Abstract: Systems and methods involve controlling a variable-speed blower in a heating, ventilating, and air conditioning (HVAC) system to ensure the setting of a blower-proving switch to confirm airflow in a building. In one instance, a method involves ramping up the variable-speed blower so that the associated static pressure reaches a making point pressure of the blower-proving switch and then reducing the power to a desired power level. The method may also include maintaining the power level above a breaking point pressure. Other systems and methods are presented.

Abstract: 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.

Abstract: Provided are a method and apparatus for reducing a refrigerant pressure difference within are HVAC system having a controller, one or more compressors, and at least two paths of refrigerant piping comprising alternative paths for refrigerant flow through the HVAC system. A valve is coupled to each refrigerant piping path for permitting, or preventing, refrigerant flow through each of the alternate paths of refrigerant piping. The controller may open at least one valve for a defined period of time in response to a triggering input to allow a refrigerant pressure difference within the HVAC system to dissipate across the opened valve.
