Technical information

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	34 – 7591 m³/h or 10 – 2108 l/s
Volume flow rate control range (unit for dynamic effective pressure measurements)	Approx. 10 – 100% of the nominal volume flow rate
Volume flow rate control range (unit for static effective pressure measurements)	Approx. 15 to 100% of the nominal volume flow rate
