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 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 electric drive.
