2.2 Design and device parts
2.2.1 Design
The VAV compact controllers consist of a differential pressure sensor, actuator and
digitally configurable control electronics. They are intended for mounting on damper
shafts of a minimum length of 30 mm. They consist of base and 2-sectional housing.
Components contained in the base:
• Steel base plate with damper drive shaft fixing for different drive shaft
diameters / cross-sectional areas (cf. section 2.3) and angular rotation limiter,
• maintenance-free, low-noise gear train,
• magnetic hysteresis clutch with practically contact-free force transmission; this
means that the actuator is locking- and overload-proof.
Components contained in the housing (Note: Housing cover must not be removed):
• Controller electronics,
• differential pressure sensor, and
• synchronous motor for the damper actuator.
2.2.2 Main device parts
1 Shaft attachment screw
2 LED
3 Configuration and maintenance interface
(below cover)
4 Connection nozzle for measuring differential
pressure in the VAV box
5 Connection nozzle for measuring differential
pressure in the VAV box ("+": Side with higher
pressure)
6 6-core connecting cable (power and
communications)
7 Disengagement of gear train
8 Rotation angle display
9 Rotation angle check screw
Manual control of the air dampers is possible by gear train disengagement (7)
when the VAV compact controller is disconnected from the power supply.
