Can someone kindly confirm if I’m correct. I just had Drayton Home Multi Zone Kit 1 installed in my house. For the smart thermostat to work properly, am I right to say that the radiators where I’m gonna place the smart thermostat needs to have smart trv as well or normal TRV will do? Say the smart thermostat will be place in the lounge, radiator in the lounge needs to have smart trv as well? Thanks!
