The introduction ''...the simple to use Greenstar Comfort Controls Range'' got me. Simple to use my a**e. It's an absolute nightmare, and I regard myself as a bit of a techy who doesn't struggle with such things normally. But, much praise is due to the presenter in this video for explaining the basic functions in such a precise and well-timed manner. Thank you.
BRILLIANT! I have been trying for months to set my boiler after electric had to be off a few hours. Your instructions are absolutely clear and precise! Thank you so much. My boiler is now up and running in perfect order and timed heating coming on when I’m out and going home to a LOVELY WARM HOUSE !!! Thanks again !
I tried to figure out how to change the clock time and date but the instruction book didnt even give you the basic knowledge. It told you to press the menu button but none of the instructions told you which one it was! Thank goodness for TH-cam. The video clip was brilliant. Thank You so much
Yep, I've been told by the fitter how to switch the rads on when I need them on and I tried it and it doesn't turn the rads on and so I tried a slightly different way using my common sense and it still didn't work. I've watched 2 videos of staff showing how to use this, and both didn't show you how to simply just switch the rads on and off FFS!?
Hurray! having tried and failed to understand the instructions in the manual; having watched this video I now understand what to do. Bravo for plain, clear instructions delivered in clear English!
I have had my Greenstar 30 Boiler since January 2017 and it is a permanent nightmare. I have spent more time in the COLD than being warm the history is endless including 2018. As we enter 2019 and snow is all around again four days in the cold but when I did get through to the helpline they were excellent and helped me reset the ‘ Paring’ Thank You. Why can we not have a simple ON/OFF system? My last Worcester Boiler lasted me 35 years, only serviced once and never called engineer.
My problem is not with the video but the timer in general, I would like to set the whole week for 1 on time and 1 off time, this is not possible it forces you to set way to many. I work from home so don't need that many options. With the old mechanical system you could do what I require.
@@jsutton892but it's not the end of the world if you have too clocks, no? It works for most Monday to Friday workers who don't need a early heating start
Brilliant! Thanks for this! I can't believe such basic information wasn't included in either of the boiler manuals (seriously). This video was a lifesaver.
@@TheMaisiemay13 the only thing I wish I could figure out is getting a constant temperature on the water it's up and down like a bloody yoyo, I never had a problem like that on my Valiant boiler since I have this Bosch boiler it's terrible with that the heating of the water
Absolutely fantastic instructions. We tried to put our heating on today as not used since Mar h/April , to no avail . I watched your video and noticed that date and time had been lost, had got back to 2018. Step by step I followed your instructions and easy . Thankyou from a 66 year old lady lol . I am my techy than my partner bless him 😂😂
Thanks for this video. I just spent half an hour trying to figure out how to get all days - Mon-Sun. Your video shows that it isn't possible. Apparently, this boiler doesn't cater for retired people. I expected it to be like the typical electronic mains timer plug, where you can select individual days, week days, weekend days, or every day.
Hi Mike, separate days can be set, but the video does not show how to do this. You can call our technical team on 0330 123 9339 and someone from the team can talk you through it. Many thanks, Worcester
Worcester, Bosch Group - Thanks for the reply, but I don't think it's possible. After a lot of reading the manual, watching TH-cam, and general messing about, I finally figured it out how to get it all set up. I set times for all weekdays, then separately set times for the weekend days. The boiler doesn't cater for retirees, who are there every day - but that said, once the method is understood, it isn't much extra effort to set the weekend days. However, hitting on the method isn't straightforward. The button operation (which button to press at which time) is certainly not intuitive, and the customer brochure doesn't give much help either. Before you design your next boiler, you should fire the design team responsible for this and get a new bunch in! I might just mention that I was setting it up for the lady next door. I thought I'd be up to it, having spent a lifetime in technical support of large computer systems - but when a company is selling to the general public, they have to make the controls suitable for the use of people who have no idea of technology. The lady next door is terrified of this boiler - to the point that she has been living in a freezing house over the new year period, with the boiler switched off.
Thank you so much !!! Installers left everything on constant after telling me they had set the timers and programmes,,, you were with me in the boiler house putting it all right ! Great stuff , thank you 🙏🏻
Lora Timmins I’m in the same boat.. just figured out that you must have the same temperature set on both boiler and the receiver on the wall.. just did that and the boiler fired up
@@Gojulee glad you got it working! think mine wasn't working as the time and date were completely wrong. Adjusted the clock and it roared up 🔥nice to have some warmth!
Lora Timmins glad you also got it working .. now it’s too bloody hot haha. Just having to sit and wait now to see if the auto will turn off at 10:30 tonight 👍🏻
This damn thing breaks every single principle of good design. If you have to publish a 10 minute video on how to use a fucking *thermostat* that almost 300k people have watched, then you've failed at making your product useful. Thankfully this video is fantastic, great job to the production team.
Thanks, VERY useful information, A lot easier than trying to negotiate through the manual. I as a techy did not find the control easy to use, A good presentation,
We run a computer company, we are tech savvy. This is the most counter intuitive device I have ever come across. EVER My plumber had to go away with the manual and he sent me to this video as he couldn't work it out and he deals with these things on a regular basis. I will set it up once and hopefully the batteries will last a long time because this device is appalling.
Hi I was just going to buy one of these from eBay but your comment has put me off...what clock would you recommend for the greenstar 30i plz....many thanks
I'm retired now, but spent my life incomputer hardware tech support on mainframes, so you'd think I'd be as well placed as anybody to set this up with minimal instruction - but I entirely agree with your feelings. There's absolutely no way to set this boiler up without instructions, and the ones that come in the "manuals" (I use the term advisedly) fall a long way short of the mark.
