A self-operating damper device constructed to be installed in open ended furnace duct boots which terminate in room registers, said device operating in parallel with multiple units as part of a forced air heating and cooling system for the purpose of controlling and regulating the flow of the heating/cooling medium to individual rooms, independently and simultaneously through opening and closing of damper plate. Self-operating damper means include damper housing with rotatable damper plate hving an integral shaft with attached end pulley, said pulley being interconnected with motor means through drive belt which encircles both the damper pulley and motor pulley with drive motor being controlled by switch means operated by rotating cam on motor output shaft, said motor responding to commands of room thermostat which influences both motor means and combustion cycle of combustion means.
