Abstract: A device for detecting a wire configuration connecting a thermostat and HVAC equipment includes fan controller circuitry, AC controller circuitry, switching circuitry, and processing circuitry. The fan controller circuitry is configured to operate a fan unit of the HVAC equipment using a G pin in a first wire configuration and using a K pin in a second wire configuration. The AC controller circuitry is configured to operate an AC unit of the HVAC equipment using a Y pin in the first wire configuration and the K pin in the second wire configuration. The switching circuitry is configured to refrain from electrically coupling the Y pin and the K pin in response to a deactivation signal. The processing circuitry is configured to determine the HVAC equipment is in the first wire configuration in response to determining the AC controller circuitry receives power while outputting the deactivation signal to the switching circuitry.

Abstract: Power stealing circuitry to provide power to a controller for an environmental control system. The power stealing circuitry may include a first circuit, to steal power when a load for a stage is switched off, e.g. de-energized. The power stealing circuitry may include a second circuit, e.g., a power trickle circuit, to steal power when the load is switched on, e.g., energized. The load may include a furnace, electrical heating element, heat pump, humidifier, electrostatic filter, air conditioning unit and so on. In some examples, the environmental control system may have one or many stages, each with a separate load. The controller may include power stealing circuitry for each stage of the environmental control system. In other words, the controller may include a first circuit and a second circuit for each stage of a multi-stage environmental control system.

Abstract: A power stealing system having an electrical load, a capacitive element having an input connected to the electrical load. Some power from the electrical load may go through the capacitive element to an input of a rectifier. A voltage regulator may have an input connected to an output of the rectifier to set and control a voltage level of the electrical power from the rectifier, and provide an output of power stolen from the electrical load. An amount of power flowing through the capacitive element may be less than one percent of power flowing through the electrical load.

Abstract: A circuit to isolate a first circuit node from second circuit node at certain times yet connect the first circuit node and second circuit node at other times. For example, the isolation circuit may isolate a reference node from a system ground during certain phases of operation, but temporarily connect the reference node to the system ground during other phases. An isolation circuit of this disclosure may include a pair of MOSFETs in a back-to-back connection. The MOSFETs may be placed between the two nodes to be isolated. The MOSFETS may be driven by a bipolar junction transistor (BJT). A control signal applied to the BJT emitter controls the operation of the pair of MOSFETs. The isolation or connection from the power supply reference node to system ground may be controlled by applying a HIGH or LOW logic signal to the PNP transistor emitter.
