Application of reasoning rules for fault diagnostics of control-related faults

Abstract:

A system controls and monitors a heating, ventilation, and air conditioning (HVAC) system. The system receives raw data from HVAC equipment, controller performance monitoring (CPM) indicators associated with the HVAC equipment, and a set of rules associated with the HVAC equipment. The system processes the CPM indicators and the raw data using the set of rules to generate fault relevancies, and processes the fault relevancies.
