leave it on all day/ night set between 18 and 22 degrees Celsius. 18 when I leave the house and in between 20-22 when I get home. Am I using this unit properly or can you advise otherwise? Much appreciated! Thanks
From experience leaving it on is more cost effective as the system is just ticking over and not running at full speed to raise the temp in the space. When my wife started staying home with the newborn I thought the running cost would go through the roof, but it was the same if not cheaper to run and more comfortable.
@@FullyAirconditioned rather than turning it off, what settings would you have during the winter? Would you switch from fan to heating when you are not home? or would you put heating on all day and lower the fan speed when out? - Presuming you can't do this in the scheduling?
@@victoriaweingartner6376 Hi Victoria, Well we have our Daikin set to turn on to 22 degrees at 5.30am , turn down to 16 deg c at 9.00am, (make shore it set to heat because if it’s set to auto it will cool the house to 16 😬). We have good northern facing glass so house gets good free heat from the sun during the day, we make shore the curtains are open during the day. At 3.00 pm the unit turn back on at 22 deg c and runs through to 10.00 pm. At 10pm it turn back down to 16 deg c and run through the night (well the system is on but it doesn’t blow any air as the fan is set to cycle off, on the real cold nights, below 0 deg c it might kick in once , twice, maybe three times during the night. So it’s not set to turn off during winter but when it’s set down to 16 deg c it hardly comes on. That’s how we run ours, if someone is home they can over ride the settings, but next time it passes through a schedule it will change to the set schedule.
Thanks for the informative video! I tried these settings out, and when I changed 22-3-01 to 22-3-03, and changed 22-6-02 to 22-6-03, this seems to have changed something on the compressor - it seems to step through more incremental speeds, and some of these are really quite loud and buzzy, clearly being heard from inside the house. Are these setting supposed to change the compressor settings like this? If I reset back to 22-3-01 and 22-6-02, everything goes back to normal again and the outside compressor is back to normal noise levels (i.e. not being heard from inside the house). My set up is an Australian install of a Daikin 3 phase FDYQN180LB-LY, and the outdoor unit is a RZQ180LY1, all using a BRC1E63 controller. I've tried to look up where I can find the field settings for this unit in case they're just different for this unit, but I'm having no luck at all finding them. Can you help at all please? Thanks in advance!!
The settings are common for this unit, when you change the fan to cycle on and off with the t-stat you will need to set the sensor to the wall controller as it’s factory set to the indoor unit. If the fan cycles off, the indoor sensor is not sensing the room temperature air as there is no Air passing over it, this could be causing a big differential, and when the system starts back up, it realises that the temperature differences is wider than what it was reading, it may need to ramp up to a high-speed or over come the larger temp differential. You should set 20-2-03 sensing from wall controller only when setting the fan to cycle off. When it’s set to fan all ways being on it may be cycling the compressor more frequently at a lessor speed. But you are doing the correct thing, if it’s not how you want it change it back. You could try setting it too 22-6-01 fan set to low low speed in cooling t-stat off and keep it set to indoor unit sensor. This will drop the fan to a very low speed when the t-stat is off but keeps a small amount of air passing over the sensor in the indoor unit. Trial and error, just make a note of what it was set too original and if you’re not happy change it back.
@@FullyAirconditioned Thanks for the quick reply! Yeah, I originally tried that with 20-2-03 set too, and that’s when I encountered the problem. I tried it with 20-2-02 (the original setting) too, but it kept happening. I’ll just try going with low-low fan speed for cooling instead (22-6-03). Thanks again for the help and detailed videos!
No sorry, the Daikin units feld setting can only be accessed by the Daikin controller, when air touch is installed, the people installing it should have connected a Daikin controller to test run it and set all the field settings, if it's set up correctly the temp sensor on the air touch should be the control point for the air touch. you would normally set the sensor in the remote control. There are instructions online at polyaire about the set up of the air touch as there are a few ways that can be configured as well.
After 4 years of trying to figure out my my system was so goofy I finally have an answer! I have 4 air handlers in a ducted system. upstairs would always go colder than set temp and downstairs would never get down to the set temp.
Question, I have also read that when you change the thermistor location to the remote only that you should also make changes of 20-8-2 and 20-5-2. Any input on this? Mine is actually a BRC1E73 controller
Thank you! My parents had this system installed 3 weeks ago and fan has been running "ultra low" after desired temperature was reached since the day it was installed.
Hi, if I wanted a specific room temperature to be monitored which setting would this be? For example the main bedroom I put it on 25 degrees but it goes to 20 degrees when aircon is on, I think this is because the main living room is the temperature recognition but we arnt cooling it therefore thinks he needs to pump it colder? Tips please
Mabe invest in a smart zoning system like the "MyAir zoning system", this can be retrofitted to a Daikin system, it will give you temp control in all zones and the ability to select what sensor is active. You can just leave in automatic and it will set the room with the biggest temp difference from set point as the master to cool that room faster, if the other rooms reach set point the zone will automatically close off stopping the supply of cool air to that room. It's your best bet to give your Daikin more control, you will also have wifi as standard with the myair.
Thank you for the informative video. I followed your instructions and now i cannot access/change the operation mode . Its currently blank and pressing button does not change to COOL,DRY,HEAT,etc. Please advise how can i get this to work again.
This video is about setting up a standard Daikin BRC1E63 wall mounted controller with the standard field settings we would set when connected to a ducted (Australian ducted) unit. We set the fan to cycle with the thermostat and set the to sensor location for wall controller. We also show how to adjust the fan speed settings and explain how the fan should be set up for best efficiency, effectiveness for heating and cooling operation. we show how to get into setting mode for the Daikin wall controller.
Thank you very much for the detailed video. I don’t seem to have the Room Temp option in the Display Item options. Is there a setting to ensure this is available in Display Items? FYI, I have the BRC1E63 with FDYAN125AV1 Indoor unit and RZA125C2V1 Outdoor unit.
@@FullyAirconditioned I only have three options, None, System and Outside Air Temperature. Any ideas why Room Temp is not an option; thought it might be a field settings issue but can’t find a master file that explains every field setting… Really appreciate your help.
@@LChristou-n4j check felid setting 1c - 0 - 02 this allows room temp to be displayed in “detailed settings”. It’s set to this from factory so someone must have changed too 1c -0 - 01, “not displayed”.
@@FullyAirconditionedThank you so much, that worked. Looks like my room temperature is not accurate - reporting 23 when it is closer to 19. I have implemented your other settings so it should be reading the wall unit temp. Any suggestions why this could be inaccurate and are there any fixes you’re aware of? Thanks so much again, really appreciate your time.
Thanks mate. Would all the models have a fan only mode? I ask because the apartment complex I’m moving into is being furnished with a brand new system with the same wall controller but the salesperson has mentioned there is only a heating & cooling mode, though I wasn’t convinced by that since all the videos on much older controllers show at least 3 modes (heat, cool, fan, auto & dry). Also, is the BRC1E63 still the latest model? If not, do the latest controllers have any new features compared to this one? Oh & would there be anything else to know if the apartment setup was a mixture of integrated vent in a bulkhead in living room & a couple of split system units in bedrooms (with their own, zoned controllers)? Thanks.
Should have all setting heat coil set fan auto. Yes current controller. If it’s a VRV system one controller will have all mode options, the rest of the controller will be able to operate in the same mode as the master or in fan mode or off.
Loving Arlo! Good looking pup. Craig, I have a Daikin mini split as a second system in my home to cool the second floor which has all the bedrooms. My indoor unit is a FMDQ24RVJU and the outdoor unit is a RXL24UMVJUA. the. O troller is the Daikin OnePlus. I am in the USA and these systems are fairly new into this American market (from what I am aware of…) I am having a problem with overcooling with this system. Are the field setting tje same as what you have explained here? I am having a hard time finding a document that explain what each setting is. The same for what each mode is. I was wondering g if you could provide a link to where I could go find such document. The installer has not been successful on getting this unit to work properly. It is his first Daikin install 😢 Thanks for your video as you explained some of the settings. Sub’d and I hope to hear from you. Cheers!
Hi, Thanks for the vid. After I set the field settings; Mode 22, 3-3, and 6-3, I expected the fan to not run at set temperature, but it continued to run. Any ideas?
It depends on the indoor unit, the settings I have here are for Australian made ducted indoor units, you could try 21-2-02, or try 50-0-04. If they don’t work just set them back to original. If your in the USA your units are different and I don’t know the settings sorry.
Hey do you know what mode 20-02-04 is? I noticed on mine it has modes 1-2-3 like you show for where to sense the temp. But mine also has a 04 option but I don’t know what that one does.
Hi, thank you for posting this clip, its been a life saver. I only have one question, my room temperature is 21, my set temperature is 20 which I increase to 27. It will run at that and warm the house for half hour or so, then stop and the set temperature is back to 20. How do I keep the 27 permanently displayed as the desired room temperature? Is there another mode number to set?
@@janetcarney953 you have set point auto reset active on your controller, go into menu, energy savings options, then go to energy saving list. Here it will let you know what energy saving are turned on, turn them all off.
