I am sure you get this all the time, John but your video literally made my night. Such a wonderful, slow, easy to understand tutorial is exactly what I needed, and Honeywell was no help!
You’re a hero!!
This video just saved me from hassle time. The electric company have been working on outages in the area. My electricity was actually cut off and back on 37 times this morning, between 9 and 1:30 p.m. My alarm company texted me each time my wifi and alarm base would go off. So, that's how I got the count. I had used a utube video once before to set my thermostat. So, I remembered to check back here to reset it, because it had went back to the factory setting! These video's makes a 70 year old woman not feel so helpless! Thank you again! 👍🏼 ❤
"Save" the link to a YT personal folder category. That way it'll be at your fingertips.😁
A lot of heating contractors and companies are using this thermostat now. It is confusing trying to follow the instruction manual but this video REALLY HELPS on making easier to figure out. Thanks for sharing!!
Finally I found somebody who will go through the setup since I have no directions thank you
All the other videos just want to tell you how to program the thermostat that's pretty much common sense

great video !! Honeywell should tell buyers to watch this video instead of trying to read the user manual
I don’t even know where mine is err where my dads is he set it
That's why it's called the Pro Series. Mainly for HVAC pros that need it. Home Depot sells simpler models.
I had no clue how to operate. This is so helpful. THANKS FOR POSTING IT
I hate this thermostat so bad
what seems to be your issue?
I hate it too 😭
Me too. Cannot program. Does not say following schedule top left.
We have been miserable all freaking day long my battery died I freaking replaced it took the schedule off I did everything every single video said do STUPID thing still will not come on
@@AngiezTurnsame thing is going on with me right now. And it’s 103 outside!
Thank you so much for being so thorough and explaining this thermostat in Laymans terms. We moved into a new home and the previous owner had it on a crazy schedule. Thank you for clarifying you are the best.!
Thanks. This helped my reset my thermostat when it stopped working. It’s negative degrees here so this video was a life saver 🥶
Thank you sr, I was about to replace this damn nightmare of a thermostat!
My heating technician had difficulty programming the two T4 thermostats installed for us. He said to call the Honeywell people to get help with it. I think your videos and the manual answered all of my questions except how to turn off the cooling mode. We have a separate thermostat for AC, but he accidentally set these thermostats in a way that asks me to program the heat and AC modes - which is just annoying because it is time consuming. Thanks for making these helpful videos!
EXCELLENT! Much easier and simpler compared to the user manual! And thank you for not having any music in the video; which can be distracting!
I agree! This was a straight-forward and easy to follow set of steps. Thank you, Mr. Franco.
Thank you this video greatly helps I been going crazy looking all over youtube for how to use this thermostat This winter has been very cold not like other winters before that where much warmer Now I'll know what to do as I have not had to reset it before
Best video on this overly complicated thermostat.
I was locked out for a long time , thanks so much for your information it was so helpful. Quick note 1234 is the universal unlock .
The previous owner left this Thermostat without programming. Here there is a temperature excursion for 14C - About 12C in the night and up to 26C peak during the day. - So having to ability to switch over night from cooling to heating was critical, but I had to do it manually. This, until you shared the ISU settings. I modified 300 only, to allow for automatic switching, which is a no brainer for people that have cooling and heating. - But I forgot to set the "Mode" to Auto .. so at first it didn't seem to work. - But then .. this morning.. woke up with a nice 23C. Thank you for your help with this. Really appreciated. :)😃
This video just saved me from waking up in the middle of the night, Sweating like crazy because prior schedule was set up and I wasn’t aware. Simple programming is off currently lol.
You saved me 300 dollars god bless you
Glad i could help!
Thank you so much for detailed information. Your video is so helpful. I watched so many videos but nothing worked. Thank you
Thank you man! This takes rocket science 😅
Thanks buddy it was hell before your video
Great video hate this thermostat!
thank you. Our new home has the T4 but right out of the gate, no program option. Checked your vid’s and turned on the program feature under ISU 120. Not sure why it was installed that way unless it’s the default. Anywho, keep it up. Huge help!
OMGosh this video is a lifesaver.
Excellent presentation! Finally, I was able to turn off the programming! Thank you so much!
Glad it helped!
Thank you for this video. Adaptive Intelligent Recovery was driving me crazy! Now it's disabled.
Thank you, have been trying to figure out why this thermostat doesn't follow my schedule, turns out it's got some adaptive recovery setting that tryst to get it to temp by the time the schedule says. Not good for a time of use plan, but this video gave me exactly what I needed to turn it off, thank you!!!!
You're the man! Before today, I didn't even know the thermostat in my rental was programmable. Couldn't find anything online about those advanced configuration opcodes either! Glad I watched before messing with configuration settings! haha
Thank you for useful and clear explanation .
Hi John. Thanks for your video. Very helpful. Is there anyway of keeping the back light on permanently? When the light go off, I cannot read the themostat from a distance.
There is no way of keeping it on. Must press a button to temporarily illuminate. Thanks for watching!
