Description
The VAV air flow controller is equipped with an effective pressure sensor to measure air flow.
Control components (optional accessories) include an effective pressure sensor, which converts the effective pressure into an electrical signal, a controller and an actuator; The control functions can be implemented using the Easy controller, Compact controller or individual components (Universal controller).
For most applications, the setpoint comes from the room temperature controller.
The controller compares the actual value with the setpoint and modifies the drive control signal if there is a difference between the two values.
A built-in silencer reduces noise caused by restricted airflow.
Standard sizes 125 – 315 mm
