I Purchased the Honeywell WiFi Prog Thermostat to replace my Round Digital Honeywell Thermostat. I have separate Heating and Cooling (Heating is a Weil McLain Boiler for Hot water baseboard and Hot water(no tank) and Cooling is a separate unit that was added later.)
RC Cool R Heat W Heat Y Cool G Cool
3 wires from AC unit and 2 from Heater.
If I were to go the separate transformer route to power the thermostat, where would I land the 2 wires?
