Danger!
Risk of fatal electric shock from touching live
connections. Pull the mains plug before starting
to work on the device.
• Remove the unit front cladding as described in
section 4.6.
• Now place the 2-core cable (minimum 0.35 mm 2 ) in
the respective cable routing to the PCB.
• Connect the lines to the connection "X 16" (alarm out-
put) in accordance with figure 4.14 "Wiring scheme".
4.12 Function check-out
Once all supply lines are correctly installed in accord-
ance with the wiring scheme, check the functions of the
remote control, the domestic ventilation unit and the
bypass (see section 5.1.3). When doing so, note that the
unit must not be started until all ventilation ducts are
connected to the unit and the unit and all ductwork are
completely sealed.
In the sections 4.4 to 4.8 of the operating manual you
will find in detail all the settings for the individual oper-
ating modes and the special functions. For testing func-
tions proceed as follows:
• Select the "night" operating mode and check that the
fans in the domestic ventilation unit are operating at
low output.
• Select the "day" operating mode and check that the
fans in the domestic ventilation unit are operating at
medium output (AIR2).
• Activate the special function "advance". Check that
the fans in the domestic ventilation unit are operating
at medium output (AIR2).
• If the output stages are not correctly switched, you
must check the wiring on the terminals of the remote
control and the domestic ventilation unit.
5 Start-Up
The start-up and the operation of the unit as well as in-
struction to the user must be done by a competent per-
son.
Please note that the device can only be started up if all
ventilation pipes of the device are connected and the
entire device is closed.
As part of the start-up it is necessary to adjust the do-
mestic ventilation unit.
The domestic ventilation units are delivered ex factory
with basic setting of both fans. As each fresh air and ex-
haust air installation is different and thus offers differ-
ent external resistance in the air ducting you will have
to separately adjust the fresh air and the exhaust air fan
to suit.
You can adjust the domestic ventilation unit using the
remote control. Below are the necessary steps.
5.1 Adjustment of the Digital Remote Control
To optimally match the system parameters to the re-
quired conditions it is necessary to set these parame-
ters with the remote control. The system parameters
are located in an upper operation level and should only
be set by an expert technician.
