1. Switch off all supply circuits.
2. Remove front cover(s) Installation
instructions for ventilation unit.
3. Lift electronic slide-in module and pull out
of the electronics compartment (depend-
ing on unit type, first remove the fixing
screws). Hang slide-in module in fitting
studs (if present) Installation instruc-
tions for ventilation unit.
4. Affix additional circuit board "ZP2" on con-
trol console "K" by pressing the 4 pre-fitted
spacers into the control console's holes
until they engage.
5. Connect ZP 2 to the main circuit board
with the RJ45 cable supplied Arrows,
previous diagram. If using several addi-
tional circuit boards, connect in series.
6. Set DIP switches
board ZP 2 depending on connection
variant (A, B or C) desired.
A Supply air with
pressure consistency:
Supply air fan is operated
with constant pressure
Exhaust air with
B
pressure consistency:
Exhaust air fan is operated
with constant pressure
C Filter monitoring by
measuring differential
pressure before and
after the outside air filter
of the ventilation unit

NOTICE
Danger of short-circuits/damage to unit
should water enter the electronics com-
partment.
● Ensure a correct, sealed pressure tubing
supply through the ventilation unit's cable
feedthrough.
● Only feed pressure tubing individually
through the cable feedthrough into the
ventilation unit.
● Correctly push through cable feedthrough,
check and ensure seal integrity.
● Feedthroughs not needed must remain
sealed.

1. Secure pressure connection socket in
supply air / exhaust air duct with mounting
material supplied by the customer taking
account of function (supply air/exhaust air
with pressure consistency).
2. Guide pressure tubing supplied into pres-
sure connection socket.
3. Use material supplied by customer to pre-
vent it from falling out (adhesive tape).
