  • Positive lock connection with CAV controller or flow adjustment damper

 


Optional accessories for type RN


  • Auxiliary switch with adjustable switching points, for example for capturing the end positions

Application


Parts kits for the retrofit of mechanical self-powered volume flow controllers or flow adjustment dampers with an actuator for the setpoint value adjustment of
CAV controllers.

Types RN, EN, VFC

  • Min/max switching of the volume flow rate setpoint values
  • Variable adjustment of the volume flow rate setpoint


Flow adjustment damper type VFR

  • Min/Max change of the damper blade position
  • Variable adjustment of the damper blade position


Parts and characteristics


Setpoint value adjustment, supply voltage and special functions of the drive variant and its adjustment range to the various basic devices (see variant description).

  • Adjustment of the setpoint values to mechanical stops
  • Adjustment of the setpoint values to potentiometers
  • Supply voltage 24 V AC/DC or 230 V AC
