Abstract
A controller for an environmental control system, e.g., an HVAC system, that includes a power circuit for providing power to some components of the controller across a variety of HVAC systems. The HVAC controller of this disclosure may include components with power stealing circuitry to run components. However, because the diversity of HVAC system loads and configurations, some power stealing circuitry may not function as desired to draw the power for operation in some systems. The universal AC power circuit included in the HVAC controller of this disclosure may provide power to components of the HVAC controller when the power stealing circuitry may be incompatible with certain HVAC systems. In this manner, the universal AC power circuit may allow the HVAC controller of this disclosure to be compatible with and operate to control a wide variety of environmental control systems.
