Abstract: A control system for a heating, ventilation, and/or air conditioning (HVAC) system includes a controller. The controller is configured to control the HVAC system to condition an air flow based on first feedback from a first sensor of the HVAC system, receive second feedback from a second sensor of the HVAC system, and control the HVAC system to condition the air flow based on the second feedback instead of the first feedback when the first feedback from the first sensor being no longer available. The first feedback is indicative of a first operating parameter of the HVAC system, and the second feedback is indicative of a second operating parameter of a refrigerant flowing through the HVAC system.

Abstract: The present disclosure includes techniques that enable a conditioned air system to automatically restore functionality and/or to operate at reduced functionality when a fault is detected, for example, to facilitate reducing likelihood that continuing operation with the fault present will decrease lifespan of the conditioned air system. To facilitate improving operation of the conditioned air system when a fault is present, the control system of the conditioned air system may utilize substitute sensor data and/or adjust its control algorithm. In this manner, the control system may facilitate improving operational reliability and/or availability of the conditioned air system, for example, by adaptively adjusting its operation to enable the conditioned air system to continue operating even when a fault is present, while reducing likelihood that the continued operation will reduce lifespan of the conditioned air system.
