    Abstract: A control system of a heating, ventilation, and/or air conditioning (HVAC) system includes a primary memory configured to store core control logic defining a plurality of control outputs transmissible by the control system during operation of the HVAC system, a secondary memory configured to store operating data defining a plurality of operating parameters associated with the HVAC system, and processing circuitry communicatively coupled to the primary memory and the secondary memory. The processing circuitry is configured to cause the processing circuitry to operate the HVAC system using the core control logic stored in the primary memory and the operating data stored in the secondary memory.

    Abstract: A refrigerant leak detection system includes a sensor configured to detect a leaked portion of refrigerant external to a closed-loop refrigeration circuit of a heating, ventilation, and/or air conditioning (HVAC) system, memory circuitry having instructions stored thereon, and processing circuitry configured to execute the instructions to perform various functions. The functions include receiving, from the sensor, sensor feedback indicative of the leaked portion of the refrigerant. The functions also include transmitting, based on the sensor feedback, a notification indicative of the leaked portion of the refrigerant to a third party security server.

    Abstract: A system includes two stage HVAC equipment and processing circuitry configured to receive a call for conditioning and, in response to the call for conditioning, execute a recovery mode algorithm. The recovery mode algorithm is configured to determine an elapsed time between the call for conditioning and an ending of a recent cycle and compare the elapsed time to a threshold time period. The recovery mode algorithm is also configured to, in response to the elapsed time being below the threshold time period, determine a first stage up time based on a first function corresponding to the elapsed time being below the threshold time period. The recovery mode algorithm is also configured to, in response to the elapsed time meeting or exceeding the threshold time period, determine a second stage up time based on a second function corresponding to the elapsed time meeting or exceeding the threshold time period.

    Abstract: A system includes a two stage heat exchanger and a processor. The processor is configured to receive a call from a thermostat and execute, in response to the call, an adaptive staging algorithm. The adaptive staging algorithm is configured to determine, in response to a recent cycle of the two stage heat exchanger being a first stage cycle, a first stage up time of the two stage heat exchanger as a first function of a first value, the first value corresponding to the recent cycle being the first stage cycle. The adaptive staging algorithm is also configured to determine, in response to the recent cycle of the two stage heat exchanger being a second stage cycle, a second stage up time of the two stage heat exchanger as a second function of a second value, the second value corresponding to the recent cycle being the second stage cycle, where the first and second values are different.