I was just think there may be a way, when the timer is uses there is a set temp in the off setting with a heating cooling set point. It’s set up so that if the house gets above 35 degrees the system will come on even if its set to off and in heating I think its about 5 degrees, the heating will come on even if its off at the controller. Both the heating and cooling set points can be adjusted to a higher setting for heating or lower set point for cooling. If you set this up the unit should turn on if the temp in the house drops below the set point, so the heating will start and heat your home at night with out the operation light lit. Haven’t tried it my self but I believe it will work, not to shore of the differential of the system kicking in and out, but you should be able to work this out with a bit of trial and error. Thanks Craig
I have my unit on cool mode and fan speed is auto. Set to is 76F and room is 76F so why does the fan keep blowing air? I applied all the settings in your video for field settings!
Mate you’re a legend will see how I go. Issue I have is that the bedrooms have no power whatsoever but the living room heats up in my apartment. Is there a way you can change the power distribution across the different zones? Followed your instructions so let’s see. Also what does the S symbol mean? I did change the energy saving % is that it?
You only need to change the ones you want, but with the fan cycling off it’s best to set the sensor in the wall controller to active. If it doesn’t work how you want just change it back.
Great video mate, just wondering what the main difference between auto fan speed and the selected speeds and what do you recommend for a ducted. Also I have a Daikin 125 and circular grills which seem to make popping sounds only in heating when the indoor fan runs.
Hi Craig, would you mind telling me why my air con the one you are talking about isn’t working in the bedrooms (main bedroom working perfectly) but everywhere else in the house is? I’ve cleaned filters, changed settings. Just don’t know what else to do. It’s so hot my kids are boiling in the rooms.
If it’s a ducted system and the air flow is not even, you won’t get an even temperature. Most common cause is bad duct design, the length of duct feeding that room is longer than the other ducts or too small for the area. The other reason could be that that actually room has a higher heat load the the other rooms (like big west facing windows)
Thank you so much for this video. I was sent the link in a desperate attempt to change the thermostat reading over to the control unit. If this actually works, I’ll nominate you for the TH-cam channel of the year!!! Just out of curiosity…. The fan speed on mine 23-3 has only three settings (1,2 or 3)
Hi Christian, It depends on the model of the ducted indoor unit and how new it is, with the older units they have a AC fan motor with 3 or 4 speeds (usually only 2 selectable from controller) . With the newer units they have a DC fan motor with 15 fan settings, each fan setting adjust the 3 selectable fan speeds at the controller. Yours may be an older system or it could also be a low static indoor unit that has less speeds. Kind regards Craig
Hi - I'm just clarifying the question I asked three weeks ago - I'm not sure you understood what I was getting at. * I want to run my aircon to heat overnight. * With the current frosty nights the outdoor unit will likely go through several defrost cycles. * Are these recurrent defrosts over several nights going to damage that unit?
Hi Greynomad, Defrost is a process of the heating cycle of the system, No it won't damage the unit. if your running it at a lower temp it wont go into defrost as much.
Can you please explain what the Indoor Unit Status temperature labels are for in this setup menu. For example Th1: 22°C, Th5: 27°C etc... my indoor room temp is saying 27°C but it feels much cooler. Could it be incorrect? I have a BRC1E63 as well
Hi Aidan, It depends on what indoor units its connected to, but on ducted systems Australia th1 is usually the suction air thermistor on the indoor unit, th2 heat exchanger liquid line indoor unit, th3 heat exchanger gas pipe indoor unit, th4 discharge air temp indoor unit, th5 could be wall controller ??, easy way to check is to blow warm in the thermistor and see if it changes.
Hi there! I'm using this controller in my duplex apartment. The vent in the upstairs living room is working just fine. However, the vent downstairs has its own wireless remote and receiver, but only the fan mode is working. When I try to switch it to cooling or heating, the receiver's light just blinks, and nothing happens. Any idea what's going on?
@@HL-ng4bh it’s probably a VRV or multi head system with only one outdoor unit, change the mode at the upstairs unit to the mode you want down stairs. Then check the unit down stairs, it should go into the same mode. The up stairs unit is the master and dictates what mode the system is in, give it a try.
@@FullyAirconditioned Thanks for the tip! I've made sure that both the upstairs and downstairs units are on the same mode, but the downstairs vent still isn’t working. Could this be something to do with the field settings? Looking forward to your further advice. Thanks!
There many different ways, you could use Daikin’s wifi controller (air base) and the mobile app, you could use Daikin’s Reiri or a third party interface like cool automations. There are so many different options todo this.
I tried to set it up as your instructions and the fan is turned off successfully. However, in a few minutes later, the fan is on again, and then in the next few minutes later it is off again. Could you guys please instruct me how to set the fan totally off?
You need to set the temp to sense from only the wall controller, I believe it alternates between the return air and the wall controller, Chang that and see how it goes
@@gvan2807 change it to 20-2-03 that should be sensing from the wall controller, make sure that the wall controller doesn’t have any air from the outlets blowing directly at the controller, this air blowing at the wall controller will cause it to short cycle as well if it’s already sensing from the controller
Would you know why my thermostat keeps switching off after 3 hours (exactly 3). I have no timer on, nothing. Is there a field setting to disconnect the wall motion sensor?? I think my rented house might have a motion sensor that’s why it shuts off
@@isharathore9825 check the energy saving options, sounds like someone has set a push button time for 3 hours operation. Push menu, energy saving options, energy saving list and check that that they are all turned off, that should fix it.
Thank you for posting this information. I'm wondering if there's any way to adjust the fan speed range? Right now even the lowest fan setting is too much.
Yes , but only if 23-6-(1-15) 1 groups the three fan speeds selectable from the controller at the lowest speeds. 15 groupe the three fan speed setting to the highest speeds. If you can only select high and low (medium is skipped) your fan is a AC fan motor, with only the few speeds.
Do you know the setting to adjust the cooling “deadband”? When I have the cooling set to 75. It doesn’t turn on til 78 and doesn’t turn off til 72 (+/-3degrees). I’d like to lower that to only +/-1degree if possible. Thanks!
That’s about 1.5 - 2.0 deg c, think that’s about as tight as you will get it .check in the services settings under “minimum set point differential” change if from 1 to 0 and see how that goes. You could also try 22-2-02 in field settings menu “change over set point differential”. Jut remember to write down what it was set to from factory so you can change it back it it doesn’t work.
Thank you - your explanation of what the codes do was very helpful. I have a Daikin ducted setup which was installed last December. At present we are experiencing some hefty frosts, down to -4. Consequently the house was very cold in the morning and the AC unit was struggling to warm it up, especially since it goes into a defrost cycle. Last night I let it run all night with a setting of 20 degrees. This morning the house was warmer but the AC had still entered a defrost cycle which may have happened several times during the night. Is it safe/sensible to let the unit run overnight in these conditions? Do I run the risk of damaging it?
You can plug in a remote sensor into the return air sensor port on the indoor pc board. Then that sensor can be placed somewhere in the house. You then set the controller to sense the temp from the return air temp sensor. If you wanted to switch from one to the other you would have to do it in settings in the controller. The other way would be to inset all a double pole double throw switch and wire two sensor into it and with the flick of the switch you would change sensing locations. You could install the daikin zone controller it has the ability to have two additional sensors fitted that can be selected from the controller. The problem with the zone controller is that it has a rubbish timer, doesn’t show actual temp, is difficult to set timer and doesn’t have half the stand feature of your current controller.
My brand new ducted slimline premium unit was not cooling the house down in extreme weathers. I just checked the settings and it was set on 5 when it had the option on 15 now its blowing cold air must harder. Why was it set so low is that a daiken thing?
Don’t think so as factory set is 10, if you don’t get enough air across the coil it won’t allow the compressor to fully ramp up. The compressor will only run as fast as it’s needed, with low air flow, only so much gas can evaporate off, (changing from a liquid to a vapour) the speed of the compressor is slowed down so that liquid gas doesn’t flood back to the compressor and damage it.
i have three master and two slave VRV systems with 21 indoor units, I have to connect these meters to cool master integration module to access the units in the application. Could you help me how to set up the address for each unit to integrate with cool master module? Is it from the main unit or individual addressing
Go into set up menu ( push and hold return button 5sec) there should be an “group address” in the menu, then scroll down to group address hit enter, then set the group address for that to indoor units, 1-00 will be the 1st unit then 1-01 is the 2nd unit and so on, press enter to save. You need to do this at each indoor units controller. You will probably need the cool master conected at the outdoor unit connections that say “to outdoor unit” all the outdoor unit will need to be daisy chained, Q1 Q2, to outdoor unit, then to the cool master controller.
The unit has detected a fault and has shut down, heck the code and make a note of it, do a power reset, turn it off for 5min then back on, run the unit. If the fault comes back call a Daikin’s service tech
@@FullyAirconditioned if I’ve changed mode 22 - 6 for the fan to turn off when the temp is reached, I’d like to be able to look at the display and know when the fan(and compressor) is currently running vs when it’s not (due to reaching the temp)
@@cyssoK ok I understand, no it doesn’t have this function from the wall controller. You can get a pc board that connects to the indoor unit, it will give you a closed / open contact when the compressor cycle. You can then wire into that contact and output like a light. That’s the only way to do this.
@@FullyAirconditioned thank you for your response!! Too complicated for me. Do you know if this control panel can be replaced with a Nest? Wouldn’t the nest show me this info?
