Abstract: An energy efficient heating, ventilation, and air conditioning (HVAC) system includes a variable capacity compressor configured to operate at a plurality to operating capacities and a control system communicatively coupled to the variable capacity compressor. The control system is configured to receive data indicative of a temperature within a conditioned space, receive data indicative of a set point temperature of the conditioned space, initialize operation of the variable capacity compressor, and ramp up operation of the variable capacity compressor to an intermediate operating capacity of the plurality of operating capacities during initial operation of the variable capacity compressor, where the intermediate operating capacity is less than a full operating capacity of the plurality of operating capacities.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a conditioning system configured to condition a return air flow directed through the HVAC system and a control system configured to determine a difference value between an operating parameter value of the return air flow and a sensed operating parameter value of a space serviced by the HVAC system, retrieve a stored target operating parameter value of the space, and operate the HVAC system based on the difference value, the stored target operating parameter value, or both.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes a heat exchanger configured to receive a working fluid and place the working fluid in a heat exchange relationship with an air flow directed across the heat exchanger, a switch configured to detect an operating parameter of the HVAC system, where the switch is configured to interrupt operation of the HVAC system in response to detection of a first value of the operating parameter greater than an operating parameter limit value, and a sensor configured to detect the operating parameter of the HVAC system. The HVAC system also includes a controller communicatively coupled to the sensor, where the controller is configured to receive data indicative of a second value of the operating parameter, compare the second value of the operating parameter to a threshold value of the operating parameter, wherein the threshold value is less than the operating parameter limit value, and adjust operation of the HVAC system in response to a determination that the second value of the operating parameter is greater than the threshold value.

Abstract: A control system of a heating, ventilation, and/or air conditioning (HVAC) system includes a data communication controller configured to receive, via a first wireless communication protocol, data from a sensor indicative of an operational parameter of the HVAC system. The data communication controller is also configured to receive, via an electronic device communicatively coupled to the data communication controller, a control instruction, and to transmit, via a second wireless communication protocol different from the first wireless communication protocol, a control signal to adjust operation of an HVAC component configured to enable supply of conditioned air to a structure serviced by the HVAC system based on the data and the control instruction.

Abstract: A furnace system of a heating, ventilation, and/or air conditioning (HVAC) system includes a burner assembly having a burner enclosure configured to receive a fuel for ignition to generate heated combustion byproducts. The furnace system also includes a controller configured to detect a value associated with a wave signal transmitted through the burner enclosure and operate the furnace system based on a comparison between the value and a threshold value.
