Abstract

A computerized method for diagnosing a damper condition in a flow control unit includes providing a control signal to a damper. The control signal instructs the damper to move into a target position or to achieve a target flow rate through the flow control unit. The method further includes receiving pressure information including one or more pressure measurements from a differential pressure sensor of the flow control unit and using the pressure information and the control signal to conduct a damper performance diagnostic. The damper performance diagnostic includes at least one of: a stuck damper diagnostic, a predictive damper failure diagnostic, an improperly-sized damper diagnostic, and a damper leakage diagnostic.
