points achieve their allocated set suction performance.
The suction level and the selected turbo level are automatically saved and reset when the multi
use mode is selected the next time.
5.4.3 Automatic Operation / Manual Operation

With the appliances, which are connected to the Quattro Control Box, it is possible to switch the suction
turbine on and open the relevant suction channel (when the electrical appliance is activated) or close the
relevant suction channel (when the electrical appliance is deactivated).
The switching threshold, the point in time when a suction channel is opened / closed, can be set individu-
ally for each suction channel (see section 5.6.4).
Manual operation:
