I have a Miller CMF 2 80 gas furnace. 3 years old. It has a UT electronic controls 1018 series module. My thermostat wiring is just 2 wires. How can I best add a "C" common wire to supply the new thermostat? I notice that there is a "C" connection on the control module...can that be used?

Thanks much!

A nest will rub off a 2 wire FYI, and generally if the board has a C yes that will work for a common. You can check with a voltmeter as well on that c terminal to be sure

If there is no common you're only other choice is adding a 120v → 24v transformer to the circuit.
