Abstract

A HVAC controls system for zone controls that is comprised of one or more Wall Sensor Units (WSU) and zero or more Damper / Register Units (DRUs). The invention is a low networked cost solution for residential and light commercial that is easy to install in new and existing building. The WSUs detect, log and use occupancy data to predict where in a building HVAC conditioning is needed and to save energy where it is not needed. The DRU use shape memory alloy wires to control the opening and closing of a damper plate with very little power allowing batter operation.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application is a continuation of U.S. patent application Ser. No. 12 / 284,795, filed Sep. 25, 2008, now pending, which application claims the benefit of U.S. Provisional Application No. 60 / 997,426, filed on Oct. 4, 2007, which application is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION

[0002] The technical field of this invention relates to zoned residential Heating Ventilation and Air Conditioning (HVAC) and lighting controls that employ embedded systems and wireless communications. HVAC systems use a large proportion of a building's energy usage and need to be optimized for both environmental and economic reasons.

[0003] There is a long history of invention and research associated with HVAC technology. Programmable Thermostats: Programmable setback thermostats that can be set by the occupant for set point, reset point and schedule have been available on the market for a number of years [EnergyStar]. In spi...