@@cyssoK no, nest is very basic relay on off logic, it switches relays to turn on and off compressor, fan and reverse valve. The Daikin’s units are not simple relay logic, they have micro computer communication between the wall controller, indoor unit and outdoor unit.
This is brilliant. Thanks for such a clear explanation. Our Daikin unit is about 10 years old we have a BRC24Z4 type controller that you cover in another video. Are the settings the same as in this video when you access them? I am trying to work out how to adjust controller so that the fan doesn’t blow cold air for 5 minutes when we first turn the unit on before it starts blowing warm air. Is there a “pre heat” type setting?
If your unit is 10 years old then the fan in the indoor unit is a ac fan motor, this fan only has a few speeds and there is only about 5%~10% different in air flow. When the unit starts up it will warm the indoor unit coil to about 42 deg before it turn no the fan, but the compressor is an inverter and it will take about 10 minutes to reach full speed (full heat output). This different in time is the cool air you are feeling. With the newer units the fan is a dc fan motor that has many speeds, ranging in speed from 5%~100%. The fan comes on slowly and continues to speed up as the coil increases in temperature, the end result is less cool air blowing at start up. With the brc24z4 best to set it to cycle fan off in heating and cooling, if you leave as factory set the fan will stay on all the time unless you have the fan in auto. But in auto fan it will sample the air (turn on the fan every 5 minutes for two minutes) so the return air sensor can take an air temp reading.
@@FullyAirconditioned Thanks for replying so soon! Our problem is the unit starts blowing air as soon as you turn it on. It’s also throwing a U2 message and we’ve been quoted $2200 for a new circuit board install but that’s another story!
OK, set our fan to auto low. Turned it on. Nothing happened for five minutes then warm air started blowing. And no U2 error code! (Until now Ive had to turn unit of and on outside to boot it up without U2) Running like a charm. Magic! Not confident yet about going into the tech menu as you demonstrate to cycle off in heating (code 3 from memory from your video). Thanks again, your videos are excellent at explaining complex settings in a user-friendly way.
Hi there, I keep on getting a message on the screen about filter needing to be cleaned. I clean it but message is still there. Can I get rid of the message? Is there a way? Apart from that aircon works fine.
The air-conditioner doesn’t know that you’ve cleaned the filter. The filter sign is just a timed reminder that comes up after certain period of time on this controller. To clear it you’ve got to push and hold the clear button, that resets the timer and then after 1250 hours will come up again as a reminder. It doesn’t actually know that you’ve cleaned the filter or if the filter dirty.
@FullyAirconditioned ok so basically when that "time to clean filter" or similar appears...go and clean filter and then reset the filter timer - then that message should disappear? So really the filter should only be cleaned when the clean filter message appears?
@@AbsolutelyEverybody1 personally I would clean the filter at a minimum every 6 months, but it really depends on how dirty the environment the system is installed in, it may need doing more frequently than this. You can never have a to clean filter, the cleaner the filter the more efficient the system operates.
@FullyAirconditioned oh really...every 6 months? I read somewhere clean filter every 6 to 8 weeks? Also on my filter there is fluff stuck there and I can't get it out, used water to squirt it out - didn't work. I then tried the blower - didn't work. What I mean by fluff..well it's hard to explain...sort of like dust but fluffy stuff. But apart from the fluff there doesn't appear to be any dust on filter. I might have to pick the fluff out which might take a while.
Another question - thx for your answers so far. I've seen several videos explaining how to set the system to take it's operating temperatures from the controller or the the return air or alternating between the two. But no-one explains why Daikin have the different settings or which one is the best to use. Can you explain which one is best to use and why?
Depends on the insulation application, for a office that’s need to meet the standard for introduced outside air (a conditioned office space requires 1lt/sec of outside air per m2 of floor area). The indoor fan need to run all the time to draw that air in, regardless if it heating or cooling, so measuring from the return air is more accurate. In a home this is not necessary and cycling the fan completely off to stop drafts is best. If the sensor in the return air is active (air inlet of indoor unit) and the fan is not running it’s not actually measuring the room temperature. On a cold but sunny day with a ducted system installed in the roof, the roof cavity may be quite pleasant 22 degrees, but in the house it’s only 18 degrees, if the controller was set to 21 heating, it would not turn on. So it is best to set the controller to look at the wall sensor for control for this application.
Hi, can you please help? I have an extra panel next to the control panel unit which has recently gone to a blank screen and I can't do anything with it. No buttons, controls or anything. I can't see any options in the main panels menus that link to this panel. If I could post a pic, I would. It is a smaller panel, did displelay the room options etc but could work out how to use it then it just went dark screen. Any help is appreciated. TIA.
Nice video! My MSX36 inverter always seems to run at full speed (loud) even with one FDMQ calling for 1 degree change. Any ideas why this could be? Thanks!
The fan at full speed or the heating cooling capacity?? If it’s the fan then it depends on the fam motor type. Ac fan motors are limited to a few speeds with not a lot of difference. A dc fan motor can have many fan speeds over a very wide range.
You should be able to connect a 2nd controller, one will be the master and one will be a slave controller. The 2nd controller can be a wireless remote controller. The wireless remote has a receiver and the actual wireless remote. The receiver is wired back to the indoor unit just like the wall controller and is surface mounted on the plasterboard wall or ceiling. The remote is IR, and only work “line of sight” to the receiver, like a tv remote, it doesn’t work if it’s not pointed at the tv’s receiver. Think it’s a BRC1E62.
Thank you so much for this useful video. My system doesn't show outside temperature, any idea why? Should i activate some field setting to display outdoor temp?
@@aidaobrien5357 we don’t have that controller here in Australia, after having a quick look on line I believe the setting I have set won’t all work, below is a link cdn.daikincloud.io/PIM/Assets/Documents/AG-BRC1e73-field-settings.pdf
Hello! Can you help me with field settings for a cassette type indoor unit, daikin fcag71aveb. I can't make the fan rotate with more than 590rpms. Thank you!
Do you know if you can change the temp reading on the airbase system? On the app it reads one temp which I believe is from return air but on wall u have the room temp Pretty annoying daikin airbase won't allow this can't have a proper room reading
I recently shifted to an apartment where daikin brc1e63 system is installed. I changed the settings following your video. Also, I have set fan speed to auto and set the heat (this is heat not auto node) to 18 degree as it is winters where I am staying, cool temperature is set to 27 degrees, am I setting it correctly? I am totally new to this. Please advise for any corrections in the settings I have done. Regards
If it gets below 18 it should start heating and above 27 start cooling, in-between the two remodel it should do nothing (dead zone). I do find 18 a little too cool tho for heating but whatever you find comfortable.
Hey do you know how to set the cycle on and cycle off duration? When i turn it on, it will stay on for about 2 hours, is there any way i can reduce this to about 30 minutes before it automatically switches off?
should be in the energy saving options list, download the manual for full instructions, but i believe you can change the run on time. kind regards craig
Don’t know sorry, it’s not a model controller available in Australia. The controller is just access to the indoor units pc board, depending on what type of fan and what sensors are installed in the indoor unit will depend on what can be configured. But most setting are very similar, if you can’t change anything, or the No doesn’t exist then it’s not available on the model unit the controller is connected too. Before you change anything make sure you note down what was set from factory before you change it, that way if it doesn’t work you can change it back.
@@FullyAirconditioned thanks for the quick reply mate. Will give it a shot 👌🏻 it’s for an office building. It has loads of these controllers dotted around the floors controlling areas but the installers are saying the control sensors are in the ceiling at the FCU. I always thought the controller had the control sensor so will try it out. Thanks again
Great video, I have a BRC1E62 main controller and was wondering if I can use a BRC1E63 as a sub controller only to switch the unit on and off from another room. cheers
@@FullyAirconditioned thanks for the fast response, I thought the BRC1E63 replaced the BRC1E62. I wired them as a main and sub and Error U5 came up on both controllers. Disconnected the BRC1E63 and all's back to normal.
Hi there, I have one of these controllers, connected to a compact ceiling cassette. My observation is the system never works hard enough when I have it set to FAN AUTO mode. By that I mean it really struggles to reach the set temperature because it rarely shifts itself up beyond the lowest/quietest fan speed/power level. Is there some way in the field settings to make it more keen to shift into a 'higher gear' when in FAN AUTO mode; thus working a bit harder overall? I guess what I'm trying to say is I'd like the system overall to be more enthusiastic about ramping itself up so it can get to the set temperature faster. I had hoped your advice in this video with regard to changing the max fan speed would help, but it seems that playing with this particular field setting isn't available in my setup (I presume this is because I have a ceiling cassette and not a ducted unit).
Hi, With the cassette systems there some field settings that can be set like high ceilings, this off sets the control temperature to compensate for high ceilings. Also there is a different code to make the sensor active in the wired remote control. See attached link drive.google.com/drive/folders/1KHh8K8Bq4G3KYqpdkkU7a4jQAMLbkU36
@@FullyAirconditioned Thankyou for this; much appreciated. It looks like you have the one key document I couldn't find anywhere on the internet! [I came close - after several hours of searching - I found a BRC1E53 installer manual; which talks about adjusting "high air outlet velocity" for different height ceilings - via the same 23-0 setting.] I will have a play with the height settings and see if I can get any useful improvement to my system. As for the making-the-controller-sensor-active setting being different; I just checked my system and it looks like it is already set to use the controller sensor already. Can I ask one more question? Does my particular setup offer any corresponding field settings for the turning-off-indoor-fan-when-thermostat-is-satisfied options that you go through in your video? Many thanks!