Entirely agree, the printed manual is appalling. I have spent a lot of time trying to work out how to reset the clock to GMT after the clocks were changed last week. The video has enlightened me, but how do Worcester expect elderly customers who have lived with analogue control all their lives to even begin to understand ? Also, my old Salus room stat had a blue pilot light to indicate when calling for heat and this feature was very useful, the LCD is a backward step Worcester, and judging by the comments above the wireless control is not proving to be very popular.
We just changed our Worcester s couple of months ago. Only just tried to make out the user instructions, forget it! Thank goodness for this video, I managed to do it straight away while watching the video on my iPad. Thank you so much.
Thank you for this clear video. Far more helpful than your helpline that wanted to charge me £5 per month to answer a simple question and by watching this video I realised all i needed to do was reset the clock, because we had had a powercut and the clock was wrong causing the heating to come on in the middle of the night. The online assistant couldn't figure that out and tell me to check the clock and wanted to charge me £5 per month for the privilege. Thank you.
Thank you for, I hope, clear instructions, the little manual is confusing... I shall now attempt to update the settings..... phone alongside I followed the instructions and it was easy..... thank you
My Comfort 11 Controller does not have Heating "On" and "Off" times. After much faffing, I have realised that my Controller is designed to have the heating on all day, but is set in four "time zones". You set the time on for the first time setting and the temperature for that period. When you want it to turn off, this effectively is the start of "Time setting 2". By selecting the temperature for time setting 2, you can effectively turn it off at that point by choosing a low temperature through to when you want "Time setting 3" to start (e.g. 16:30). By setting a higher temperature again for that period, the heating comes back on again until "Time setting 4" (the time when you want it to go off) by turning the temperature right down, or off. To clarify: 07.30 on at 22 degrees until 09.00, reset temperature to 15 degrees going through to 16.30, reset temperature to 22 degrees to 21.30; reset temperature to 10 degrees to turn off. Nightmare!
Thanks for this! I've the 2rf and been tearing my hair out how to set the heating to go off. What a bloody stupid programme, it doesn't make sense! The 1 rf had 'timer off' settings so wht get rid of them on the 2rg??? Soooo stupid!
@@nikkicooper9928 Yes, it takes some getting used to, but having got the gist of it, I actually quite like the format. It is nice to know that the heating will come on when it drops to a certain temperature (decided by you), rather than it not come on at all because it is set to "off". It is especially good when you are at home all day and like to keep the house at a comfortable temperature which takes into account the weather outside. Having torn my hair out for days on end because I was used to the "on-off" format, I have to say that I actually prefer it. Just takes some getting used to.
Thank you so much for this comment, I always have the same format as you and was really struggling to understand how to set the times. Out of curiosity can I ask what you have your target temp set at please? How does this feature work?
@@chelseasanderson3376 Hello Chelsea, thanks for your question. In answer, your target temperature is one that you decide is comfortable for you. Personally, I have set my heating to come on at temperature 20 degrees first thing in the morning, (say 7.30am - 9.30am) (temperature 1) so that the house and bathroom is nice and warm to get up to. Thereafter, if no-one is at home for the day, then turn temperature 2 down to say 15 degrees from 9.30am until half an hour before you get home (say 5.30pm). This is effectively turning the heating to "off"; the heating will only come on if the temperature falls below 15 degrees. Then set temperature 3 (home time) to, say, 20 degrees from 5.30 pm until half an hour or so before bedtime (say 9.30 or 10.00pm) (temperature 3). Thereafter, turn temperature down to say 10 degrees during the night (effectively turning the thermostat off). (10.00pm-07.30am). The temperatures you choose are entirely down to you and what you find comfortable. Of course, if you live in a particularly cold climate, then adjust these temperatures accordingly. Hope this makes sense and good luck.
Worchester Bosch , the company who sells thousands and thousands boilers a year and yet cannot do CLEAR and PROFESSIONAL instruction video. There are thousands of customers who are single mums, elderly or just those who`s English is not their first language. They are certainly none of the wiser after this video. For a company that big.....it is a shame.
We ended up paying extra to have an old time clock fitted to our worcester boiler, the comfort controls are so complex to use , imagine old people trying to understand and use this , our gas engineer said it is a complete nightmare trying to explain this to people and we gave up in the end and had to pay an extra £200 to change! I completely agree with many of the other comments that this was designed by idiots, Worcester I hope you read this and suggest you go back to the drawing board and redesign with customer use in mind.
It's not just bad for older people - we are a couple in our late twenties and we are SO confused by this terribly designed thermostat! Going to buy a Nest to use instead
Hi my mum is having a problem with greeenstar 4000 boiler rf 11 comfort control. Thinking of buying a timer (MT20) - can I ask did you buy a timer and how did you get on with it? thanks Mary
Does anyone know what "on" setting does for heating? Does it ignore the time programme? I thiught i could juat set it to ON and then control via the thermostat. Very useful video by the way better than the manual...
I think in my last house I had a Honeywell controller. Do you have a product that is simpler to understand, and doesn't work with either radio signals, nor the fingery clicky things
if it's the timer functions you want to set you can get to that by holding down the bottom right button for a few seconds and then a screen with different functions will pop up then just use the knob to move left and right on the screen and press the knob to access, it shows here at 1:44
Thank you ... very helpful, managed to follow instructions ..... 69yr Female. A result i would say. :-)) ... your further information / overview is also helpful....... thanks again.
Hi. Your video is so easy to understand but how do you set the Preheat to come on all day from 8am until 9pm at night, without pressing the on mode. I entered 8am till 9pm in the DHW1 programme is this correct or should I be entering 9pm in the DHW2 programme? Also selected Once, should it be on Auto? Just had the boiler serviced and now the Preheat isn't coming on at 8am for some reason. Any advise other than getting the engineer back in. Thank you in advance.
