The throttle shutter can be coupled to the ventilation level control if necessary (

Information
The control output
“
Shutter
”
(0 - 10 V) is inverted at the factory, i.e. 10 V
…
0 V (10 V = shutter closed,
0 V = shutter completely open). This setting causes the shutter to open in the case of a line break to
the servo motor or failure of the control output (controller side) and avoids impairing the ventilation.
