I have a CCC2 controller that originally showed only COOL and Fan. I flipped the Furnace switch in the AC control board and now Fuurnace shows on the CCC2and the Furnace now runs when selected and the thermostat selects Furnace BUT now the furnace contact is set AND both Furnace is activated correctly and the Air Conditioner cooling is running. No other switches are set in AC control board. I only have one zone. I there some other switch that needs to be turned on to shut off the AC.
