Abstract

A system for detecting cycling between heating and cooling settings in a Heating, Ventilation, and Air Condition (HVAC) system is disclosed. The system is configured to detect a fault in an HVAC system employing a sequencing controls strategy. The system calculates the number of transitions from the heating setting to the cooling setting and vice versa within a set time period, in order to generate an index of the system's performance. The system is configured to combine the generated performance index with other performance indices for air handling units or variable air volume boxes for detecting a fault.
