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.
