Schematic illustration TA-Silenzio TA-Silenzio-Function

1 Integrated attenuator
2 Measuring probe
3 Control components, e.g. Easy controller
4 Damper blade with seal

The VAV terminal unit is fitted with a differential pressure sensor for measuring the volume flow rate.
The control components (attachments) include a differential pressure transducer that transforms the differential pressure into an electric signal, a controller, and an actuator; the control functions can be achieved with an Easy controller, with a Compact controller, or with individual components (Universal).
For most applications, the setpoint comes from a room temperature controller.
The controller compares the actual value with the setpoint and alters the control signal of the actuator if there is a difference between the two values.
An integral attenuator reduces the noise that is created by the restriction of the airflow.An integral attenuator reduces the noise that is created by the restriction of the airflow.
