I have a 2 wire thermostat (heat only). Simply connects the circuit to the zone valve. When it closes it turns triggers the end switch of the valve which kicks on the circulator. Sounds straightforward.
Well I want to add a Wifi Thermostat. All the ones I looked at need a C wire. (For power) What is the best way to go? Can I just add a single wire from the 24v transformer to the thermostat? will it use a ground from the other 2? (assuming I locate the one that is ground)