@FullyAirconditioned hi, I have this exact question but for a ducted sky air system! Doesn't seem enthusiastic to ramp up as described above while in auto fan speed. Any suggestions?
I'm definitely going to look into making some of these changes. I'm actually chacing info on chaning the settings for the defrost. I'm having terribles with the outside unit freezing up and staying like that until I am forced to get a bucket of hot water.
This won’t help defrost, check out my video on defrost to see if your unit is operating in the same manner. Biggest problem with excessive defrost is under sized system.
@@FullyAirconditioned I will check it out. I only seem to have issues when it drops below zero. Once it freezes up it seems struggle to defrost. It doesn't help that the unit is in a dark cold area behind the house that hardly sees the light of day.
Hi thanks for the video. My wall controller can only be controlled from one master bedroom and not the other rooms. Is there any way to change the settings so each room can be controlled individually?
We have a ducted system with bedroom and living room zones. There is the master control panel in the living space and a slave/sub control panel in the upstairs hallway, with the return air duct in the same upstairs hallway. Does the control panel thermistor only read the downstairs main control panel (when the field settings are changed)? Does it make more sense to use the return air temp in this case?
When sensing from the wall controller when you have a master controller and a slave controller, the sensor will only look at the master controller. The 2nd controller is a slave controller just mimics what happening on the other controller and give you the ability to adjust settings from both controllers.
Very very helpful!! Thank you so much! One more question- The AC is too noisy in one of the bedroom but good in the others. I set the fan speed at 5 and also tried several speeds but didn't help. Is this a normal situation or if there's anything wrong with my AC?
How long is a pice of string, there could be many factors into why it’s noise, air flow, short duct, 1st duct / closet duct to the indoor unit, restricted air flow, too much air flow 🤷♂️. But one thing is that it’s only that outlet, so it would be something different with just that particular duct. Check to see what difference are and maybe that will point you in the right direction.
Hi, Yes but it won’t operate any zones, and if there is a remote temp sensor you won’t able to connect that as well. Why do you want to replace (the crazy-hard to set timers) 😬
@@FullyAirconditioned thanks for the response. The display on my BRC24Z8 controller is scrambled and it makes it difficult to use as I’m unable to read what’s displayed. Was wondering what my options were.
Thanks for the video ,very helpfull. bu my question is i thought that the fan speed can be adjust in mode 23 but in #7 not in number 6 sir cause 7 is factory set. just correct me if i am wrong. tnx
Hi Johnny, As long as I have been doing Daikin about (28 years its been 23-6) with D/C fan motors its 1-15 speed settings and with the old A/C indoor fan motors its was 01 standard static, 02 high static and 03 is for low static. The adjustable speed selections were only available the fan motor was manufactured with multiply speeds, some only have two settings. And this is for Australian ducted models. Thanks
@@FullyAirconditioned ok sir thank you for the enlightenment. i always stand myself for correction specially from people who is better than me or well experienced than me well appreciated Sir. thank u
@@johnnyroxannebautista2063 I could find and settings for #7, #7 setting are there but Daikin has not listed what they do, some times they do have settings that can be set but are like Secret squirrel stuff and not published.
@@FullyAirconditioned hello sir thank you and i admit i'm wrong cause i tried to do it in 23-6 and the fan speed increases. but if i wish to bring it back to the original set up sir? what im gonna do?
Thanks for your video. I have just had two australian systems installed. The installer was adjusting mode 10 and 12 to do the same in your video. Have these settings changed since your video in 2020? Thank you.
Hi Shaun, Good question, No they haven’t changed, codes starting with 1, ie 10 and 12 allow you to change the setting, and codes starting with 2, ie 20 and 22 are where you can view the current setting. With old controllers (about 10-20 years) you had to set the settings in the code starting with 1 and view the current settings in the codes starting with 2. You can now adjust the settings in both 1 or 2, but can only view current setting in codes starting with 2. Hopefully this is not confusing. Thanks Craig
Hey there. Just got a Daikin heat pump installed (FDYA125AV1 indoor unit) and found this video. Of course I jumped in and changed all the settings (apart from the fan speed), then I read that indoor units vary and I may have messed up some setting (didn’t make a note of what I changed from). I did ask the sales person about the this and said it looked ok but he wasn’t sure about Mode 22-3 fan turning off when thermostat shuts off heat. Here comes the question. Why can’t I find online a list of Field Service setting for a particular indoor unit. Protected IP from Daikin? Maybe thanks.
Hi Aaron, It’s actually in the indoor units install manual, has all the setting their, what’s set from factory and setting that can be changed. Factory set to 22.3.01 (low low fan on thermostat off), 22.3.02 is (set speed on the controller) and 22.3.03 (fan off when thermostat off) Kind regards Craig hewitt
The filter requires to be reset on the controller. Do you have a video or steps to restore the system as it is turning off after 10 mins as this message I believe is stopping it from functioning . Two Bulkhead in wall units connect to the compressor.
Filter will not stop the system from operating, the filter is purely a timed function, it’s a reminder and it won’t stop The unit from operating. There is a reset for the filter, if you go into the menu you should find it there. The biggest reason the system could be turning on after 10 minutes is there could be a fault or you may have one of the energy efficiency setting set. So if you go into your main menu, check energy efficiency and just have a look at all the potential settings and make sure that they’re all set to off, that’s what I’ll be checking first.
I believe your units are the same as Australian 🇦🇺 unit. Actually I just looked at a Daikin ducted brochure on the NZ 🇳🇿Daikin web site and they have the same model No’s. 👍🏻 Australian made indoor units and outdoor from the Daikin Thailand factory.
There is a link in the video for the list of faults and what the fault means. I have copied this from the repair manual. E2 ＞ Description Faulty BP unit (Junction box) PCB. Recommended Actions For Model Type All VRVIII / VRVIII-Q - Earth leakage detection if internal (factory) earth leakage device fitted. High pressure sensor or switch may be faulty/ open circuit at "power up". Ensure any unused HP switch sockets on a replacment VRV control PCB have had the bridging jumper inserted (X3A and/or X4A).
Hi. Thanks for videos. I’m new this industry. Working with daikin units Las to weeks since snow and cold started mostly issue is gas leak error. U0-02 error code.what I can do for this error. I don’t think all this AC got gas leak must be something with cold weather. Also any way I can reset error code on the remote control. Thanks
If the Daikin system comes up with U0 in out experience its usually correct in that the refrigerant is low and you have a leak. You need to leak test, find and repair the leak, pull a vacuum below 500 microns and hold for 30min to prove the leak has been repaired. Then charge by weight the correct refrigerant charge into the system, you can not top up it will cause more problems. Repair it correctly the 1st time and it wont give you problems.
There is no calibration, where is it sensing the temp from, you can check this by breathing on the sensor on the wall controller, it the display temp go up it’s measuring from the wall controller, it it doesn’t, it’s measuring from the return air sensor. You can change it and see what one works best for you. The temp reading is just a point if you feel to cold just turn it up or if you feel to hot just turn it down, doesn’t really matter if it not 100% accurate, it just a point in the temp scale.
Hi Craig, the for the video. I set 22-06-03 for the compressor and fan to disable when the temp is reached however in cooling I have a set point of 23degrees and room temp of 22degrees. I have also changed the setting to read the controller temp. Any tips?
Make sure 20-2-03 is set, also check c1-1-02 is set. Some models will all ways have some influence from the return air sensor. The only way around this is to install a remote sensor. You unplug the return thermistor, plug in the same plug on the pc board a remote sensor. You then install wall mounted sensor next to the wall controller. That’s the only way around this, there are a number of different sensors available from DAIKIN depending on the indoor model, if you get the wrong one, you can always cut the plug off the existing sensor and join the cables to the wall mounted sensor.
Great video mate. I set up to your specs for the summer months running AC mode, worked wonderfully. Switching to heat mode for our winter months, it seems I have some tin canning going on in start up and shut down. Any insight would be greatly appreciated.
can a Daikin master controller show which room is being heated up and does it also have a history of this by any chance? This is in a 14 rooms place that are all controlled by one master controller but that have individual controllers of their own. Many thanks
I don’t think so, not as standard. If it a VRV system, there is a way of working out usage for charging the user for there use, but this would have needed to be an option when installing the system, possibly could be retrofitted.
@@FullyAirconditioned Thank you so much for replying so promptly. It is in fact a VRV IV system. There are 14 rooms plus a large room that has units on the ceiling whereas the individual rooms have 1 unit on the ceiling. Each room has an individual controller but the master controller is located in one room. Che units outside look like big refrigerators. could they cost as much as £200 to heat up one of these rooms (400SqFt room with high sealing) for only 1 month with a max use of 2 hours per day?
I've made the changes as per your video (thanks) but it doesn't appear like the fan/condenser turns off once it reaches the set temperature. I set to 24 (cold) and timer of 2hours and it ends up getting too cold and can see the room temp is below (23) the set temperature. What could i be missing?
