On my furnace there is a wire that is labeled C/Common. But at my thermostat there is no common wire.
Wires on furnace control panel:
W - White
Y - Yellow
G - Green
C - Common
Wires at my thermostat:
W - White
Y - Yellow
G - Green
Rh - Red
Rc - Blue No power(see below)
NO C - Common
Also the Rc wire has no power. I tested with a multimeter positive lead on Rc and negative lead on Y.
Can anyone help me?
