To prevent the control from becoming unstable, a dead band is allowed within which the damper blade does not move
Volume flow parameters can be easily changed by the customer

Operating modes

Operating mode variable volume flow rate, q_vmin: minimum volume flow rate, q_vmax: maximum volume flow rate
Operating mode Constant value, q_vmin: Constant volume flow rate, q_vmax: 100 %

Commissioning

Principle of operation – LVC, TVR, TZ-Silenzio, TA-Silenzio, TVZ, TVA, TVJ, TVT

① Effective pressure transducer

② Actuator

③ Volume flow controller

④ Setpoint value signal

Air terminal units control the volume flow in a closed loop, which means: measurement – comparison – adjustment.
The volume flow rate is obtained by measuring a differential pressure. This is done with a differential pressure sensor. The integrated differential pressure transducer converts the differential pressure into a voltage signal. The actual volume flow rate is available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal flow rate (q_vNom).
The volume flow setpoint is specified by a higher-level controller (e.g. room temperature controller, air quality controller, building management system) or by switching contacts. Variable volume flow control can be set between_vmin and q_vmax. It is possible to override the room temperature control by forced switching, e.g. for a shut-off
The controller compares the volume flow setpoint with the current actual value and adjusts the internal actuator according to the control deviation.
Volume flow parameter q_vmin and q_vmaxcan be set on potentiometers.
