Is this 2nd Zone Setup possible?
Picture is the Boiler set up as of now. Downstairs is a controller to a wireless Honeywell thermostat, with TRV on radiators, Upstairs was the same but replaced the controller with extension kit, with all radiators having Tado valves and wireless thermostats in two bedrooms.
Am I right in saying that I could just replace the Downstairs controller with a wired Tado thermostat, which can be now changed to be Zone controller? And do similar to what I have upstairs with Tado radiator valves and Wireless thermostats in main rooms?
Can anyone give any clarity if what I think possible actually is?
