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.