@@FullyAirconditioned I haven’t tried turning the temp up, I’ll give that a go. Am I assuming correctly if the auto off timer still has time left only the air/condenser turns off and the power light still stays on? Definitely set the codes to -03 to turn off for hot and cold.
The fact you just introduced your dog rather than start again gives off huge BDE vibes. Arlo wanted his 15 minutes he knows whats up.
What a god send. Unit was installed by a well know company that has been in business for 50 years, yet they did not ask anything around these settings. The constant dribbling cold breeze when in heat mode is what drove me to start looking for answers & found this. Also the bit of changing the temp sensor to the controller because in summer we were freezing & had the controller temp set to 28c to try tame it. Thank you so much.
No problem 👍🏻
Absolute legend. 👍
After spending $15k on a ducted system, you have solved the one gripe I had with it.
No longer need to deal with a daft from the return vents.
Simple fix that the installer should be setting at commision of the system.
I have question, at night on my thermostat it shows standby and doest not heat.
This has been an incredibly helpful video - thanks! I was going crazy not understanding why my temp would hit the desired level and the whole unit would just keep going.
Wow thank you! Way to make this system come alive! 4 bedroom house with like 7 vents. Turned it up to 10. What a major difference all this info made
After fighting with this thermostat for almost a year since installation, you have solved my problems. Thank you! Wish you were local in the US, you'd have a new customer.
Thanks mate 👍🏻
Thanks mate, my Daikin ducted systems works a lot better now. No draft air from my 2x return air vents. Sensor set to wall thermostat, rather than the return air vents and manages the room temp and set temp a lot better. Thank you again so much.
Glad I could help
Extremely helpful and also relevant for the BRC1E73 model
Very useful video with a detailed explanation. Good job sir. I was not aware there is an option to turn off the fan after the configured temperature is reached. Now I just can relax in complete silence :)
Thank you so much!!! You solved a problem I had been suffering through for years!! Thank you
I found it best to keep fan running during cooling, 22 - 6, during hot weather I found the ducting can warm up in the ceiling space and when the fan turns back I will get a blast of warm air before it cools. Keeping the inside fan running prevents this and having a draft during cooling is also preferrable IMHO.
Awesome video, you are a legend. Short, sweet and straight to the point. Immense thanks.
Hello,
I was just wondering what your recommended field setting would be for the fan on a Daikin unit in “cool” mode as the information online is very conflicting. In your video you suggest to set it to 22 6:03 (Fan shuts off when set temperature is reached), would that be your recommended setting to ensure a longer lifespan on the unit. As there are arguments for and against it, some of the information online suggest that having the fan on 22 6:02 in “cool” mode has benefits over having it set to 22 6:03. In your experience what setting ensure longevity of the unit?
Person choose, change it and see if you like it and how the system operates, you can change it back easily. I leave on unit on from the start of summer, if the house is hot the system runs to cook it down, we have had a cool spell in the weather and the system hasn’t needed to come on for the last two days, if the fan was set to run all the time I would find it annoying. Personal choice, you can set 02 as well low low fan speed.
Thank you for your prompt response! Appreciate the information. Would you say one option over another ensures a longer lifespan for the unit? Or one tends to cause more issues in the long term with parts wearing out?
@@Kakashi_San_1989 no, l can’t see one over the other having an impact on life of the unit, the quality of the installation will have the biggest effect on the life of the system than any thing else. Evacuating the system below 500 microns to ensure no oxygen or moisture exists in the refrigerant circuit and just a general quantity insulation. That’s the biggest cause of premature failure of a system. Using cert three in refrigeration air conditioning trade and not a cert 2 installer, one is a 4 year apprenticeship and the others a 2 day course, so many cowboys companies and workers in this industry.
Thank you for the information! Wish you were located in VIC hard to find good honest tradesman like yourself these days!

Thank you, you are a life saver. So clear and easy instructions 🙏
My brand new units were under heating and changing the mode 20 2 to 03 fixed it. Thank you for this video!
Thanks you for the thanks
Thank you. I just want to know how to turn off the AC only in some rooms while it’s on in the other areas at the same time?
This controller cannot do that. You would need a controller that’s has zone function. Assuming it’s a ducted unit, you would need to have zone motors installed in the ductwork to the room you want to be able to turn off.
I was wondering if I could ask a question about efficient use of this unit over the winter? Currently I leave it on all day/ night set between 18 and 22 degrees Celsius. 18 when I leave the house and in between 20-22 when I get home. Am I using this unit properly or can you advise otherwise? Much appreciated! Thanks
From experience leaving it on is more cost effective as the system is just ticking over and not running at full speed to raise the temp in the space. When my wife started staying home with the newborn I thought the running cost would go through the roof, but it was the same if not cheaper to run and more comfortable.
@@FullyAirconditioned rather than turning it off, what settings would you have during the winter? Would you switch from fan to heating when you are not home? or would you put heating on all day and lower the fan speed when out? - Presuming you can't do this in the scheduling?
@@victoriaweingartner6376
Hi Victoria,
Well we have our Daikin set to turn on to 22 degrees at 5.30am , turn down to 16 deg c at 9.00am, (make shore it set to heat because if it’s set to auto it will cool the house to 16 😬). We have good northern facing glass so house gets good free heat from the sun during the day, we make shore the curtains are open during the day. At 3.00 pm the unit turn back on at 22 deg c and runs through to 10.00 pm. At 10pm it turn back down to 16 deg c and run through the night (well the system is on but it doesn’t blow any air as the fan is set to cycle off, on the real cold nights, below 0 deg c it might kick in once , twice, maybe three times during the night. So it’s not set to turn off during winter but when it’s set down to 16 deg c it hardly comes on.
That’s how we run ours, if someone is home they can over ride the settings, but next time it passes through a schedule it will change to the set schedule.
Thanks for the informative video! I tried these settings out, and when I changed 22-3-01 to 22-3-03, and changed 22-6-02 to 22-6-03, this seems to have changed something on the compressor - it seems to step through more incremental speeds, and some of these are really quite loud and buzzy, clearly being heard from inside the house. Are these setting supposed to change the compressor settings like this? If I reset back to 22-3-01 and 22-6-02, everything goes back to normal again and the outside compressor is back to normal noise levels (i.e. not being heard from inside the house).
My set up is an Australian install of a Daikin 3 phase FDYQN180LB-LY, and the outdoor unit is a RZQ180LY1, all using a BRC1E63 controller. I've tried to look up where I can find the field settings for this unit in case they're just different for this unit, but I'm having no luck at all finding them. Can you help at all please? Thanks in advance!!
The settings are common for this unit, when you change the fan to cycle on and off with the t-stat you will need to set the sensor to the wall controller as it’s factory set to the indoor unit. If the fan cycles off, the indoor sensor is not sensing the room temperature air as there is no Air passing over it, this could be causing a big differential, and when the system starts back up, it realises that the temperature differences is wider than what it was reading, it may need to ramp up to a high-speed or over come the larger temp differential. You should set 20-2-03 sensing from wall controller only when setting the fan to cycle off. When it’s set to fan all ways being on it may be cycling the compressor more frequently at a lessor speed. But you are doing the correct thing, if it’s not how you want it change it back. You could try setting it too 22-6-01 fan set to low low speed in cooling t-stat off and keep it set to indoor unit sensor. This will drop the fan to a very low speed when the t-stat is off but keeps a small amount of air passing over the sensor in the indoor unit. Trial and error, just make a note of what it was set too original and if you’re not happy change it back.
@@FullyAirconditioned Thanks for the quick reply! Yeah, I originally tried that with 20-2-03 set too, and that’s when I encountered the problem. I tried it with 20-2-02 (the original setting) too, but it kept happening. I’ll just try going with low-low fan speed for cooling instead (22-6-03).
Thanks again for the help and detailed videos!
I only have a AirTouch connected to my daikin unit. Is there a way to program the daikin unit with the AirTouch
No sorry, the Daikin units feld setting can only be accessed by the Daikin controller, when air touch is installed, the people installing it should have connected a Daikin controller to test run it and set all the field settings, if it's set up correctly the temp sensor on the air touch should be the control point for the air touch. you would normally set the sensor in the remote control. There are instructions online at polyaire about the set up of the air touch as there are a few ways that can be configured as well.
Thank you so much for this video!
This is very helpful, thank you so much !
After 4 years of trying to figure out my my system was so goofy I finally have an answer! I have 4 air handlers in a ducted system. upstairs would always go colder than set temp and downstairs would never get down to the set temp.
Question, I have also read that when you change the thermistor location to the remote only that you should also make changes of 20-8-2 and 20-5-2. Any input on this? Mine is actually a BRC1E73 controller
Thank you! My parents had this system installed 3 weeks ago and fan has been running "ultra low" after desired temperature was reached since the day it was installed.

Hi, if I wanted a specific room temperature to be monitored which setting would this be? For example the main bedroom I put it on 25 degrees but it goes to 20 degrees when aircon is on, I think this is because the main living room is the temperature recognition but we arnt cooling it therefore thinks he needs to pump it colder? Tips please
Mabe invest in a smart zoning system like the "MyAir zoning system", this can be retrofitted to a Daikin system, it will give you temp control in all zones and the ability to select what sensor is active. You can just leave in automatic and it will set the room with the biggest temp difference from set point as the master to cool that room faster, if the other rooms reach set point the zone will automatically close off stopping the supply of cool air to that room. It's your best bet to give your Daikin more control, you will also have wifi as standard with the myair.
