Help. Have a Danfoss room thermostat for underfloor heating that no longer seems to be programmable. Want to replace with a smart thermostat. Got a ProTouch Smart.
The old Danfoss had 3 wires connecting. Grey into (N)eutral, Black into NC/Normally Closed and Brown into (L)ive.
The new Protouch has Neutral, Live, NO/Normally Open and COM contact points. Ie is does NOT have a NC contact.
I assumed to wire it, it would be Grey/Neutral, Brown/Live... and the Black into either the COMM or the NO. Whilst the thermometer powers up and connects to WIFI ok, it doesn't trigger the boiler to heat the room. I will call an electrician in, but posting here in case there is an obvious solution. Thanks in advance.
