Abrégé

A system and method to control environmental parameters of predefined zones within a structure. An embodiment of the system uses damper assemblies that are entirely wireless as a result of energy capturing devices which convert air flow within the HVAC system ductwork into electrical current and a wireless control module that remove the need for hard-wiring for power or control. Still further, an embodiment of the system uses wireless components to monitor the environmental parameters of a structure's zones, process and communicate necessary zone adjustments, and actuate system components.

Abrégé

A system and method to control environmental parameters of pre-defined zones within an environment using an electronic controller. The system includes a non-proprietary electronic controller which enables a weighting value to be assigned to each zone within the environment. The electronic controller also detects any zone service calls from sensor devices associated with each of the zones and determines a cumulative weighting value in response to the detected zone service calls. The electronic controller selects an equipment staging combination from at least two possible equipment staging combinations in response to thermal capacity, and an air handler stage is selected in response to at least the cumulative zone weighting value.

Abrégé

A small duct high velocity (SDHV) damper assembly. The SDHV damper assembly includes a generally tubular damper housing having first and second ends, wherein each of the first and second ends is adapted for insertion into associated high velocity ductwork respectively. A damper blade or an expandable damper member is situated within the damper housing to restrict flow in the damper housing in a controlled manner.
