Issue with Tado TRV not working
I've been pulling my hair out trying to sort this. I have the Tado smart thermostat which works fine. I then added the Tado TRV, which was setup properly without any errors.
The issue is that if I increase temp on the TRV, it does NOT activate the boiler/heating. I have added a further 2 TRV's so 3 in total and all have the same issue, which rules out a faulty TRV.
If I increase temp on main thermostat, the system works as expected and everything heats up. This also rules out a faulty main thermostat or boiler.
I also have the ext kit if that makes any difference. Tado have confirmed my wiring is correct.
