Is there a scenario where the Boiler will fire with all TRV's closed
I'm thinking of switching from Nest to Tado, the reason being is that I end up with livingroom at temperature where the Nest stat is fitted and all the others colder because the boiler is turned off when the living room is up to temperature. The radiator in the living room being the one with the fixed lockshield valves.
so I'm thinking that I would fit Tado smart TRV's to all radiators including the living room. Fit a Tado Smart Thermostat in the Living Room, and then each room calls for the boiler when needed.
I'm reading because the living room will have a Smart TRV and Smart Thermostat, you can choose which one is the master for that room, so I would have to think a bit about which one I would choose.
So in this scenario which device in the living room should you select to be controller for that room?
And also, with a setup with eight Smart TRV's and the Smart Thermostat, is there a scenario here which I could find the boiler firing with all the TRV's closed but the Thermostat is calling for heat?
It's a combi boiler, no external bypass.
