SELF-SETTING CIRCUIT FOR AN HVAC CONTROLLER

摘要

An HVAC Controller may include a first sub-assembly and a second sub-assembly capable of releasably engaging the first sub-assembly. The first sub-assembly may include a first housing and a printed circuit board having a controller for providing one or more control signals, where the printed circuit board may be secured relative to the first housing. The second sub-assembly may include a second housing, a power source, one or more output terminals, and a second printed circuit board. The second printed circuit board may be secured relative to the second housing and may have circuitry thereon that is powered by the power source and configured to receive the one or more control signals from the first printed circuit board. The circuitry of the second sub-assembly may set output terminals thereof to a predetermined state when the first sub-assembly is released from the second sub-assembly.

主权项

1. An HVAC controller for controlling one or more HVAC components, the HVAC controller comprising:
a first sub-assembly comprising:
a first housing;a first printed circuit board having a controller for providing one or more control signals, the first printed circuit board secured relative to the first housing; a second sub-assembly configured to releasably engage the first sub-assembly, the second sub-assembly comprising:
a second housing;a power source;one or more output terminals; anda second printed circuit board secured relative to the second housing, the second printed circuit board having circuitry powered by the power source and configured to receive the one or more control signals from the first printed circuit board when the first sub-assembly is releasably engaged with the second sub-assembly and to provide one or more corresponding control signals to the one or more output terminals of the second sub-assembly, the circuitry of the second printed circuit board further configured to set the one or more output terminals of the second sub-assembly to a predetermined state when the first sub-assembly is released from the second sub-assembly.