I have comfort + IIRF. My setting 1 is at 7.40 a.m. 20 degrees. My setting two is at 16 degrees, 8 a.m. Setting 3, 7.45 p.m. 21 degrees. At 9 a.m. the boiler is still on with low heat at my radiators. In other words is there no off time when set at auto?
Question - I have a 2 rf, why isn't there an option to set an "off" time?? From this video it seems that "auto" mode is similar to "on", with no Off time function my heating is permanently on, and all that happens is the temp setting is altered to lower. So my heating remains on at all times but will constantly cut in and out according to the temp setting. I'm concerned that leaving my heating in auto mode is going to increase my heating bill, and it would be cheaper to just turn it on and off, is this correct? Fyi I live in a rental property so have inherited this heating system.
Great video, thank you. I have this boiler the compact. I would like to know how to set the timer for just one time. One start time and one switch off time (not 2 times in a day) Look forward to your reply
My mam is 87 year old has just got a gree star comfort control for her boiler she just wants to turn in on an of she’s struggling can I get any instructions for her
I don't understand why with the Comfort II RF, you have no ON/OFF times for the heating...you effectively have to have it on from start to finish (albeit at different temperatures through the day). The Comfort I RF has clear ON/OFF periods...why can't I do this with my II RF?!?!? All I want to do is set Timer 1 from 05:00 to 06:30, and then off until Timer 2 from 17:00 to 20:00! How can this be done?
@@fannumfox I think the idea is by turning the temp down to say 5 in the 2nd timed sequence the boiler will not be running so effectively it's off, but in a safe setting so as to prevent system freezing in extreme cold conditions
@@stewartclifton3068 thanks a bunch for your reply. I just realized 1 thing, when in setting 2 i set temperature at off, heating actually switched off st that time duration. What do u think its safe ? Or setting it at 5?
I have set the times for it to come on and go off. Set the correct date and time, but it seems to turn off randomly and not come on when it’s set. Any advice? When I went to set hearing times, did not show temperature just the times
I have comfort II. How to set off time for boiler? When selecting time? Its a pain not knowing when heating will go off? As i simply want to set heating 2 times each day. 3 hours morning and 3 hours evening. How can i do it? To set from 5.30-8.30 & 16.30-19.30???
I found this brilliant explanation in you tube comments* . I could not understand the Comfort II but I've got it now. Set the 1st time/temperature at your required temperature, then 2nd time (8.30) at say 10 deg (the boiler will not fire up if your house does not fall below 10 deg! It will stay off till the 3rd time setting. Set the 3rd time (16.30) at your required temperature. Set the 4th time at say 10 deg and again the boiler will not fire up. It will sleep peacefully until 5.30 in the morning. Press the button to ignore the 5th and 6th settings as shown in the video. Neither my heating engineer nor Worcester Bosch technical department could explain this to me - and the user manual makes no reference to this whatsoever. I could not figure out why the boiler was not "turning off" when I thought it should. Good luck, and you will see - it wont be using any gas during the 10 deg period (of course if the room where your thermostat is gets colder than that (!) you'd have to set a lower temperature - say 5 deg - which is what they recommend if you go on holiday - it just keeps it in frost protection mode. Not necessary to go any lower than that. the Epster
2 years ago * Basically this is a 24 hour temperature profile system allowing up to 6 programmable time zones set at given temperatures for that period. There is no on or off setting as such as this will depend on the temperature setting. If you want it off during the day, set the desired temperature to zero. Most working people will want a lower setting overnight, say 16C, then up to 20C when they are getting ready for work, then low or off during the day, say 10C, then back up to 20C for when they return from work until going to bed; hence four temperature time zones. The controller, however, doesn't cater for retired or non working people at home 7 days per week, for this you need to program mon-fri and sat-sun the same. The override feature allows you to jump to the next zone if you arrive early from work for example. The Wave allows you to do this remotely via an app. I guess this system is a set and forget controller with holiday override. Alternatively the lower spec unit just gives three on/off daily settings. Only concern is when the battery dies or if this unit malfunctions. This being the issue with complicated controllers is all types. The Wave needs constant wifi for example and access to an iPhone or iPad.
Hi brilliant video, very useful, but please can you tell me why I need to set the different times for the hot water, when I would rather be able to use it at any time? Also, I find the water too hot, how do I change the temperature of this please?thanksI have a new Greenstar Comfort II RF prog
Hi Berverley, I wondered the same about the hot water, I thought it would be available 24 hours a day. To change temp of hot water just turn the right hand knob down a number. Ours is set on "e" for economy, but you can go up to 6 or down to 1 or min.
Hi Beverley, thanks for your feedback. Hot water will always be available on demand for combination boilers, the timings would only be applicable to conventional boilers which use a cylinder. Please refer to your boiler installation manual for information on adjusting the temperature of the hot water.
Why do you need to select on/off times for the water. I thought a combi boiler supplies hot water on demand i.e when you turn on the hot water tap the boiler kicks-in and heats up the water.
These boilers have a pre-heat function so (in theory) you will get hot water at your taps faster then just heating on demand. In reality it is mostly a gimmick that just wastes gas and you're probably better off just setting it to "off" where it will act like a conventional "on-demand" combi boiler.
How do I use the controls that are on the boiler itself (not the unit that the video's about)? In particular, I want to know how to turn off the eco setting. (I'm pouring away a lot of water waiting for hot water to come out of the tap.) There's a set of three buttons on the boiler. One of them is the eco button, but it seems to be linked to the other two. Can I just press the eco button to turn of the eco setting, or will that have knock-on effects? I have a Worcester Comfort II RF.
