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.

Abstract: A computerized method for conducting a performance diagnostic for a damper in a flow control unit includes providing a control signal to the 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 includes measuring a first differential pressure using a pressure sensor of the flow control unit at a first time before providing the control signal to the damper and measuring a second differential pressure using the pressure sensor of the flow control unit at a second time after providing the control signal to the damper. The method includes calculating a rate of change between the measured differential pressures based on a difference between the first and second measured differential pressures and a difference between the first and second times. The method includes predicting failure of the damper in response to the calculated rate of change being less than a threshold rate of change and outputting a damper failure prediction to at least one of a user interface device, a local memory, and communications electronics.
