Abstract
An integrated damper control system is used with a gas fired appliance including a gas burner, a flue and a damper for selectively opening the flue. The damper control system comprises an appliance control including a programmed processor for controlling the gas burner and a communication interface device. A damper control comprises a programmed processor for controlling the damper and a communication interface device for communication with the appliance control communication interface device. The damper control programmed processor is programmed to selectively open or close the damper responsive to status of a damper request register and to control status of a lockout register to indicate status of the damper. The appliance control programmed processor is programmed to control status of the damper request register responsive to a call for operation of the gas burner and to operate the gas burner only if the lockout register is set to unlock.