Thank you for your comment. The two controls, boiler and Comfort II RF, work in conjunction with each other. For easier control, press the ECO button on the boiler until it shows either 'Preheat' or 'ECO with a clock symbol', then use the hot water settings on the Comfort II RF to control the preheat, either Off (no preheat), Once/Timed (Preheat follows the programme) or On (Preheat on all the time). We will be happy to send an instruction manual to you for your Comfort II RF control, please get in touch with our contact centre on 0330 123 9339 or alternatively send an email to service.mailbox@uk.bosch.com and we will just need to take a few details to send the manual out to you. Thanks, AW
Thanks. So the Comfort II RF is the programming device, not the boiler. And it seems I can't simply turn the Eco setting on and off at the boiler; I have to program it so that the programmer turns it on and off. Similarly it looks as though I can't adjust the temperature of the heating directly; I have to program the programmer to do that. If I want hot water now or a change in temperature now, I first have to have a plan for the whole day - or the whole week. Have I got that right?
We believe that it would be best to discuss this directly with you. Please could you contact the technical department directly on our free number, 0330 123 3366, and our advisors will talk through all the settings on the Comfort programmer as well as the boiler. Many thanks, Worcester
Why do you need to set the hot water times as the boiler only heats the water you draw down with a tap? What does setting hot water times achieve? As there is no tank with a Combi boiler.??
Cam anybody explain why the heating seems to be in some sort of limp mode ?, my boiler picks and chooses when it want to fire up quickly or slowly? Boiler has been fitted correctly and system was flushed . I just don't understand
So, we have a remote counterpart, but can't find it. It seems that the main comfort controls won't override that remote, though. So the boiler is completely off and can't get it back on? Wireless room stat is what you called it.
Hi Nathan, I would recommend giving our tech team a call on 0330 123 3366 as they may know a work around. It sounds as though you may have to look into a replacement wireless stat, hopefully the tech team can help you get this sorted though 😊🤞 - Aiden
Hi Sarah, The hot water side of the comfort controls range (when fitted to a combination boiler) is to time the pre-heat function of the boiler. This effectively keeps a small volume of water within the heat exchanger hot. This will ensure that hot water is delivered almost instantly to the opened outlet. If you are not using preheat, the boiler will be in ECO mode and the hot water will be heated from cold. A slight delay should be expected before the hot water is at full temperature when the boiler is operating in ECO mode. By selecting ECO mode, less gas will be used as energy is used only on demand. Regardless of the way the boiler is used (Preheat or ECO) a combi boiler will work when the tap is opened. Hope this helps, EH
This video is great but I have both of mine I. The on position but no hot water at all! I have tried all different ways with timings on the auto then pressing advance but nothing. Could it be faulty??
I have a Worcester Greenstar Comfort II RF and this does not seem to have a 'Once' selection for the Central Heating, only On, Auto or Off. The water does have a Once selection. Is this correct or am I, maybe, doing something wrong? The Once function is very useful for those of us who are at home for most of the day.
I have managed to set the times to come on but once I have set each time it doesn’t ask me what temperate to set it to and I can’t seem to find it anywhere else in the menu? Can anybody help please!!
So looking at the docs it just slots in and small connector plugs in to the boiler Is that it, what about the old on wall rotary timer and the thermostat Does it over ride them can they be left in place
After a very short power cut I tried to do a time/date reset. I somehow changed the language to german, and now can't get it back to English. HELP please.
I suppose you can get over tech on a narrow subject. I spent 50 years in tv, video servicing and after spending hours programming video recorders I found the Greenstar comfort quite easy to programme up. flow chart quite easy to go through.Like everything, if you are familiar with the subject it comes easy, if not its a pain. Don't give up
I would like to know how to change the batteries in my comfort II RF controller and would I need to reset all my program settings after doing so? Thank you.
Hi Ray, please find below a link to download the manual. www.worcester-bosch.co.uk/professional/support/documents/greenstar-comfort-ii-rf-installation-instructions . Replacing the batteries can be found on page 18. The controls will retain your settings for up to 6 hours after losing power. Thanks, Worcester
A thermostat will go on room temp, that’s the idea, if the room temp matches or is above what you have set the heating will stay off, if the temp drops below the heating will turn on. The RF1 shows the current room temp on it, to adjust just twist it, it will show the new required temp and flash whilst contacting the boiler, if your going hotter then you will see a little flame icon appear, this means your boiler has received the request and is operating Don’t forget all the timer does is turn the boiler on and off according to the times you have set, the thermostat still controls what temperature you require, sounds like you need to make sure you are using the timer function and not the always on setting
@@djhatstand7312 Hi just responding back to your message as my boiler says on but there's no heat coming out of it. Do I need to turn my thermostat high for it to stay on?.
I work from home, all I need is an "ON" for morning and "OFF" at night for everyday of the week. The RFII is a pain in the butt to program. The heating is set to go off at 23:00 but stays on all night on Saturday/Sunday. Why has the RFII not got a ONCE option so that it will come ON in the morning and go Off last setting at night.
Found this video easy to follow. Much better than the booklet!! Only thing is how can you override the timings if you want the boiler to stay on longer at night.?
Hi Diane, the reason the Comfort II shows the frost symbol when the heating is set to off is that it is effectively running in frost protection mode only. This does not impact the hot water timings. Please let us know if you have any further queries
I HATE this system. I'm not in control. Whatever happened to On and Off? I have to set the temp very low so it doesn't come on randomly while I'm out. Also I don't go to bed til late and I've yet to find out how to set the control to go off AFTER midnight. I've tried 00.30 but it won't stick. Anyone know?
On the right hand side of the controller comfort 11RF (controlling hot water)the off sign is shown and was set by the engineer last Friday when boiler and controller were installed.This was in response to our request to have hot water available all the time. However the video states that it should show on for hot water to be available 24 hours of the day. I am confused Can you clarify?
