What furnace temp settings? Have an 04 Carriage with a Carrier AC/H unit and am attempting to set the furnace to run instead of the Aux heat on the AC. Set Wall thermostat to 80+/- and the hand held control to 77, furnace kicked in. When I lowered the W/T to mid-upper 70's, furnace shut off. What one controlls the furnace what temp setting would you set for 70-75 degrees?
