I have just added a TRV to my Tado system with a master room thermostat in another room. To date the master thermostat has controlled the heating very well. If the temperature falls below the set temperature in the room with the TRV the boiler is fired up heating the whole house even though the the rest the house is at or above the set temperature. This is not a smart control wasting energy for the sake of one room. I am trying to to stop the room with the TRV from over heating if not occupied so want the TRV limit the temperature in that room. I would like the TRV to operate in slave mode so that it could limit the temperature but not be able to fire up the boiler and heat the whole house. Is this possible?