Hi Terence, as this boiler is a combi boiler whenever a tap is opened the boiler will fire up to satisfy the demand. The on/off/timed functions on the programmer are in relation to the pre-heat function. Let us know if you have any more questions, or you can call our team on 0330 123 9339. Many thanks, Worcester

Why can we not have a simple ON/OFF system? My last Worcester Boiler lasted me 35 years, only serviced once and never called engineer.
Ah the good old days eh. Don't make them like they used to
Not sure how people can dislike this vid, it's fool proof and what I love even more is you can skip to the part you need. Nicely delivered too!! 😍
My problem is not with the video but the timer in general, I would like to set the whole week for 1 on time and 1 off time, this is not possible it forces you to set way to many. I work from home so don't need that many options. With the old mechanical system you could do what I require.

Absolutely fantastic instructions. We tried to put our heating on today as not used since Mar h/April , to no avail . I watched your video and noticed that date and time had been lost, had got back to 2018. Step by step I followed your instructions and easy . Thankyou from a 66 year old lady lol
. I am my techy than my partner bless him 😂😂
Thanks for this video. I just spent half an hour trying to figure out how to get all days - Mon-Sun. Your video shows that it isn't possible. Apparently, this boiler doesn't cater for retired people. I expected it to be like the typical electronic mains timer plug, where you can select individual days, week days, weekend days, or every day.
Mike Collins I haven't got a clue ,I just got left with a load of bummff and they fucked off
Kev, if I didn't get anything else from that, I surely got a good laugh.
I think just leaving bumph and fucking off is their modus operandi.
Whaaaaa ,,damn right shit your place up the scoot off
Hi Mike, separate days can be set, but the video does not show how to do this. You can call our technical team on 0330 123 9339 and someone from the team can talk you through it. Many thanks, Worcester
Worcester, Bosch Group - Thanks for the reply, but I don't think it's possible. After a lot of reading the manual, watching TH-cam, and general messing about, I finally figured it out how to get it all set up. I set times for all weekdays, then separately set times for the weekend days. The boiler doesn't cater for retirees, who are there every day - but that said, once the method is understood, it isn't much extra effort to set the weekend days. However, hitting on the method isn't straightforward. The button operation (which button to press at which time) is certainly not intuitive, and the customer brochure doesn't give much help either. Before you design your next boiler, you should fire the design team responsible for this and get a new bunch in!
I might just mention that I was setting it up for the lady next door. I thought I'd be up to it, having spent a lifetime in technical support of large computer systems - but when a company is selling to the general public, they have to make the controls suitable for the use of people who have no idea of technology. The lady next door is terrified of this boiler - to the point that she has been living in a freezing house over the new year period, with the boiler switched off.
Thank you so much !!! Installers left everything on constant after telling me they had set the timers and programmes,,, you were with me in the boiler house putting it all right ! Great stuff , thank you 🙏🏻
I hate the Boiler
Thanks for this! Previous owner of my house didn't think it was necessary to leave the instructions for anything and it's getting chilly!
Lora Timmins I’m in the same boat.. just figured out that you must have the same temperature set on both boiler and the receiver on the wall.. just did that and the boiler fired up
@@Gojulee glad you got it working! think mine wasn't working as the time and date were completely wrong. Adjusted the clock and it roared up 🔥nice to have some warmth!
Lora Timmins glad you also got it working .. now it’s too bloody hot haha. Just having to sit and wait now to see if the auto will turn off at 10:30 tonight 👍🏻
Thank you my housing install your boilers but dont hand out books on how to set them so this was brilliant for me thanks again
Same for me too
This damn thing breaks every single principle of good design. If you have to publish a 10 minute video on how to use a fucking *thermostat* that almost 300k people have watched, then you've failed at making your product useful. Thankfully this video is fantastic, great job to the production team.
Thanks, VERY useful information, A lot easier than trying to negotiate through the manual. I as a techy did not find the control easy to use, A good presentation,
Not sure sure how anyone can give this a thumbs down. It turns you into an expert and surpasses The mumbo jumbo in the useless manual. Thanks!
I'm thinking the thumbs down might be because the whole set up is simply not good enough!
This is such an excellent info video. Clear and although put up some years ago is still valid for my thermostat control. Thank you.
We run a computer company, we are tech savvy. This is the most counter intuitive device I have ever come across. EVER My plumber had to go away with the manual and he sent me to this video as he couldn't work it out and he deals with these things on a regular basis. I will set it up once and hopefully the batteries will last a long time because this device is appalling.
Hi I was just going to buy one of these from eBay but your comment has put me off...what clock would you recommend for the greenstar 30i plz....many thanks
cant get boiler to fire up
I'm retired now, but spent my life incomputer hardware tech support on mainframes, so you'd think I'd be as well placed as anybody to set this up with minimal instruction - but I entirely agree with your feelings. There's absolutely no way to set this boiler up without instructions, and the ones that come in the "manuals" (I use the term advisedly) fall a long way short of the mark.
Entirely agree, the printed manual is appalling. I have spent a lot of time trying to work out how to reset the clock to GMT after the clocks were changed last week. The video has enlightened me, but how do Worcester expect elderly customers who have lived with analogue control all their lives to even begin to understand ? Also, my old Salus room stat had a blue pilot light to indicate when calling for heat and this feature was very useful, the LCD is a backward step Worcester, and judging by the comments above the wireless control is not proving to be very popular.
We just changed our Worcester s couple of months ago. Only just tried to make out the user instructions, forget it! Thank goodness for this video, I managed to do it straight away while watching the video on my iPad. Thank you so much.
We're glad the video was helpful, thanks for your feedback!
Thank you for this clear video. Far more helpful than your helpline that wanted to charge me £5 per month to answer a simple question and by watching this video I realised all i needed to do was reset the clock, because we had had a powercut and the clock was wrong causing the heating to come on in the middle of the night. The online assistant couldn't figure that out and tell me to check the clock and wanted to charge me £5 per month for the privilege. Thank you.
