    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: Examples of the present disclosure relate to climate control systems and air handler units with improved leak detection, along with method for installing these systems. In some examples, the climate control system comprises a heat exchanger configured to exchange thermal energy between a conditioned airflow and a refrigerant fluid; a drain pan arranged to collect condensate produced at the heat exchanger, the drain pan including one or more drains configured to route condensate out of the drain pan; a refrigerant leak sensor coupled to the drain pan and positioned above the one or more drains and configured to detect a refrigerant leak; and control circuitry operably coupled to the refrigerant leak sensor, the control circuitry configured to: receive a signal from the refrigerant leak sensor indicative of refrigerant located outside the closed circuit associated with the heat exchanger, and determine a refrigerant leak has occurred based on the signal.

    Abstract: Architectures or techniques are presented that can determine a setting for an environment control (EC) or HVAC system in response to a fault with the EC system that controls an environment of an occupant. Significantly, the determined setting can be intentionally selected as one that does not comport with the expectations or desired comfort level of the occupant. Thus, a condition can be created in the environment that is determined to be likely to cause the occupant to examine a user interface associated with the EC system. The user interface can present an indication of the fault, which otherwise may go unnoticed, particularly in cases where the occupant has no reason to interact with the EC system due to the environment meeting expectations.
