Abstract:
A control system for a heating, ventilation, and/or air conditioning (HVAC) system includes control circuitry having a storage device and a microcontroller. The storage device is configured to store faults. The microcontroller is configured to monitor for a condition of the HVAC system associated with a fault, store a fault in the storage device when the condition is detected, identify whether a duration of time that the fault has been stored in the storage device exceeds a threshold time period, and clear the fault from the storage device when the duration exceeds the threshold time period.