Thank you for the informative video. I followed your instructions and now i cannot access/change the operation mode . Its currently blank and pressing button does not change to COOL,DRY,HEAT,etc. Please advise how can i get this to work again.
This video is about setting up a standard Daikin BRC1E63 wall mounted controller with the standard field settings we would set when connected to a ducted (Australian ducted) unit. We set the fan to cycle with the thermostat and set the to sensor location for wall controller.

Thanks mate. Would all the models have a fan only mode? I ask because the apartment complex I’m moving into is being furnished with a brand new system with the same wall controller but the salesperson has mentioned there is only a heating & cooling mode, though I wasn’t convinced by that since all the videos on much older controllers show at least 3 modes (heat, cool, fan, auto & dry).
Also, is the BRC1E63 still the latest model? If not, do the latest controllers have any new features compared to this one?
Oh & would there be anything else to know if the apartment setup was a mixture of integrated vent in a bulkhead in living room & a couple of split system units in bedrooms (with their own, zoned controllers)?
Thanks.
Should have all setting heat coil set fan auto. Yes current controller. If it’s a VRV system one controller will have all mode options, the rest of the controller will be able to operate in the same mode as the master or in fan mode or off.

It depends on the indoor unit, the settings I have here are for Australian made ducted indoor units, you could try 21-2-02, or try 50-0-04. If they don’t work just set them back to original. If your in the USA your units are different and I don’t know the settings sorry.
Hey do you know what mode 20-02-04 is? I noticed on mine it has modes 1-2-3 like you show for where to sense the temp. But mine also has a 04 option but I don’t know what that one does.
Hi, thank you for posting this clip, its been a life saver. I only have one question, my room temperature is 21, my set temperature is 20 which I increase to 27. It will run at that and warm the house for half hour or so, then stop and the set temperature is back to 20. How do I keep the 27 permanently displayed as the desired room temperature? Is there another mode number to set?
@@janetcarney953 you have set point auto reset active on your controller, go into menu, energy savings options, then go to energy saving list. Here it will let you know what energy saving are turned on, turn them all off.
Thank you so much! We have this unit and want to know if there is a “night mode” because that power light is so bright at night time
Sorry I don’t think it has this function
I was just think there may be a way, when the timer is uses there is a set temp in the off setting with a heating cooling set point. It’s set up so that if the house gets above 35 degrees the system will come on even if its set to off and in heating I think its about 5 degrees, the heating will come on even if its off at the controller. Both the heating and cooling set points can be adjusted to a higher setting for heating or lower set point for cooling. If you set this up the unit should turn on if the temp in the house drops below the set point, so the heating will start and heat your home at night with out the operation light lit. Haven’t tried it my self but I believe it will work, not to shore of the differential of the system kicking in and out, but you should be able to work this out with a bit of trial and error.
Thanks Craig
I have my unit on cool mode and fan speed is auto. Set to is 76F and room is 76F so why does the fan keep blowing air? I applied all the settings in your video for field settings!
Very usefull more than ppl who install the unit for me
YOU A LEGEND
Mate you’re a legend will see how I go. Issue I have is that the bedrooms have no power whatsoever but the living room heats up in my apartment. Is there a way you can change the power distribution across the different zones?
Followed your instructions so let’s see. Also what does the S symbol mean? I did change the energy saving % is that it?
Hi, do all the field settings have to be the same as in this video in order for this to work ?
You only need to change the ones you want, but with the fan cycling off it’s best to set the sensor in the wall controller to active. If it doesn’t work how you want just change it back.
Great video mate, just wondering what the main difference between auto fan speed and the selected speeds and what do you recommend for a ducted. Also I have a Daikin 125 and circular grills which seem to make popping sounds only in heating when the indoor fan runs.
Hi Craig, would you mind telling me why my air con the one you are talking about isn’t working in the bedrooms (main bedroom working perfectly) but everywhere else in the house is?
I’ve cleaned filters, changed settings. Just don’t know what else to do. It’s so hot my kids are boiling in the rooms.
If it’s a ducted system and the air flow is not even, you won’t get an even temperature. Most common cause is bad duct design, the length of duct feeding that room is longer than the other ducts or too small for the area. The other reason could be that that actually room has a higher heat load the the other rooms (like big west facing windows)
Thank you very much helpful advice
Thank you so much for this video. I was sent the link in a desperate attempt to change the thermostat reading over to the control unit.
If this actually works, I’ll nominate you for the TH-cam channel of the year!!!
Just out of curiosity…. The fan speed on mine 23-3 has only three settings (1,2 or 3)
Hi Christian,
It depends on the model of the ducted indoor unit and how new it is, with the older units they have a AC fan motor with 3 or 4 speeds (usually only 2 selectable from controller) . With the newer units they have a DC fan motor with 15 fan settings, each fan setting adjust the 3 selectable fan speeds at the controller. Yours may be an older system or it could also be a low static indoor unit that has less speeds.
Kind regards
Craig
Hi - I'm just clarifying the question I asked three weeks ago - I'm not sure you understood what I was getting at.
* I want to run my aircon to heat overnight.
* With the current frosty nights the outdoor unit will likely go through several defrost cycles.
* Are these recurrent defrosts over several nights going to damage that unit?
Hi Greynomad,
Defrost is a process of the heating cycle of the system, No it won't damage the unit. if your running it at a lower temp it wont go into defrost as much.
@@FullyAirconditioned Thx for that - very reassuring
Can you please explain what the Indoor Unit Status temperature labels are for in this setup menu. For example Th1: 22°C, Th5: 27°C etc... my indoor room temp is saying 27°C but it feels much cooler. Could it be incorrect? I have a BRC1E63 as well
Hi Aidan,
It depends on what indoor units its connected to, but on ducted systems Australia th1 is usually the suction air thermistor on the indoor unit, th2 heat exchanger liquid line indoor unit, th3 heat exchanger gas pipe indoor unit, th4 discharge air temp indoor unit, th5 could be wall controller ??, easy way to check is to blow warm in the thermistor and see if it changes.
Hi there! I'm using this controller in my duplex apartment. The vent in the upstairs living room is working just fine. However, the vent downstairs has its own wireless remote and receiver, but only the fan mode is working. When I try to switch it to cooling or heating, the receiver's light just blinks, and nothing happens. Any idea what's going on?
@@HL-ng4bh it’s probably a VRV or multi head system with only one outdoor unit, change the mode at the upstairs unit to the mode you want down stairs. Then check the unit down stairs, it should go into the same mode. The up stairs unit is the master and dictates what mode the system is in, give it a try.
@@FullyAirconditioned Thanks for the tip! I've made sure that both the upstairs and downstairs units are on the same mode, but the downstairs vent still isn’t working. Could this be something to do with the field settings? Looking forward to your further advice. Thanks!
Hello
I just want to know can this unit be controlled via
Smart home device
If so what are the available devices that will help to accommodate it
There many different ways, you could use Daikin’s wifi controller (air base) and the mobile app, you could use Daikin’s Reiri or a third party interface like cool automations. There are so many different options todo this.
I tried to set it up as your instructions and the fan is turned off successfully. However, in a few minutes later, the fan is on again, and then in the next few minutes later it is off again. Could you guys please instruct me how to set the fan totally off?
You need to set the temp to sense from only the wall controller, I believe it alternates between the return air and the wall controller, Chang that and see how it goes
Could you please instruct me to do that?@@FullyAirconditioned
@@gvan2807 change it to 20-2-03 that should be sensing from the wall controller, make sure that the wall controller doesn’t have any air from the outlets blowing directly at the controller, this air blowing at the wall controller will cause it to short cycle as well if it’s already sensing from the controller
Would you know why my thermostat keeps switching off after 3 hours (exactly 3). I have no timer on, nothing. Is there a field setting to disconnect the wall motion sensor?? I think my rented house might have a motion sensor that’s why it shuts off
@@isharathore9825 check the energy saving options, sounds like someone has set a push button time for 3 hours operation. Push menu, energy saving options, energy saving list and check that that they are all turned off, that should fix it.
Thank you for posting this information. I'm wondering if there's any way to adjust the fan speed range? Right now even the lowest fan setting is too much.
Yes , but only if 23-6-(1-15) 1 groups the three fan speeds selectable from the controller at the lowest speeds. 15 groupe the three fan speed setting to the highest speeds. If you can only select high and low (medium is skipped) your fan is a AC fan motor, with only the few speeds.
life saver! thank you sir!
Do you know the setting to adjust the cooling “deadband”? When I have the cooling set to 75. It doesn’t turn on til 78 and doesn’t turn off til 72 (+/-3degrees). I’d like to lower that to only +/-1degree if possible.
Thanks!
That’s about 1.5 - 2.0 deg c, think that’s about as tight as you will get it .check in the services settings under “minimum set point differential” change if from 1 to 0 and see how that goes. You could also try 22-2-02 in field settings menu “change over set point differential”. Jut remember to write down what it was set to from factory so you can change it back it it doesn’t work.

Thank you - your explanation of what the codes do was very helpful.
