House Thermostat vs Room TRV

cpjames2000

Hi all

Quick newbie type question: If the thermostat is set to a low temp not requiring heat from the boiler but a trv is set to a higher temperature, I assume that the boiler fires to heat the rad requiring it or is it overridden by the house thermostat?

Thanks

Hi Chris,

If the TRV and Thermostat are in the same room you can specify from the room's settings menu which you want to use for measuring the temperature.

This being said, the temperature set point (and schedule) is not per device but per room. It's like having a thermostat in each and every room. The TRVs just add the option to stop heating a room while you are heating others.

Hope my mumbling was clear enough 😄

Regards,

will a Tado radiator stat,in a different part of the house, when calling for heat actually get that heat?

Yes. When heat is needed in any room with a TRV, the TRV will open and it will signal the boiler to turn on. So it may also cause other rooms to heat if they dont have a smart TRV.

Thanks Andrei, yes answers the question perfectly.. The room with the wall thermostat doesn't have a rad in it as its a through room. So if for example a rad trv in a room is requesting a higher temperature than the wall thermostat then heat will be requested from the boiler to meet that higher rad temperature requirement.

I don't think that answer really touched on the point of whether or not the Thermostat which controls the boiler has primacy over any other.

If a Tado thermostat (boiler control) is in a hallway and set at a low temperature (or frost protection), will a Tado radiator stat,in a different part of the house, when calling for heat actually get that heat?

Thanks, that makes sense.
