Design and device parts
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 must not be
removed):
∂ Controller electronics,
∂ differential pressure sensor,
∂ synchronous motor for the damper actuator.

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