Abstract
A system includes a modulating furnace and control circuitry. The control circuitry is configured to receive a call for heating associated with a quick heat cycle. In response to the call for heating, the control circuitry is also configured to operate the modulating furnace in a quick heat operating mode for a threshold time period. Subsequent to the threshold time period, the control circuitry is also configured to operate the modulating furnace in a modulating heat operating mode.
Claims20
A controller of a modulating furnace of a heating, ventilation, and air conditioning (HVAC) system, the controller comprising a tangible, non-transitory, computer-readable medium having computer-executable instructions stored thereon that, when executed, are configured to cause processing circuitry to:
- receive a call for heating;
- in response to a number of heating cycles executed by the modulating furnace between the call for heating and a previous call for heating meeting or exceeding a threshold number of heating cycles, associate the call for heating with a quick heat cycle;
- operate the modulating furnace in a quick heat operating mode for a threshold time period in response to the call for heating being associated with the quick heat cycle;
- and
- subsequent to expiration of the threshold time period, operate the modulating furnace in a modulating heat operating mode based on comparison of a set point temperature of a conditioned space and feedback indicative of a temperature of the conditioned space.
A heating, ventilation, and air conditioning (HVAC) system, comprising:
- a modulating furnace;
- and
- control circuitry configured to:
- receive a call for heating;
- associate the call for heating with a quick heat cycle based on a number of previous heating cycles executed since a previous call for heating associated with the quick heat cycle meeting or exceeding a threshold number of cycles;
- operate the modulating furnace in a quick heat operating mode for a threshold time period in response to the call for heating being associated with the quick heat cycle;
- and
- subsequent to the threshold time period, operate the modulating furnace in a modulating heat operating mode based on comparison of a set point temperature of a conditioned space and feedback indicative of a temperature of the conditioned space.
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.
