White Wire for Heating System (If so equipped)ĢThe W terminal is for heating, including the heating for gas furnaces, electric furnaces, boiler systems. Finally, it will feed it with 24 volts, provide power to the thermostat, and when the thermostat calls for heating or cooling, provide everything with control power. That will power the relay, contactor, or complete the circuit in the circuit board.
