    Pair Honeywell DT90a with DT92 relay box??

    What do you mean by ‘Learn the new thermostat’? Me, or the relay?

    Pair Honeywell DT90a with DT92 relay box??

    Oh dear. Thanks! One more question- if I return it and buy a new DT92 instead, will I be able to pair the new thermostat with my existing relay box? Or will it only bind with the one it comes with in the box? Am trying to avoid having to get a plumber to come out!

    Pair Honeywell DT90a with DT92 relay box??

    My DT92 thermostat wasn’t working, so I ordered a replacement. I seem to have accidentally bought a DT90A thermostat, which doesn’t have a relay box! Is it possible to bind this thermostat with my existing relay box? I’ve tried to follow the instructions on youtube given to bind a thermostat...

    honeywell RF DT92 thermostat not working correctly

    That's correct. It does seem to fire up the boiler if I set it to be higher than the ambient temperature. But I feel the floor didn't actually get hot once the boiler fired up! If set to go on below 21.5, it shouldn't be ever displaying the fire symbol at 22.0 - even though I think this is...

    honeywell RF DT92 thermostat not working correctly

    nope.... But tbh, I'm more concerned that it seems to be turning on at the wrong temperature. And when it displays that it's on, I don't actually think the floor is getting warm!!

    Also, even if it was in a heat trap, it shouldn't be turning the UFH on at 22.0'C, when it's set to go on below 21.5'C Also, it seems to always be 22.0, even though the room feels a different temp...

    honeywell RF DT92 thermostat not working correctly

    Thanks very much D, The thing is, I haven't moved the thermostat. It's been in this same location for over a year! It's just acting really odd. (It's not above a radiator; it's in the kitchen where the UFH is)

    honeywell RF DT92 thermostat not working correctly

    Novice, I paired the two devices as described. But.... the thermostat is still acting up. I believe it's misreading the room temp (I feel cold, and it's showing 22.0'C) and the fire symbol is appearing at a temp higher than I've set. Do you think I need to buy a new thermostat? Anything else it...

    honeywell RF DT92 thermostat not working correctly

    Will check it out, but it strikes me as a strange coincidence that it got goosed just after the switch was changed! Will go on a hunt under the house tomorrow.....

    honeywell RF DT92 thermostat not working correctly

    It's not near the boiler. Will have to look in the basement when it's daylight! Will revert in the morning. Thanks so much! (What will I do if it is flashing red?)

    honeywell RF DT92 thermostat not working correctly

    I'm not actually sure where this is. The manifold is in a basement under our kitchen, would it be with that?

    honeywell RF DT92 thermostat not working correctly

    I hope someone can help. A few weeks ago, the fuses blew in my house, it turned out that water was leaking on the switch in the manifold for the underfloor heating, and this was replaced. However, since then the wireless thermostat is just not working as it should! -Firstly, it is always seems...
