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, also in continuous operation.
Components contained in the housing (Note: the housing cover can’t be removed):
controller electronics,
differential pressure sensor,
synchronous motor for the damper actuator.

Gear train disengagement
Manual control of the air dampers is possible by gear train disengagement (8) when the VAV Compact Controller is disconnected from the power supply.
