  • Electronic volume flow controllers of Type Universal (dynamic) are designed for use with VAV terminal units.
  • Dynamic differential pressure transducer and electronic controller are fitted together in one casing
  • Actuator or spring return actuator is separate
  • The output signals of the room temperature controller, central BMS, air quality controller or similar units control the volume flow rate setpoint
  • Override control by means of switches or relays
  • Volume flow rate actual value is available as linear voltage signal
  • Controller parameters are factory set
  • On-site adjusting is not required

Standard filtration in comfort air conditioning systems allows for use of the controller in the supply air without additional dust protection. Since a partial volume flow is passed through the transducer in order to measure the volume flow rate, please note:

  • With heavy dust levels in the room, suitable extract air filters must be provided.
  • If the air is polluted with fluff or sticky particles or contains aggressive media, Universal (dynamic) controllers cannot be used


Parts and characteristics

  • Sensor for dynamic differential pressure measurements
  • Separate actuator
  • Mechanical stops for limiting the damper blade positions
  • Actuators with overload protection
  • Release button to allow for manual operation