Great video but what do you suggest if the unit stops blowing heat and air and just makes a hummm sound
I needed some Freon when mines did this.
Thank you for the isu list!
Thanks for watching!
Your 👏 Awesome!!!
Thank you!! This is amazing Video and pretty much cleared everything. My question is can we completely shutdown (power off) and can power on again? Its unnecessarily running whole day and night
So if it’s on the manual mode will it run to the set temp for the heat and then shut off when it gets there? Then start up again when it drops a few temperatures in the house? Or is it like a permanent hold?
John love this video
Honeywell should take this piece of technical crap off the market for users that aren't engineers or computer programmers.
Very helpful!
thank you so much, you have explained it very clear
Great video... Do you know if there's a setting for the Ability to automatically restart the thermostat after a power failure.? I'm in process of moving in. When no one's home, the furnace will not go on, will it? What if another outage when no one is home to restart thermostat?
it runs off batteries its independent of the system it controls. So losing power the thermostat doesn't even know that has happened it just continues on normally. But your heat or cooling system my reset and is what you may be referring to i think
My father has it set temporary hold which it goes to 62 and he told me the number on the bottom doesn’t matter that I just set it to 70 @ 8am & 70 @ 10pm.
Great info. Thank you !
Thank you, This helps A lot.
thank you excellent....kudos to you.🤗
Hey thanks. I don't see a link to the second video or the link to the manual. Like to have access to all.
The temporary and permanent hold messages are in small font and thermostats are often in poorly lit hallways- far from ideal to see the hold status The control head needs a red led to indicate that a temporary hold is in effect
Thanks this guide was helpful
My thermostat is reading a top number of 68 and a bottom of 74. I am trying to use the AC and it’s not turning on. It’s on cool setting and it’s says cool is on, but nothing is kicking on. Please help!
Same here following
Have it on 68 and reading at 77-78.
John WTH please help!!
Same here I’m dealing with this right now
Same
Hi, thank you so much for the video. Where can I get a copy of the list?
How do I get it to turn below 70 degrees
THANK YOU!!
You're welcome!
I have been struggling so much with it. We have 110 degree heat here and need that a/c to stay on! It kept reverting back up too high. Now I got it set on "permanent hold"! Yay! God bless you;
This is the worst, no the worst was Honeywell's wifi but this is a close second. No manual, no way to set it up. Terrible thermostat!!
What happens if the heat option is on, the room temp is 70, the set temp is 60? Does the unit stay off until the point the room reaches 59, then kicks on?
Keep up the good work budd 😊😊
Question, if I set the thermostat to 75, is there a way to get it to come on at 74 and shut off at 76? Right now it stays at 75 and runs too much!
The triangle is on above the fan auto is that suppose to be on. Thanks
Is there a way to change any of those ISU settings without factory resetting the whole device?
You said you'd post a link to the CODE SHEETS. Where's the link?
Great ℹ️
My hold setting is completely gone… I press menu and it just says prog for the 1st setting
100 degrees today, 111 predicted for Sunday and my thermostat finally decides to break down, you can’t be serious.
wow i feel for you. Hope this info get you back up and running
Good job budd 😊
Thanks. Special, additional, thanks for NOt running a background music/ sound track. WHo thinks that's a good iDea? Why?
Have the Honeywell Home pro series. Why isn't Option for permanent or temporary hold not displaying
informative thank you but I do have a small triangle with ! in the center? can you address that ?
Have just bought a Honeywell RTH6360 and the room says it's 78 but it's really 73 so the AC keeps going and doesn't get read the temp. How do I calibrate the temp?
thermostat may be in a bad spot or in direct sunlight. make sure there nothing block the thermostat
My fan is on auto but it still won’t turn off, it’s going 24/7. I want it to temporarily turn off and on like a regular ac. We had to replace our ac unit 2 months ago and the fan has been going 24/7 ever since making my bill and humidity in the house go up.
If its set to programable does that mean once it reaches the desired temp it will turn off then back on based on the differential temperature ISU code 303? Mine currently runs at ISU 365 stage 3 and it runs at 10minutes on and 10 minutes off but you didnt go over the codes functions
great video, thank you so much! I hate this thermostat! It's at my leased office.
What is the triangle with the exclamation point warning or alerting me to!
Mimes say cool on when I know I had cool auto options
What am I missing
I hate this thermostat! You need an engineering degree to use it. Bring back the simple dial thermostat! I
My issue is that the thermostat has a mind of its own. I have the heat on right now at 75 degrees but there are days and times where it randomly goes down to 68, 65, 60. The other night it was 58 degrees in the house, so cold. And then randomly it'll go back up a few degrees, etc.
I have central air. Furnace. I change the filters every few months. And I bought the house back in 2020 and it was a fully remodeled home. So everything is new.
I was told to maybe replace the thermostat.
Watch part 2 it probably needs to be programmed to follow schedule for the whole week as you desire. So it doesnt jump around like you are saying.
I'm not using the programming right now and I had that problem. I found it was on temporary hold instead of permanent hold.
