Honeywell T3 wireless programmable roomstat

How to programme and operate your thermostat

[suzanneweekes]

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 YouTube. 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

[aniamlodzianowska]

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

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!

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

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

[SuperMeenusingh]

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

[JunglistBaker]

Very helpful 👍🏻 easier than reading the manual

[PhilReilly]

Many thanks, much more comprehensible than the manual.

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.

Really helpful and easy to follow, thank you!

[nubiaortiz]

Thank you for demonstrating the copy mode!

[nataliepowell]

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

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?

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

[patrickodonohue]

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

[michaelwarde]

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

[jaswinderupaul]

Excellent tutorial!
Thank you so much

[suejf]

Thank you so much. That was I looking for.

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?