I have a Daikin ducted setup which was installed last December. At present we are experiencing some hefty frosts, down to -4. Consequently the house was very cold in the morning and the AC unit was struggling to warm it up, especially since it goes into a defrost cycle.
Last night I let it run all night with a setting of 20 degrees. This morning the house was warmer but the AC had still entered a defrost cycle which may have happened several times during the night.
Is it safe/sensible to let the unit run overnight in these conditions? Do I run the risk of damaging it?
It’s fine to let them run, design to do so. Improving your insulation (heat loss) will help system and reduce running cost.
Is it possible to have an external or second temperature sensor with this controller? We also have an airbase
You can plug in a remote sensor into the return air sensor port on the indoor pc board. Then that sensor can be placed somewhere in the house. You then set the controller to sense the temp from the return air temp sensor. If you wanted to switch from one to the other you would have to do it in settings in the controller. The other way would be to inset all a double pole double throw switch and wire two sensor into it and with the flick of the switch you would change sensing locations. You could install the daikin zone controller it has the ability to have two additional sensors fitted that can be selected from the controller. The problem with the zone controller is that it has a rubbish timer, doesn’t show actual temp, is difficult to set timer and doesn’t have half the stand feature of your current controller.
My brand new ducted slimline premium unit was not cooling the house down in extreme weathers. I just checked the settings and it was set on 5 when it had the option on 15 now its blowing cold air must harder. Why was it set so low is that a daiken thing?
Don’t think so as factory set is 10, if you don’t get enough air across the coil it won’t allow the compressor to fully ramp up. The compressor will only run as fast as it’s needed, with low air flow, only so much gas can evaporate off, (changing from a liquid to a vapour) the speed of the compressor is slowed down so that liquid gas doesn’t flood back to the compressor and damage it.
Will this be the same settings for a cassette for fan cycling off? This code is not in the installation manual, cheers.
Probably not, cassette unit is different and has different setting’s
i have three master and two slave VRV systems with 21 indoor units, I have to connect these meters to cool master integration module to access the units in the application.
Could you help me how to set up the address for each unit to integrate with cool master module? Is it from the main unit or individual addressing
Go into set up menu ( push and hold return button 5sec) there should be an “group address” in the menu, then scroll down to group address hit enter, then set the group address for that to indoor units, 1-00 will be the 1st unit then 1-01 is the 2nd unit and so on, press enter to save. You need to do this at each indoor units controller. You will probably need the cool master conected at the outdoor unit connections that say “to outdoor unit” all the outdoor unit will need to be daisy chained, Q1 Q2, to outdoor unit, then to the cool master controller.
What does a green blinking light mean on the wall controller?
The unit has detected a fault and has shut down, heck the code and make a note of it, do a power reset, turn it off for 5min then back on, run the unit. If the fault comes back call a Daikin’s service tech
Can I get the display to show when the fan is on vs when it’s not? Is there a setting for that?
Sorry I am not sure what you mean??
@@FullyAirconditioned if I’ve changed mode 22 - 6 for the fan to turn off when the temp is reached, I’d like to be able to look at the display and know when the fan(and compressor) is currently running vs when it’s not (due to reaching the temp)
@@cyssoK ok I understand, no it doesn’t have this function from the wall controller. You can get a pc board that connects to the indoor unit, it will give you a closed / open contact when the compressor cycle. You can then wire into that contact and output like a light. That’s the only way to do this.
@@FullyAirconditioned thank you for your response!! Too complicated for me. Do you know if this control panel can be replaced with a Nest? Wouldn’t the nest show me this info?
@@cyssoK no, nest is very basic relay on off logic, it switches relays to turn on and off compressor, fan and reverse valve. The Daikin’s units are not simple relay logic, they have micro computer communication between the wall controller, indoor unit and outdoor unit.
This is brilliant. Thanks for such a clear explanation.
Our Daikin unit is about 10 years old we have a BRC24Z4 type controller that you cover in another video. Are the settings the same as in this video when you access them? I am trying to work out how to adjust controller so that the fan doesn’t blow cold air for 5 minutes when we first turn the unit on before it starts blowing warm air. Is there a “pre heat” type setting?
If your unit is 10 years old then the fan in the indoor unit is a ac fan motor, this fan only has a few speeds and there is only about 5%~10% different in air flow. When the unit starts up it will warm the indoor unit coil to about 42 deg before it turn no the fan, but the compressor is an inverter and it will take about 10 minutes to reach full speed (full heat output). This different in time is the cool air you are feeling. With the newer units the fan is a dc fan motor that has many speeds, ranging in speed from 5%~100%. The fan comes on slowly and continues to speed up as the coil increases in temperature, the end result is less cool air blowing at start up. With the brc24z4 best to set it to cycle fan off in heating and cooling, if you leave as factory set the fan will stay on all the time unless you have the fan in auto. But in auto fan it will sample the air (turn on the fan every 5 minutes for two minutes) so the return air sensor can take an air temp reading.
@@FullyAirconditioned Thanks for replying so soon! Our problem is the unit starts blowing air as soon as you turn it on. It’s also throwing a U2 message and we’ve been quoted $2200 for a new circuit board install but that’s another story!
OK, set our fan to auto low. Turned it on. Nothing happened for five minutes then warm air started blowing. And no U2 error code! (Until now Ive had to turn unit of and on outside to boot it up without U2) Running like a charm. Magic!
Not confident yet about going into the tech menu as you demonstrate to cycle off in heating (code 3 from memory from your video). Thanks again, your videos are excellent at explaining complex settings in a user-friendly way.
Hi there, I keep on getting a message on the screen about filter needing to be cleaned. I clean it but message is still there. Can I get rid of the message? Is there a way? Apart from that aircon works fine.
The air-conditioner doesn’t know that you’ve cleaned the filter. The filter sign is just a timed reminder that comes up after certain period of time on this controller. To clear it you’ve got to push and hold the clear button, that resets the timer and then after 1250 hours will come up again as a reminder. It doesn’t actually know that you’ve cleaned the filter or if the filter dirty.
@FullyAirconditioned ok so basically when that "time to clean filter" or similar appears...go and clean filter and then reset the filter timer - then that message should disappear? So really the filter should only be cleaned when the clean filter message appears?
@@AbsolutelyEverybody1 personally I would clean the filter at a minimum every 6 months, but it really depends on how dirty the environment the system is installed in, it may need doing more frequently than this. You can never have a to clean filter, the cleaner the filter the more efficient the system operates.
@FullyAirconditioned oh really...every 6 months? I read somewhere clean filter every 6 to 8 weeks? Also on my filter there is fluff stuck there and I can't get it out, used water to squirt it out - didn't work. I then tried the blower - didn't work. What I mean by fluff..well it's hard to explain...sort of like dust but fluffy stuff. But apart from the fluff there doesn't appear to be any dust on filter. I might have to pick the fluff out which might take a while.
Another question - thx for your answers so far.
I've seen several videos explaining how to set the system to take it's operating temperatures from the controller or the the return air or alternating between the two. But no-one explains why Daikin have the different settings or which one is the best to use. Can you explain which one is best to use and why?
Depends on the insulation application, for a office that’s need to meet the standard for introduced outside air (a conditioned office space requires 1lt/sec of outside air per m2 of floor area). The indoor fan need to run all the time to draw that air in, regardless if it heating or cooling, so measuring from the return air is more accurate. In a home this is not necessary and cycling the fan completely off to stop drafts is best. If the sensor in the return air is active (air inlet of indoor unit) and the fan is not running it’s not actually measuring the room temperature. On a cold but sunny day with a ducted system installed in the roof, the roof cavity may be quite pleasant 22 degrees, but in the house it’s only 18 degrees, if the controller was set to 21 heating, it would not turn on. So it is best to set the controller to look at the wall sensor for control for this application.
@@FullyAirconditioned Thx for that
@@FullyAirconditioned great answer…very helpful

I really don’t know, could be for zones, some type of zone controller 🤷♂️
Nice video! My MSX36 inverter always seems to run at full speed (loud) even with one FDMQ calling for 1 degree change. Any ideas why this could be? Thanks!
The fan at full speed or the heating cooling capacity?? If it’s the fan then it depends on the fam motor type. Ac fan motors are limited to a few speeds with not a lot of difference. A dc fan motor can have many fan speeds over a very wide range.
Can I use a wireless remote with this? Trying to make this smart within my smart home ecosystem
You should be able to connect a 2nd controller, one will be the master and one will be a slave controller. The 2nd controller can be a wireless remote controller. The wireless remote has a receiver and the actual wireless remote. The receiver is wired back to the indoor unit just like the wall controller and is surface mounted on the plasterboard wall or ceiling. The remote is IR, and only work “line of sight” to the receiver, like a tv remote, it doesn’t work if it’s not pointed at the tv’s receiver. Think it’s a BRC1E62.
Thank you so much for this useful video. My system doesn't show outside temperature, any idea why? Should i activate some field setting to display outdoor temp?

Don’t know sorry, it’s not a model controller available in Australia. The controller is just access to the indoor units pc board, depending on what type of fan and what sensors are installed in the indoor unit will depend on what can be configured. But most setting are very similar, if you can’t change anything, or the No doesn’t exist then it’s not available on the model unit the controller is connected too. Before you change anything make sure you note down what was set from factory before you change it, that way if it doesn’t work you can change it back.

