VAV VV550 Controller Programming and Operation
Pressure independent control - When a valid flow value is present, the controller operates under
pressure independent control. If after an airflow sensor failure, the airflow returns to the valid range
(airflow value greater than 10% of configured nominal airflow), the controller automatically
resumes pressure independent control.
Initiate Calibration button: The calibration sequence enables the controller to calibrate the air
valve position and the water valve position.