Hey John, how would you correct this problem the thermostat shows “!” On the screen
It won’t accept the time of the date even though it says it saved and I can’t get into the programming
My thermostat is stuck on 32 for inside temperature. It was working fine until I replaced the batteries. It’s about 80 degrees inside and can’t get the ac to turn on
I appreciate the video, but could you be a little less specific and more to the point
Shouldn’t you start out by showing us how to unlock. That’s where I am stuck. I’ve just put two new batteries in, I do not know how it got locked. But that’s where I am stuck.
Try 1234. That seems to be the factory unlock.
Hi friend, Which option for Fan is better? Fan on or Fan auto? which option should I choose?
Fan Auto
Your information is perfect thank you very much
Glad it was helpful!
I program my thermostat and it doesn't conform. it is set to go to 20 at 10 pm and to 24 at 630am. However some between those settings it goes to 24 beforw 630 am. At one tine when I noticed it the "restore" indicator appeared beneath the heat on indicator. How can I correct this ? Thanks in advance for your response
Hey man, great video. The default password of 1234 is the first thing the other people in my house guessed and they keep unlocking and changing the temperature.
It won’t allow me to change the password.
If I physically remove the face of the unit off the wall, will everything still run with the last settings it was on? I hate this thermostat.
Hi thank you for taking the time to find these codes. I am trying to review your video to see if a code is specific to where the cool air goes. My AC used to flow strong in the master bed / closet. I went into the ISU and may have adjusted 120/2 or 300/3. One of those changes Celsius and Fahrenheit.
I thought I changed it all back but my bedroom at 90’ used to feel manageable and the Ac turned on quickly. Now at 84’ it feels hotter like 95’. Of course the apartment setup is flawed so the AC is in the master and the thermostat is across the other side of the 2 BD apt
it barely cools the bed but does cool the living room. So if you know of any settings that may adjust Cool
settings or where/how the unit turns on or flows I would appreciate it greatly.
PS- is there a URL you can share for where u finally found the codes with the other model. Thanks!!!!!
Sorry for so Many questions but this is a legit concern as it’s 120 here. The very first code you mentioned 120. You said they were option zero through four, but I have no idea what any of those numbers refer to. You may have a basic understanding of how these devices work and you may know how to interpret those numbers, but I have no idea which number I would use if I change the setting I have no idea how to determine how to set it back. I’d experiment but it seems that is a complicated way of trying to figure this system out.
Okay can finally zoom into your video to see the paper. Could not initially zoom or read your reference papers.
check out my thermostat playlist. i have a video going over all the ISU functions #s and closer up
@@JohnFrancoNHwhere is it? I’d like to print it out myself, do you still have the website?
You can help me , right now too hot ,I’m try reset the same this video but my home too hot, I don’t know why my house big number alway 87 ,I control little number 70 or 65 but big number not down,help me how do that .
if your a/c is working correctly that big # takes some time to come down. A/C could need to run for a whole day to manage the heat load in your home and to actually cool. Always leave it on so it manages the temp 24/7. Huge temp differentials put a huge strain on the system and will not cool as fast as leaving it set all day all week to hold 75F for example.
I want my old mercury thermostat back.
My Honeywell Home switch is completely off. I mistakenly press the timer and since the device was off. it isn't easy to turn it on. Please advise. Thank you
Me too. Had a power glitch and can't get it to work l
How do i change it back to where u got it its blowing cold air
My reverse valve was stuck in heating mode . Should I change it to 0 ?
What does it mean when the word battery is above the temperature number?
Would you please make a video to set up how to turn on Air conditioners only using HONEYWELL Home T4 Pro Thermostat? Thank you.
How do you relax it
I hate this thing always seems to overdue it or under do it. Then, I dropped it and screen isn't reading out. Still worked, but I must have hit a wrong button, turning it down a bit. Now due to this being stupid over complicated for a thermostat, I'm freezing ... great job Honeywell. Let's hope I don't blow out the central air guessing.
Maybe the thermostat should be located on a better inside wall. yes dropping it doesnt help either. I would recommend fully programming each day and time period as desired and making sure the device settings are all correct for you heating cooling type in your home. And also watch part 2 this will guide you thru programming the T4 to follow a day to day schedcule.
All I need to know is how to turn on and off ...plz do a video of how to turn off and off first plz
If the batteries fall out, do you need to reconfigure the ISU or the adv. Setup options??
Not if you put them in right away. If they stay out for months it could have total reset itself
It appears I have walked my thermostat because in the bottom middle of the thermostat it says unlock. How do I unlock the thermostat?
My thermostat lights up when you press any button but is completely unresponsive no matter what button i press even though it lights up. How do i fix that issue?
im trying to figure this out as well, any fix yet?
@@Sukaibureika nope still no answer lol
Hopefully you can give an answer as to why it doesn’t go into program but only into time and date
Why does my cool on continually flashing?
Mine is used and is stuck flashing the year on the screen. None of the buttons or factory reset is working from that screen except for me being able to change the year forward but not select or back.
Thermostat just started buzzing. What's the cause of this?
If the battery has died for about a day , must I reset the entire thing?