This was very helpfull when setting my new boiler on/off times. Thanks
Thank you for, I hope, clear instructions, the little manual is confusing... I shall now attempt to update the settings..... phone alongside I followed the instructions and it was easy..... thank you
Clear and simple instructions. Just couldn't work it out from the written instructions. It's my age, I reckon!
My Comfort 11 Controller does not have Heating "On" and "Off" times. After much faffing, I have realised that my Controller is designed to have the heating on all day, but is set in four "time zones". You set the time on for the first time setting and the temperature for that period. When you want it to turn off, this effectively is the start of "Time setting 2". By selecting the temperature for time setting 2, you can effectively turn it off at that point by choosing a low temperature through to when you want "Time setting 3" to start (e.g. 16:30). By setting a higher temperature again for that period, the heating comes back on again until "Time setting 4" (the time when you want it to go off) by turning the temperature right down, or off. To clarify: 07.30 on at 22 degrees until 09.00, reset temperature to 15 degrees going through to 16.30, reset temperature to 22 degrees to 21.30; reset temperature to 10 degrees to turn off. Nightmare!
Thanks for this! I've the 2rf and been tearing my hair out how to set the heating to go off. What a bloody stupid programme, it doesn't make sense! The 1 rf had 'timer off' settings so wht get rid of them on the 2rg??? Soooo stupid!
@@nikkicooper9928 Yes, it takes some getting used to, but having got the gist of it, I actually quite like the format. It is nice to know that the heating will come on when it drops to a certain temperature (decided by you), rather than it not come on at all because it is set to "off". It is especially good when you are at home all day and like to keep the house at a comfortable temperature which takes into account the weather outside. Having torn my hair out for days on end because I was used to the "on-off" format, I have to say that I actually prefer it. Just takes some getting used to.
Thank you so much for this comment, I always have the same format as you and was really struggling to understand how to set the times.
Out of curiosity can I ask what you have your target temp set at please? How does this feature work?
@@chelseasanderson3376 Hello Chelsea, thanks for your question. In answer, your target temperature is one that you decide is comfortable for you. Personally, I have set my heating to come on at temperature 20 degrees first thing in the morning, (say 7.30am - 9.30am) (temperature 1) so that the house and bathroom is nice and warm to get up to. Thereafter, if no-one is at home for the day, then turn temperature 2 down to say 15 degrees from 9.30am until half an hour before you get home (say 5.30pm). This is effectively turning the heating to "off"; the heating will only come on if the temperature falls below 15 degrees. Then set temperature 3 (home time) to, say, 20 degrees from 5.30 pm until half an hour or so before bedtime (say 9.30 or 10.00pm) (temperature 3). Thereafter, turn temperature down to say 10 degrees during the night (effectively turning the thermostat off). (10.00pm-07.30am). The temperatures you choose are entirely down to you and what you find comfortable. Of course, if you live in a particularly cold climate, then adjust these temperatures accordingly. Hope this makes sense and good luck.
Worchester Bosch , the company who sells thousands and thousands boilers a year and yet cannot do CLEAR and PROFESSIONAL instruction video. There are thousands of customers who are single mums, elderly or just those who`s English is not their first language. They are certainly none of the wiser after this video. For a company that big.....it is a shame.
Just used these instructions to set my boiler. Success working fine now.
Thank you so much for this clear instructional video. It is priceless.
Hi, this is really great, thank you! My backlight stopped working and I can't get it to work again - is this a simple fix?
We ended up paying extra to have an old time clock fitted to our worcester boiler, the comfort controls are so complex to use , imagine old people trying to understand and use this , our gas engineer said it is a complete nightmare trying to explain this to people and we gave up in the end and had to pay an extra £200 to change! I completely agree with many of the other comments that this was designed by idiots, Worcester I hope you read this and suggest you go back to the drawing board and redesign with customer use in mind.
It's not just bad for older people - we are a couple in our late twenties and we are SO confused by this terribly designed thermostat! Going to buy a Nest to use instead
Totally agree. It is impossible to fathom. I will probably do the same as you. Hopeless design, Worcester!
Hi my mum is having a problem with greeenstar 4000 boiler rf 11 comfort control. Thinking of buying a timer (MT20) - can I ask did you buy a timer and how did you get on with it? thanks Mary
Thank you so much , the booklet does not give clear instructions to set the time so this is great :)
I would love a video on how the ECO mode works because it takes an age, and a lot of water before I get hot water out of the tap
Does anyone know what "on" setting does for heating? Does it ignore the time programme? I thiught i could juat set it to ON and then control via the thermostat. Very useful video by the way better than the manual...
very helpful much easier to follow than the leaflet that came with the boiler thank you
I think in my last house I had a Honeywell controller. Do you have a product that is simpler to understand, and doesn't work with either radio signals, nor the fingery clicky things
Jog shuttle. 😅
Very helpful video.thanks
Of all the millions of devices on the planet, no simple on and off button.
I have the RF II I'm still none the wiser. As with everyone else. All I want to do is set on/off times.
if it's the timer functions you want to set you can get to that by holding down the bottom right button for a few seconds and then a screen with different functions will pop up then just use the knob to move left and right on the screen and press the knob to access, it shows here at 1:44

Hi. Your video is so easy to understand but how do you set the Preheat to come on all day from 8am until 9pm at night, without pressing the on mode.
I entered 8am till 9pm in the DHW1 programme is this correct or should I be entering 9pm in the DHW2 programme?
Also selected Once, should it be on Auto?
Just had the boiler serviced and now the Preheat isn't coming on at 8am for some reason.
Any advise other than getting the engineer back in.
Thank you in advance.
