An HVAC system includes a central controller which communicates with a multiple of HVAC components over a digital communication bus. The central controller maintains an ordered fault list that includes the source of a fault, a description of the fault, the last occurrence of the fault, and the number of sequential occurrences, or repetitions across the entire HVAC system.
