J 7
Jumper 7 open: Ventilation level 3 is
reset after an hour.
J 8
RB-ZF4 or RB-D1-ZF4 room air
control active: Leave factory setting,
J8 must be bridged.
J 9
Jumper 9 open: The ventilation unit
can be switched off at the room air
control. Jumper 9 bridged:
RB-ZF4: Switch-off function blocked
RB-D1-ZF4: Ventilation unit runs in
"Humidity protection ventilation" ven-
tilation level in OFF switch position.
