Abstract: Example embodiments of the present disclosure relate to a control system for controlling an HVAC device where the control system includes a temperature sensor that provides a signal indicative of a temperature associated with the HVAC device, an orientation sensor that provides a signal indicative of an operating orientation of the HVAC device, and control circuitry that receives the temperature signal and the orientation signal from the orientation sensor. The control circuitry selects an operating thermal control set point from a plurality of stored thermal control set points based at least in part on an orientation signal, determines a temperature sensor input based on the temperature signal and compares the temperature sensor input to the operating thermal control set point, and operates the HVAC device based at least in part on that comparison.

Abstract: Methods and related systems for operating a furnace are disclosed. In an embodiment, the method includes activating a burner assembly and a first fan of the furnace to combust fuel and air and circulate combustion gases along a flow path extending through a heat exchanger of the furnace. In addition, the method includes operating a second fan of the furnace to circulate air across an external surface of the heat exchanger of the furnace and produce a conditioned airflow. Further, the method includes monitoring one or more parameters of a motor of the second fan indicative of an airflow rate of the conditioned airflow, and deactivating the burner assembly, whereby combustion of the fuel and air in the furnace ceases, in response to the one or more parameters indicating that the airflow rate is less than a minimum airflow rate.