Thanks, best then reading the operative manuel, very easy to follow and understand
Absolutely brilliant thank you
I have comfort + IIRF. My setting 1 is at 7.40 a.m. 20 degrees. My setting two is at 16 degrees, 8 a.m. Setting 3, 7.45 p.m. 21 degrees. At 9 a.m. the boiler is still on with low heat at my radiators. In other words is there no off time when set at auto?
Is Auto ok for hot water or on or off which one is more economical and efficient ?
My parents have this central heating clock and it will only come on at 23c would you be able to advise what’s wrong ?
Question - I have a 2 rf, why isn't there an option to set an "off" time?? From this video it seems that "auto" mode is similar to "on", with no Off time function my heating is permanently on, and all that happens is the temp setting is altered to lower. So my heating remains on at all times but will constantly cut in and out according to the temp setting. I'm concerned that leaving my heating in auto mode is going to increase my heating bill, and it would be cheaper to just turn it on and off, is this correct?
Fyi I live in a rental property so have inherited this heating system.
Great video, thank you. I have this boiler the compact. I would like to know how to set the timer for just one time. One start time and one switch off time (not 2 times in a day) Look forward to your reply
Thanks ... easy to follow and fixed the problems 👌
Thanks nice clear instructions!
My mam is 87 year old has just got a gree star comfort control for her boiler she just wants to turn in on an of she’s struggling can I get any instructions for her
How do I just switch it on and off when I want radiators on and off instantly?
I don't understand why with the Comfort II RF, you have no ON/OFF times for the heating...you effectively have to have it on from start to finish (albeit at different temperatures through the day). The Comfort I RF has clear ON/OFF periods...why can't I do this with my II RF?!?!?
All I want to do is set Timer 1 from 05:00 to 06:30, and then off until Timer 2 from 17:00 to 20:00! How can this be done?
I have same query. How to set off time?
@@fannumfox I think the idea is by turning the temp down to say 5 in the 2nd timed sequence the boiler will not be running so effectively it's off, but in a safe setting so as to prevent system freezing in extreme cold conditions
@@stewartclifton3068 thanks a bunch for your reply. I just realized 1 thing, when in setting 2 i set temperature at off, heating actually switched off st that time duration. What do u think its safe ? Or setting it at 5?
I have set the times for it to come on and go off. Set the correct date and time, but it seems to turn off randomly and not come on when it’s set. Any advice? When I went to set hearing times, did not show temperature just the times
How can I set my boiler to have the heating on constantly so I only have to adjust the temperature on the remote.?
Is there anyway to set the temp timer to come on only twice per day, like 04.00am to 05.00am then 15.00 to 1800 only those times.
I have the Comfort RF 1 controller. Does this work the same way.
This is very useful for me. Thank you Worcester!
I'm happy to read it helped :) - Aiden
I have comfort II. How to set off time for boiler? When selecting time? Its a pain not knowing when heating will go off? As i simply want to set heating 2 times each day. 3 hours morning and 3 hours evening. How can i do it? To set from 5.30-8.30 & 16.30-19.30???
I found this brilliant explanation in you tube comments* . I could not understand the Comfort II but I've got it now. Set the 1st time/temperature at your required temperature, then 2nd time (8.30) at say 10 deg (the boiler will not fire up if your house does not fall below 10 deg! It will stay off till the 3rd time setting. Set the 3rd time (16.30) at your required temperature. Set the 4th time at say 10 deg and again the boiler will not fire up. It will sleep peacefully until 5.30 in the morning. Press the button to ignore the
5th and 6th settings as shown in the video. Neither my heating engineer nor Worcester Bosch technical department could explain this to me - and the user manual makes no reference to this whatsoever. I could not figure out why the boiler was not "turning off" when I thought it should. Good luck, and you will see - it wont be using any gas during the 10 deg period (of course if the room where your thermostat is gets colder than that (!) you'd have to set a lower temperature - say 5 deg - which is what they recommend if you go on holiday - it just keeps it in frost protection mode. Not necessary to go any lower than that.

* Basically this is a 24 hour temperature profile system allowing up to 6 programmable time zones set at given temperatures for that period. There is no on or off setting as such as this will depend on the temperature setting. If you want it off during the day, set the desired temperature to zero. Most working people will want a lower setting overnight, say 16C, then up to 20C when they are getting ready for work, then low or off during the day, say 10C, then back up to 20C for when they return from work until going to bed; hence four temperature time zones. The controller, however, doesn't cater for retired or non working people at home 7 days per week, for this you need to program mon-fri and sat-sun the same. The override feature allows you to jump to the next zone if you arrive early from work for example. The Wave allows you to do this remotely via an app. I guess this system is a set and forget controller with holiday override. Alternatively the lower spec unit just gives three on/off daily settings. Only concern is when the battery dies or if this unit malfunctions. This being the issue with complicated controllers is all types. The Wave needs constant wifi for example and access to an iPhone or iPad.
Hi brilliant video, very useful, but please can you tell me why I need to set the different times for the hot water, when I would rather be able to use it at any time? Also, I find the water too hot, how do I change the temperature of this please?thanksI have a new Greenstar Comfort II RF prog
Hi Berverley, I wondered the same about the hot water, I thought it would be available 24 hours a day. To change temp of hot water just turn the right hand knob down a number. Ours is set on "e" for economy, but you can go up to 6 or down to 1 or min.
Hi Beverley, thanks for your feedback. Hot water will always be available on demand for combination boilers, the timings would only be applicable to conventional boilers which use a cylinder. Please refer to your boiler installation manual for information on adjusting the temperature of the hot water.
Do we have to put the room controller on the wall? I prefer it mobile.
Why do you need to select on/off times for the water. I thought a combi boiler supplies hot water on demand i.e when you turn on the hot water tap the boiler kicks-in and heats up the water.
MY THOUGHTS EXACTLY! Any updates from anyone who might know?
