I have a hot water heating system , the thermostat uses 12/2 wiring what thermostat
I am looking for a new thermostat for my home heating. I have an oil burner that uses water in baseboards ( I believe hydronic) the current theromstat uses a 12/2 wire that goes to it. This wire has a black, white and nuetral. The current thermostat is very straight forward and these wires screw to the back of it. I want a new thermostat, preferably programmable. What can I use? All my searches of this type of wireing only come up with electric heating systems and I do not have this?
