Abstract
A damper system is configured for installation in ductwork including a duct supplying conditioned air through a register boot to a register vent. A damper is movable between a closed position and an open position. A control module includes a control module housing, a controller, a power supply and a transceiver. The controller monitors a remaining energy level of the power supply and transmits a first low battery message via the transceiver when the remaining energy level drops to a first energy threshold. The controller instructs the damper assembly to move to a predetermined position and to transmit a second low battery message via the transceiver when the remaining energy level drops to a second energy threshold.
