Installation

The letters in this chapter refer to the
illustrations at
document.
1. If wall-mounted model:
Fasten the housing for wall mounting
in the living area at a user-accessible
location on the wall:
■ At least 1 metre above the floor;
■ At most 1.5 metres above the floor.
2. Fasten wall frame A with screws F (not
included) to the wall, the housing for
wall mounting or the installation plate.
3. Route the cables through the desired
design frame X and adjust the size of
window D.
4. Connect the cables to the control unit
and ventilation system.
■ Consult the relevant manual for
details of connection to the ventilation
unit.
5. Fasten the unit with design frame X and
format adaptation window D to frame A
with screws E.
Use the following screws during
replacement:
■ Hardened and galvanised screw
2.2x12 PT10;
■ M2.2*12 cross-head Plas-Fix 45°.
6. Push cap C into place.

4.1 Points of attention – RF
model
this
An RF signal can be disrupted by various
sources, both large metal objects and other
RF signals.
Select a location to fit the control unit so
that there are no large metal objects in the
vicinity of the ventilation unit and the control
unit. If the RF range is not far enough, an RF
Repeater may be used.
4.2 Points of attention – 0-10V
model
Beware of electromagnetic interference
(EMC) during installation.
■ Ensure that there is a barrier (e.g. a
separate channel or compartment) or
at least 150 mm between the power
cables (e.g. 230V) and the interference-
sensitive cables (control, low voltage,
interface, LAN, digital or analogue
signal);
■ If interfering power cables and
interference-sensitive cables have
to cross, ensure that this is done
perpendicularly.
This minimises the chance of EMC and
provides the best communication.
