smart thermostat always on
I've just unpacked my wired starter kit with TRVs and figured easy. But the Smart Controller seems always to be on. I wired it into my combi boiler but the CH was on whether I set the smart thermostat to 9deg or 25deg. Pulled it back off again and attached wires, and I find the Smart Thermostat always has COM connected to NO and never connected to NC. I've tested this using my multi-tester and waited minutes when changing the temperature from high to low. Also used the app to change the temperature, no effect on wiring.
Hope this is clear, I figured this was an easy swap for the old wired thermostat to the new wired thermostat but nope. Any help is much appreciated!
