Installing the wireless operating switch (accessories)
The ventilation unit can be operated via max. 6 wire-
less operating switches.
When selecting an installation site for the wireless
receiver and wireless operating switches, note that the
range may be reduced due to the following factors:
There may be no wireless reception.
■
On their way between transmitter and receiver, wire-
less signals are
damped
, e.g. by air or walls.
■
Wireless signals are
reflected
by metallic objects,
e.g. reinforcements embedded in walls, metal foil on
thermal insulation, thermal glazing with metallised
thermal vapour deposit.
■
Wireless signals are
isolated
by service ducts and
lift shafts.
■
Wireless signals suffer
interference
from devices
that also operate with high frequency signals,
such as
–
Computers
–
Audio and video systems
–
WiFi
–
Electronic transformers
–
Pre-ballasts
Where to install wireless components
■
Choose the installation location such that the radio
signals impinge on walls and other equipment as
horizontally as possible.
■
Install at mid wall height,
at least 1 m
below the ceil-
ing
■
Distance to other transmitters (GSM, DECT, WLAN)
at least 2 m
■
Distance from room corners
at least 0.2 m
■
Do not install in wall recesses.
