Automatically Balancing Register for HVAC Systems

A system for controlling an HVAC system of a type having a plurality of HVAC vents, each HVAC vent disposed in a corresponding location in a building, the system comprising a corresponding plurality of intelligent controlled registers, each intelligent controlled register associated with a distinct one of the HVAC vents, each intelligent controlled register including:

• a motor coupled to a controllable damper;
• a temperature sensor;
• a wireless transceiver for communicating with at least one other of the plurality of intelligent controlled registers;
• a controller coupled to the motor, the temperature sensor and the transceiver;
• a power source coupled to the motor, the transceiver and the controller;
• wherein the controller is configured to carry out processes including:
• obtaining data from the temperature sensor and, via the wireless transceiver, data from at least one other of the plurality of intelligent controlled registers;
• using the obtained data to automatically determine a desired operation of the damper;
• and
• driving the motor to cause the desired operation of the damper.

A method for controlling an HVAC system of a type having a plurality of HVAC vents, each HVAC vent disposed in a corresponding location in a building, the system comprising a corresponding plurality of intelligent controlled registers, each intelligent controlled register associated with a distinct one of the HVAC vents, the method comprising:

• obtaining data from a temperature sensor and wirelessly obtaining data from at least one other of the plurality of intelligent controlled registers;
• using the obtained data to automatically determine a desired operation of a damper;
• and
• driving a motor to cause the desired operation of the damper.
