Field: Thermal processes and apparatus (Mechanical engineering)
Classification: CPC F  G | IPC F  G

Claim 15:
16. A heating, ventilation, and air conditioning (HVAC) system, comprising:
a modulating furnace; and
processing circuitry configured to receive a call for heating from a thermostat and, in response to the call for heating, execute a quick heat algorithm to:
determine a number of heating cycles between the call for heating and a previous call for heating associated with a quick heat cycle;
compare the number of heating cycles to a threshold number of cycles;
in response to the number of heating cycles meeting or exceeding the threshold number of cycles, operate the modulating furnace in a quick heat operating mode; and
in response to the number of heating cycles being below the threshold number of cycles, operate the modulating furnace in a modulating heat operating mode.