Hi there, I have one of these controllers, connected to a compact ceiling cassette. My observation is the system never works hard enough when I have it set to FAN AUTO mode. By that I mean it really struggles to reach the set temperature because it rarely shifts itself up beyond the lowest/quietest fan speed/power level. Is there some way in the field settings to make it more keen to shift into a 'higher gear' when in FAN AUTO mode; thus working a bit harder overall? I guess what I'm trying to say is I'd like the system overall to be more enthusiastic about ramping itself up so it can get to the set temperature faster. I had hoped your advice in this video with regard to changing the max fan speed would help, but it seems that playing with this particular field setting isn't available in my setup (I presume this is because I have a ceiling cassette and not a ducted unit).
Hi,
With the cassette systems there some field settings that can be set like high ceilings, this off sets the control temperature to compensate for
high ceilings. Also there is a different code to make the sensor active in the wired remote control. See attached link drive.google.com/drive/folders/1KHh8K8Bq4G3KYqpdkkU7a4jQAMLbkU36
@@FullyAirconditioned Thankyou for this; much appreciated. It looks like you have the one key document I couldn't find anywhere on the internet!

As for the making-the-controller-sensor-active setting being different; I just checked my system and it looks like it is already set to use the controller sensor already. Can I ask one more question? Does my particular setup offer any corresponding field settings for the turning-off-indoor-fan-when-thermostat-is-satisfied options that you go through in your video? Many thanks!

Hi thanks for the video. My wall controller can only be controlled from one master bedroom and not the other rooms. Is there any way to change the settings so each room can be controlled individually?
You have multi able controllers ?? Some of the controllers don’t have heating and cooling on them to chose from ably the one in the bedroom??
We have a ducted system with bedroom and living room zones. There is the master control panel in the living space and a slave/sub control panel in the upstairs hallway, with the return air duct in the same upstairs hallway. Does the control panel thermistor only read the downstairs main control panel (when the field settings are changed)? Does it make more sense to use the return air temp in this case?
When sensing from the wall controller when you have a master controller and a slave controller, the sensor will only look at the master controller. The 2nd controller is a slave controller just mimics what happening on the other controller and give you the ability to adjust settings from both controllers.
Super helpful video. Thanks
Very very helpful!! Thank you so much!
One more question-
The AC is too noisy in one of the bedroom but good in the others. I set the fan speed at 5 and also tried several speeds but didn't help. Is this a normal situation or if there's anything wrong with my AC?
How long is a pice of string, there could be many factors into why it’s noise, air flow, short duct, 1st duct / closet duct to the indoor unit, restricted air flow, too much air flow 🤷♂️. But one thing is that it’s only that outlet, so it would be something different with just that particular duct. Check to see what difference are and maybe that will point you in the right direction.

Just one question...the power button need to be on or off? Just at the top right hand corner beside that big circle?
Best if it’s off 👍🏻
Thanks for your video. I have just had two australian systems installed. The installer was adjusting mode 10 and 12 to do the same in your video. Have these settings changed since your video in 2020? Thank you.
Hi Shaun,
Good question, No they haven’t changed, codes starting with 1, ie 10 and 12 allow you to change the setting, and codes starting with 2, ie 20 and 22 are where you can view the current setting. With old controllers (about 10-20 years) you had to set the settings in the code starting with 1 and view the current settings in the codes starting with 2. You can now adjust the settings in both 1 or 2, but can only view current setting in codes starting with 2. Hopefully this is not confusing.
Thanks Craig
Thanks Craig. Is there any chance of getting a copy of the code settings posted for all to see.
Regards Shaun
@@shaun4338 yep will give it a go
Hey there. Just got a Daikin heat pump installed (FDYA125AV1 indoor unit) and found this video. Of course I jumped in and changed all the settings (apart from the fan speed), then I read that indoor units vary and I may have messed up some setting (didn’t make a note of what I changed from). I did ask the sales person about the this and said it looked ok but he wasn’t sure about Mode 22-3 fan turning off when thermostat shuts off heat. Here comes the question. Why can’t I find online a list of Field Service setting for a particular indoor unit. Protected IP from Daikin? Maybe thanks.
Hi Aaron,
It’s actually in the indoor units install manual, has all the setting their, what’s set from factory and setting that can be changed.
Factory set to 22.3.01 (low low fan on thermostat off),
22.3.02 is (set speed on the controller) and
22.3.03 (fan off when thermostat off)
Kind regards

The filter requires to be reset on the controller. Do you have a video or steps to restore the system as it is turning off after 10 mins as this message I believe is stopping it from functioning . Two Bulkhead in wall units connect to the compressor.
Filter will not stop the system from operating, the filter is purely a timed function, it’s a reminder and it won’t stop The unit from operating. There is a reset for the filter, if you go into the menu you should find it there. The biggest reason the system could be turning on after 10 minutes is there could be a fault or you may have one of the energy efficiency setting set. So if you go into your main menu, check energy efficiency and just have a look at all the potential settings and make sure that they’re all set to off, that’s what I’ll be checking first.
Hi there - do you have recommendations for NZ settings?
I believe your units are the same as Australian 🇦🇺 unit. Actually I just looked at a Daikin ducted brochure on the NZ 🇳🇿Daikin web site and they have the same model No’s. 👍🏻 Australian made indoor units and outdoor from the Daikin Thailand factory.
Ok cheers - so fully ducted system and same controller, recommend the settings as per your video?
Hi there, question: what do I if an “E2” error message shows?
There is a link in the video for the list of faults and what the fault means. I have copied this from the repair manual.
E2

Hi. Thanks for videos. I’m new this industry. Working with daikin units Las to weeks since snow and cold started mostly issue is gas leak error. U0-02 error code.what I can do for this error. I don’t think all this AC got gas leak must be something with cold weather. Also any way I can reset error code on the remote control. Thanks
If the Daikin system comes up with U0 in out experience its usually correct in that the refrigerant is low and you have a leak. You need to leak test, find and repair the leak, pull a vacuum below 500 microns and hold for 30min to prove the leak has been repaired. Then charge by weight the correct refrigerant charge into the system, you can not top up it will cause more problems. Repair it correctly the 1st time and it wont give you problems.
Sir how to increase the sensitivity of the gas leak sensor?
I know you can get a gas leak sensor but I have never fitted one or had to set one up, so Soto don’t know.
How do you re-calibrate the temperature I feel my temp is way off from what the thermostat is reading
There is no calibration, where is it sensing the temp from, you can check this by breathing on the sensor on the wall controller, it the display temp go up it’s measuring from the wall controller, it it doesn’t, it’s measuring from the return air sensor. You can change it and see what one works best for you. The temp reading is just a point if you feel to cold just turn it up or if you feel to hot just turn it down, doesn’t really matter if it not 100% accurate, it just a point in the temp scale.
Hi Craig, the for the video. I set 22-06-03 for the compressor and fan to disable when the temp is reached however in cooling I have a set point of 23degrees and room temp of 22degrees. I have also changed the setting to read the controller temp. Any tips?
Make sure 20-2-03 is set, also check c1-1-02 is set. Some models will all ways have some influence from the return air sensor. The only way around this is to install a remote sensor. You unplug the return thermistor, plug in the same plug on the pc board a remote sensor. You then install wall mounted sensor next to the wall controller. That’s the only way around this, there are a number of different sensors available from DAIKIN depending on the indoor model, if you get the wrong one, you can always cut the plug off the existing sensor and join the cables to the wall mounted sensor.
Thank you very much for your explanations¡
Good info, can these keep temperature constant for heating? Instead of dropping 1-2 degrees then coming on?
This setting will keep the temp more accurately at the wall controller location, apposed to the sensor in the indoor unit.
Great video mate. I set up to your specs for the summer months running AC mode, worked wonderfully. Switching to heat mode for our winter months, it seems I have some tin canning going on in start up and shut down. Any insight would be greatly appreciated.
whats it doing
can a Daikin master controller show which room is being heated up and does it also have a history of this by any chance? This is in a 14 rooms place that are all controlled by one master controller but that have individual controllers of their own.
Many thanks
I don’t think so, not as standard. If it a VRV system, there is a way of working out usage for charging the user for there use, but this would have needed to be an option when installing the system, possibly could be retrofitted.
@@FullyAirconditioned Thank you so much for replying so promptly. It is in fact a VRV IV system. There are 14 rooms plus a large room that has units on the ceiling whereas the individual rooms have 1 unit on the ceiling. Each room has an individual controller but the master controller is located in one room. Che units outside look like big refrigerators. could they cost as much as £200 to heat up one of these rooms (400SqFt room with high sealing) for only 1 month with a max use of 2 hours per day?
Cute dog, definitely makes the video
I've made the changes as per your video (thanks) but it doesn't appear like the fan/condenser turns off once it reaches the set temperature. I set to 24 (cold) and timer of 2hours and it ends up getting too cold and can see the room temp is below (23) the set temperature. What could i be missing?
When you turn the temp up dose it turn off, adjust it up till it turn off, what have you set all the codes or just the fan to cycle ??
@@FullyAirconditioned I haven’t tried turning the temp up, I’ll give that a go. Am I assuming correctly if the auto off timer still has time left only the air/condenser turns off and the power light still stays on? Definitely set the codes to -03 to turn off for hot and cold.
