When installing in a single transformer system, keep the jumper wire between the and c screws. When installing in a two-transformer system, use the common from the cooling transformer to connect to the screw and remove the jumper wire between the and c screws. hree AAA alkaline batteries can be used to power the comfort control for armchair programming only. o prevent the comfort control and heating/cooling system from shutting down due to lack of battery power, it is not recommended that the comfort control be solely powered with the three AAA batteries during normal system operation. When using batteries, make sure positive and negative terminals are oriented correctly, as marked on the device. See ig. 6. attery Power (ptional) CAUIN Equipment or Property Damage Hazard. Using battery power only may not provide adequate power to comfort control and can cause damage during freezing conditions.
