Retrofit kits

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
• Min-max setpoint value switching with switch contact provided by others
• Variable setpoint value adjustment with signal voltage 0 – 10 V DC or 2 – 10 V DC
• Push button to trigger a test run (only variants E01, E02, E03)
• Optional auxiliary switch, e.g. for end position sensing (only variant B52, B62, B72)
