2.6 Electric and control cables
The ventilation unit has a power cable with earthed plug.
The plug serves as the ventilation nit’s main switch and
should be connected to an easily accessible wall socket.
There is a modular cable on top of the ventilation unit to
control the unit. The maximum length of the modular
cable is 40 meters. If you route the modular cable within a
building element, the cable must be routed in a
∅
20 mm
conduit, bearing in mind any subsequent cable replacement.
Ensure during the installation of the ventilation unit that
it is easy to access the cable connectors, among others,
for servicing and setting up.
Accessories are either connected to the ventilation unit’s
four-way connector (2 extra functions) or the external
connection modules (3 extra functions). The cables are
routed through the cable entries that are on top of
the ventilation unit. The connection of accessories is
described in the section “Units external connections”.
Connection cables for connection modules and accesso-
ries are not included in the supply.
2.7 Installation of the Smart control panel
A maximum of two Smart control panels can be con-
nected to the ventilation unit. These should be con-
figured with different ID numbers
(Settings/Display/
Display ID)
. A Smart control panel can be mounted up
to 40 meters from the unit (using 2 x 20 meter long
modular cables).
The front panel on the Smart control panel is released
using a screwdriver to push the retaining clips through
the holes on either side.
If several control panels are connected in chain, the
middle panel’s bus termination is moved to the “Open”
position. The jumpers do not need to be adjusted if only
one control panel is used.
Bus termination: Open
Bus termination: Terminated
The modular cable can be connected to any outlet
socket on the panel.
Finally, refit the front panel.
