Abstract: In an aspect, an HVAC system includes an inducer motor to provide combustion airflow, and a pressure sensor to measure an output airflow pressure of the inducer motor. The HVAC system may initiate the inducer motor, and receive a pulse width modulation (PWM) signal from the inducer motor, wherein the PWM signal indicates a PWM signal of the inducer motor corresponding to a predetermined airflow pressure of the inducer motor and measured by the pressure sensor. The HVAC system may compare the PWM signal to a baseline value, and control the inducer motor based on the comparing of the PWM signal to the baseline value. The HVAC system may also generate a status notification of the combustion airflow of the HVAC system in response to the comparing the PWM signal to the baseline value.

Abstract: A system faults to a return air sensor integrated within a heating, ventilation, and air conditioning (HVAC) unit. The system transmits a signal to a remote sensor. The system determines that a return signal is not received from the remote sensor. The system obtains a temperature reading from the return air sensor. The system determines whether the temperature reading satisfies a temperature setting stored in the memory. In response to determining that the temperature reading does not satisfy the temperature setting, the system enables heating or cooling of the HVAC unit until the temperature setting is satisfied. In response to determining that the temperature reading satisfies the temperature setting, the system disables heating or cooling of the HVAC unit.

Abstract: The present disclosure relates to a gas valve assembly for a furnace. The gas valve assembly includes a gas valve including an inlet flange having an outer geometric profile and defining a gas inlet of the gas valve. The gas valve assembly also includes a bracket having a mounting panel, a first support flange, and a second support flange, where the mounting panel extends between and is integral with the first support flange and the second support flange. A slot is formed in the first support flange and defined by a portion of a perimeter of the bracket. The outer geometric profile of the inlet flange corresponds to a profile of the slot, and the slot is configured to receive and abut a portion of the outer geometric profile. A passage is formed in the second support flange and configured to receive a gas flow from the gas valve.

Abstract: A furnace system includes a burner assembly configured to generate combustion products within a primary combustion zone comprising one or more burners. The furnace system includes a panel disposed downstream of the burner assembly along a flow path for the combustion products, where the panel includes at least one panel opening. The furnace system also includes a secondary combustion air gap defined by one or more spacers disposed between the burner assembly and the panel, such that a secondary combustion zone is established between the burner assembly and the panel and/or downstream of the panel. The secondary combustion air gap is downstream from and external the burner assembly.
