Abstract: There is described a zone controller and method for identifying a root cause failure at a zone. The zone controller determines whether a temperature measurement deviates from a temperature setpoint of the temperature sensor (316), and generates a first repair code, a second repair code, and/or a third repair code. The first repair code replaces a temperature sensor (316) in response to detecting that a reading of the temperature sensor (316) has failed. The second repair code releases an operator override on the reading of the temperature sensor (316) in response to detecting that the reading of the temperature sensor (316) has been overridden. The third repair code releases an operator override on a setpoint of the temperature sensor (316) in response to detecting that the setpoint of the temperature sensor (316) is outside the predetermined setpoint range. One or more of these repair codes are provided to a remote device.

Abstract: Capabilities of a chiller water plant (106) are modeled using operational data, equipment data, and system configuration data enabling changes to be made to the configuration data and report the resulting changes in performance of the model.
