I have recently moved into a property with a new (less than 6 months) central heating system and a Baxi Combi 105HE boiler. TRVs are fitted throughout, but although an aged room thermostat (presumably from the previous system) is fitted it is not connected.
The Baxi will accept a room thermostat, so is its ommission likely to be due to the TRVs, a decision by the installer just not to connect it or another reason ?
