    Schematic illustration of the TVR TVR-Function

    ① Effective pressure sensor
    ② Damper blade
    ③ Double lip seal
    ④ Control components, e.g. an Easy controller

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

    Nominal sizes

    100 – 400 mm

    Volume flow rate range

    Volume flow rate control range (unit for static effective pressure

    measurements)

    Approx. 15 to 100% of the nominal volume flow rate

    Minimum differential pressure

    Up to 117 Pa (without circular silencer)

    Maximum differential pressure
