The VAV air flow controller is equipped with an effective pressure sensor to measure the air flow. Control components (optional accessories) include an effective pressure sensor that converts the effective pressure into an electrical signal, a controller and an actuator; The control functions can be implemented with the Easy controller, Compact controller or individual components (Universal or LABCONTROL). In most cases, the temperature value is set by the room temperature controller. The flow controller compares the actual and set values and, if there is a deviation, generates a corresponding signal to the valve actuator.
