Abstract

A heating, ventilation, and air conditioning (HVAC) system includes a controller associated with a residence. The controller is configured to determine an expected value range for an operating parameter of a component of the HVAC system. Additionally, the controller is configured to receive a signal from a sensor indicative of a current value of the operating parameter of the component and determine if the current value of the operating parameter is outside the expected value range. Based on the determination that the current value is outside the expected value range, the controller is additionally configured to initiate a diagnostic mode of the controller. In the diagnostic mode, the controller is configured to collect diagnostic data associated with the HVAC system.
