Abstract

An HVAC control system provides a central controller that controls registers/vents which capture energy of air flowing in the duct system and convert it to an electrical current that is stored locally in energy storage units in the register/vent. Further, wireless communication between the central controller and the register/vents alleviates the need for wire runs and maintenance. Use of unique register identifiers allows the central controller to individually control each register based on user settings. As such, the user can install one or more registers and individually control one or more registers for desired temperature control in each zone. A wireless network allows user interaction with the central controller via a Web-page utilizing a Web browser on a PC that wirelessly connects to the central controller (e.g., via a wireless network). The register/vent combination is preferably and all-in-one unit that slides into the air duct opening in each zone.
