Ventilator groups
A ventilator group consists of a ventilator switch line and a drive line to open and close
the windows. As an option, a timer switch can be connected to the ventilator switch
line.
Every drive in a ventilator group reacts simultaneously to the signal from any ventila-
tor switch or timer switch for this ventilator group.
One ventilator group is integrated on the main circuit board. For additional ventilator
groups, optional daughter cards are added.

If you change the running direction of the drives, you must also re-label all the
RWA switches.

Replace the word "

" (close) with the word "
Auf
" (open) on every RWA switch.
Additional ventilator groups cannot be retrofitted; the number of additional ventilator
groups must be specified in the order.
