Abstract
The invention is directed to a control system for an air delivery system having a supply duct through which air is delivered into at least one independently controlled zone or room through an air delivery register. The control system for one zone or room includes a wireless air flow control thermostat to transmit a wireless air flow control signal output to an electrically powered and electrically self sufficient register air flow control unit that controls the flow of the air through the register in response to receiving the wireless airflow control signal output. The electrically powered and electrically self sufficient register air flow control unit includes an electrical generator to provide power in response to flow of air through the register from the supply duct. The generated electric power is delivered to the register air flow control unit to thereby maintain the register flow control unit electrically self sufficient and free from the need of any outside electrical power source.
