1. A heating, ventilation, and air conditioning (HVAC) system, comprising:
a controller configured to:
determine, via a processor of the controller, an expected value range for an operating parameter of a component of the HVAC system;
receive, via a communication component of the controller, a signal from a sensor indicative of a current value of the operating parameter of the component at a first frequency;
determine, via the processor, that 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, automatically initiate, via the processor, a first diagnostic mode of the controller, wherein in the first diagnostic mode, the controller is configured to collect diagnostic data associated with the HVAC system at a second frequency;
determine, via the processor, an additional expected value range for an additional operating parameter of an additional component of the HVAC system;
receive, via the communication component, an additional signal from an additional sensor indicative of an additional current value of the additional operating parameter of the additional component;
determine, via the processor, that the additional current value of the additional operating parameter is outside the additional expected value range; and
based on the determination that the additional current value is outside the additional expected value range, automatically initiate, via the processor, a second diagnostic mode of the controller, wherein the controller is configured to collect additional diagnostic data associated with the HVAC system at a third frequency, and wherein the second diagnostic mode differs from the first diagnostic mode at least in that the third frequency is greater than the second frequency.
