I have a combi boiler. When I remove the thermostat/control unit located in my living room I see two wires going into a chocolate block style electrical connector labeled NO and COM. Would this setup be suitable for a Nest Thermostat?
Thanks for posting in the Google Nest Community forum. I'd like to know more about it. A few questions: what is the make and model of your system? Also, in what country are you located?
