Hi Pat,
Thanks for the quick reply. I did jump the red and white at the
thermostat and the heat does activate, Iâ??m also getting power to the C wire
when I ground it at the thermostat. Iâ??m figuring that the lack one of the
other wires, A/C or fan, may have something to do with the unit not working. If
the C wire is common shouldnâ??t there be another wire to complete the circuit
to provide power to the unit, maybe the red?
Best,
Bob
