It's the same panel as my Worcester junior

Couldn't agree more, this has caused no end of a problem for my elderly folks

@@rawfire9112 Ditto. My mum has bought an electric fan heater which is costing her a fortune.

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!?

@@rawfire9112I’m 32 and think it’s a pile of sh**. I moved into a house with a Worcester boiler and have this thermostat. It’s awful.

Absolutely agree , all i want is my heating to come on and off on a preferred time set without jumping through hoops

JamesBurrT

I thought it was just my plumber not leaving the info

@@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

I hate the Boiler

Ah the good old days eh. Don't make them like they used to

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

We're glad the video was helpful, thanks for your feedback!

Same for me too

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 👍🏻

I'm happy to read it helped :) - Aiden

I'm thinking the thumbs down might be because the whole set up is simply not good enough!

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 KZfaq, 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.

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.

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.

Jog shuttle. 😅

Thanks for getting in touch. Please could you give our team a call on 0330 123 9339, and we'll assist with some troubleshooting, thank you

Mine has a 'once' setting but it doesnt do anything, the whole system is very buggy.

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

@@David.L291 how can I turn off heating before that time, like is there a switch to turn off completely? I am new to this boiler, I have 36cdi

Hi Rosie, I found out how. You need to hold down the "Menu" button and the "Return / back" button at the same time for 3 seconds.

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

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

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.

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 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

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?.

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

Thank you now sorted.

That page is a 404 My plumber told me 'the batteries would never need replacing' presumably the battery lasts longer than the boiler

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

Do you have the Automatic mode selected and is your System Time set correctly?

That happened to me after a powercut and I found it was the clock. Once i reset the clock to the right time it was fine.

How did you get this off

Jason Cooke select on with the select button by the radiator symbol on left of screen.

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

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.

My 550 cdi I would turn the left hand knob anti-clockwise until it clicked and/or switch heating to off on the roomstat.
