I'm still trying to get my head around central heating zones. I understand the practicality and that each zone has its own thermostat or programmer. But someone asked me today, how is having a separate thermostat upstairs any different than setting all the upstairs TRV's to 3 or 4??
Wasn't really sure on the best answer to this. Obviously a separate programmer makes sense but is it really worth it just having a thermostat controlling that zone?
