A heating, ventilation, and/or air conditioning (HVAC) system includes auxiliary control circuitry configured to communicatively couple to a thermostat of the HVAC system. The auxiliary control circuitry is configured to receive a control signal from the thermostat and block subsequent transmission of the control signal in response to receipt of data indicative of a detected refrigerant external to a refrigerant circuit of the HVAC system.

Refrigerant detection system with auxiliary control circuitry

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.

HVAC connectivity control systems and methods

A heating, ventilation, and/or air conditioning (HVAC) system includes secondary control circuitry configured to communicatively couple to primary control circuitry of the HVAC system that is configured to operate the HVAC system in a variable operating mode. The secondary control circuitry is configured to cause operation of the HVAC system in a calibration mode to determine a calibrated target temperature and transmit the calibrated target temperature to the primary control circuitry to enable operation of the HVAC system in the variable operating mode via the primary control circuitry based on the calibrated target temperature.
