I really want to thank you. The Honeywell instructions are really non existent. I didn’t understand any of it and had inadvertently set it to 16 degrees. After a chilly night, I was just considering what I could possibly do when I found your KZfaq. Brilliant. I am so grateful.

this was the third video I've watched and it was the best as you described everything very clearly - thank you

If the thermostat is in AUTO, if you raise the temp with the plus button (e.g. 25degrees when the AUTO mode is set to 23degrees), il will only run for 1h, as you can see on the screen on bottom-right side. I'm pretty sure I've seen this in other videos. Correct me if I'm wrong. I think only the newer T4R version can be modified to run more than 1h if you override the temperature in AUTO mode.

THis was the best explanation , thank you. I can now set the thermostat and hopefully stop freezing. Very very helpful.

Very helpful 👍🏻 easier than reading the manual

Installed yesterday didn’t have a clue how to adjust heating till I watched your video I just set it to manual found it easier thank you

Thank you for these instructions. I haven’t been able to figure out how to turn the heating during the on-timed period.

Thank you so much, I've just move into a new placed and I had no idea how to work it. Bless you, you wonderful and beautiful person!

Really helpful and easy to follow, thank you!

Thank you for demonstrating the copy mode!

Thank you for uploading! Really helped as had just upgraded to this and couldn’t figure it out 😅

THANK YOU SO MUCh!!!! This has been a Lifesaver!!! THANK yoy!!!

So helpful! Thank you for doing this

Excellent tutorial! Thank you so much

Thank you so much. That was I looking for.

Thank you thank you thank you! So easy to understand 😊

Thank you! Life saver!!!

Many thanks, much more comprehensible than the manual.

very helpful guide easy to follow

Very useful, much better than the pathetic small guide that came with the thermostat. I'm intrigued that when you set up day 1, it seems to jump to day 3, and not day 2. Mine does that and that is what happens in the video (unless I'm mistaken). I think this is an error with the device. Anyone else noticed this?

That was a master class on how to set the on/off times and temperature. Thank you. My problem is, I can't find how to set the clock. When I go to menu the only option are on/off/temperature, I cannot find the clock. Help! I completely agree with others on here, the manual is absolute rubbish

The honeywell link to the downloadable manual is broken, I don't know how to use a QR code, the printed quick set up leaflet didn't work for me. this has been a lifesaver. Inwssitting hear with a new central heating system freezing. Thank you

Why does my handset keep flashing when pressing the buttons asking for year month day time go through it all then it goes off again eventually it does come on .After a couple of hours starts flashing again.We always have it on manual.We have had trouble with batteries not laying flat in the handset which causes it to haywire it's going worse lately .

i have pressed something accidentally and it is now showing "OFF" and i cannot find how to switch it on again would be grateful for your help

Very clear, thanks. Can I reset the clock when the clocks change twice a year without having to repeat all the other steps?

Simples ,many Thanks...

Are you sure that P2 and P4 are for when we want the heater to be off? How can I program the 4 programs for my house to be at 21degree from 6am to 23pm and for the heater to be off between 23pm and 6am?

Brilliant.

I would like to work the thermostat manually so I can turn it down low at night. The sound of the pump keeps me awake at night. Am I able to do that? The manual is useless.

How do I sync it to the boiler as the red light is flashing on the receiver which tells me it's not synced

I cannot find copy on my thermostat and it separates monday /Friday from sat /sun

Brill. My issue is though that my thermostat has disconnected from my baxi boiler. The receiver is flashing red. The boiler is working independently but will be costing me a small fortune! I do not know how to reconnect! Can't see a reset button on thermostat and the reset button on the boiler isn't working :(

Thanks, I looked up the guide and it's terrible it doesn't cover any of the details you mentioned

My unit is just flashing 20 after replacing the batteries, none of the buttons are responsive, does anyone know how to restart this unit?

Thankyou : )

I’m just trying to put it on right now 😫😫😫

You have not mentioning this NEEDS a battery. We did not know and our boiler was constantly on our room was extremely hot.. I had to turn our boiler off to stop it. Eventually I realized it must have a battery BUT WHAT A JOB getting in there is NOT a arrow or any indication of a compartment The battery compartment IS NOT OBVIOUS. This video is good showing how to but it DOESNT mention it will need a battery change and what happens when it does. I guess it stops on whatever mode it is in when the battery fails either ON OR OFF. Ours failed in the on mode and when we came in it was UNBEARABLE. Im glad my dog was NOT fastened in that room. I DREAD to think about this happening

very helpful as the user Manuel is very confusing and in poor English

Far too complicated can I get a written guide?

Much to fast.