I think that part is only relevant for old non-combi boilers
These boilers have a pre-heat function so (in theory) you will get hot water at your taps faster then just heating on demand. In reality it is mostly a gimmick that just wastes gas and you're probably better off just setting it to "off" where it will act like a conventional "on-demand" combi boiler.
If performing the "Unpairing" function through Installer mode, will this stop the unit from emitting radiofrequency radiation? Thanks.
How do I use the controls that are on the boiler itself (not the unit that the video's about)? In particular, I want to know how to turn off the eco setting. (I'm pouring away a lot of water waiting for hot water to come out of the tap.) There's a set of three buttons on the boiler. One of them is the eco button, but it seems to be linked to the other two. Can I just press the eco button to turn of the eco setting, or will that have knock-on effects? I have a Worcester Comfort II RF.
Thank you for your comment. The two controls, boiler and Comfort II RF, work in conjunction with each other. For easier control, press the ECO button on the boiler until it shows either 'Preheat' or 'ECO with a clock symbol', then use the hot water settings on the Comfort II RF to control the preheat, either Off (no preheat), Once/Timed (Preheat follows the programme) or On (Preheat on all the time).
We will be happy to send an instruction manual to you for your Comfort II RF control, please get in touch with our contact centre on 0330 123 9339 or alternatively send an email to service.mailbox@uk.bosch.com and we will just need to take a few details to send the manual out to you. Thanks, AW
Thanks. So the Comfort II RF is the programming device, not the boiler. And it seems I can't simply turn the Eco setting on and off at the boiler; I have to program it so that the programmer turns it on and off. Similarly it looks as though I can't adjust the temperature of the heating directly; I have to program the programmer to do that. If I want hot water now or a change in temperature now, I first have to have a plan for the whole day - or the whole week. Have I got that right?
We believe that it would be best to discuss this directly with you. Please could you contact the technical department directly on our free number, 0330 123 3366, and our advisors will talk through all the settings on the Comfort programmer as well as the boiler. Many thanks, Worcester
Why do you need to set the hot water times as the boiler only heats the water you draw down with a tap? What does setting hot water times achieve? As there is no tank with a Combi boiler.??
My programmer is currently on a timed programme for heating. How do I cancel this and get back to manual control for summer months?
Thanks mate very helpful 🙏👍
Cam anybody explain why the heating seems to be in some sort of limp mode ?, my boiler picks and chooses when it want to fire up quickly or slowly?
Boiler has been fitted correctly and system was flushed . I just don't understand
So, we have a remote counterpart, but can't find it. It seems that the main comfort controls won't override that remote, though. So the boiler is completely off and can't get it back on? Wireless room stat is what you called it.
Hi Nathan, I would recommend giving our tech team a call on 0330 123 3366 as they may know a work around. It sounds as though you may have to look into a replacement wireless stat, hopefully the tech team can help you get this sorted though 😊🤞 - Aiden
is it better to have the hot water function on permanently or to set times?
Hi Sarah, The hot water side of the comfort controls range (when fitted to a combination boiler) is to time the pre-heat function of the boiler. This effectively keeps a small volume of water within the heat exchanger hot. This will ensure that hot water is delivered almost instantly to the opened outlet.
If you are not using preheat, the boiler will be in ECO mode and the hot water will be heated from cold. A slight delay should be expected before the hot water is at full temperature when the boiler is operating in ECO mode. By selecting ECO mode, less gas will be used as energy is used only on demand.
Regardless of the way the boiler is used (Preheat or ECO) a combi boiler will work when the tap is opened. Hope this helps, EH
@@WorcesterBoschHeating thank you, yes it does

Hi Ray, please find below a link to download the manual.

Thank you now sorted.
That page is a 404

How do you use the thermostat for the 1 RF boiler? I have set timers etc, but the thermostat goes on the room temp rather than what I want?
A thermostat will go on room temp, that’s the idea, if the room temp matches or is above what you have set the heating will stay off, if the temp drops below the heating will turn on.
The RF1 shows the current room temp on it, to adjust just twist it, it will show the new required temp and flash whilst contacting the boiler, if your going hotter then you will see a little flame icon appear, this means your boiler has received the request and is operating
Don’t forget all the timer does is turn the boiler on and off according to the times you have set, the thermostat still controls what temperature you require, sounds like you need to make sure you are using the timer function and not the always on setting
@@djhatstand7312 Hi just responding back to your message as my boiler says on but there's no heat coming out of it. Do I need to turn my thermostat high for it to stay on?.

The Saturday and Sunday you set separately to the Monday to Friday 😁
Found this video easy to follow. Much better than the booklet!! Only thing is how can you override the timings if you want the boiler to stay on longer at night.?
Turn to "on" or "once"
Why is my comfort 11 RF showing the frozen symbol when I've selected Off for my heating ? Still require the hot water. Please can you explain
Hi Diane, the reason the Comfort II shows the frost symbol when the heating is set to off is that it is effectively running in frost protection mode only. This does not impact the hot water timings. Please let us know if you have any further queries
I HATE this system. I'm not in control. Whatever happened to On and Off? I have to set the temp very low so it doesn't come on randomly while I'm out.
Also I don't go to bed til late and I've yet to find out how to set the control to go off AFTER midnight. I've tried 00.30 but it won't stick. Anyone know?

Thank you for your comment. Can you please provide us with the model of boiler that you have, we will then be able to answer your enquiry. Thanks, AW
The boiler is a Greenstar CDI Compact.
To be more precise it is the 32 CDI compact
Hi Terence, as this boiler is a combi boiler whenever a tap is opened the boiler will fire up to satisfy the demand. The on/off/timed functions on the programmer are in relation to the pre-heat function. Let us know if you have any more questions, or you can call our team on 0330 123 9339. Many thanks, Worcester
