摘要： An HVAC system, comprising a plurality of sensors, a tandem compressor comprising a first compressor and a second compressor, and a controller communicatively coupled to the plurality of sensors and the tandem compressor. The controller may determine a first interruption of power to the tandem compressor and identify a sensor corresponding to the first interruption of power. The controller is further operable to determine that the first interruption of power was caused at least in part by the refrigerant associated with the first compressor exceeding a tolerance condition. The controller may also reconfigure the tandem compressor, wherein on or off settings of the first compressor and the second compressor are determined based on a required load operation of the tandem compressor and the determination that the first interruption of power was caused at least in part by the refrigerant associated with the first compressor exceeding the tolerance condition.

摘要： An HVAC system includes a plurality of sensors, a tandem compressor, and a controller. The tandem compressor comprises a first and second compressor, each comprising a crankcase heater. The controller determines that one of the sensors has failed, and in response, initiates the first and second crankcase heaters and transmits an alert indicating that one of the sensors has failed. Further, the controller may disable threshold logic such that the first and second compressors are controlled independently of a determination whether the tandem compressor is operating outside of a threshold range. The controller operates the first and second compressors according to a safe mode, wherein first on or off settings of the compressors are determined based on a first required load operation of the tandem compressor. The first required load operation is determined from a first temperature demand of a structure associated with the HVAC system.

摘要： According to one embodiment, a system includes at least one of a cooling system and a heating system, an automation controller, a sensor, and a switch. The automation controller provides a first input indicating a first temperature set point. The sensor detects a temperature of a second space proximate the sensor and provides a second input indicating the temperature of the second space and a second temperature set point. The switch activates at least one of the cooling system and the heating system based on the second temperature set point in response to a determination that the second input overrides the first input.

摘要： In various implementations, compressor operation in an air conditioner may be managed by maintaining oil viscosity, a temperature differential, compressor sump temperature, and/or suction pressure. Properties of the air conditioner or portions thereof, such as the compressor, may be determined. To manage compressor operations, operation(s) of the air conditioner may be adjusted based on one or more of the determined properties.
