Additional switching output
Work must only be carried out on the additional
switching output by a qualified electrician in
accordance with the country-specific requirements and
standards.
The appliance has an additional switching output X16
(potential-free contact) that can be used to connect
other appliances, such as a ventilation system that is
available at the installation site. The contact is closed
when the fan is switched on, and is opened when the
fan is switched off.
The switching output is located under a cover. Maximum
switching power 30 V/1 A (AC/DC). The signal that is
connected to the contact must correspond to class of
protection 3.
Networked operation
Several appliances can be networked together. The
light and fan on each of the appliances are operated
synchronously.
Connect the appliances in series via the connector
sockets X1 and X2 (equal value). The sequence of the
networking does not have any effect. If the enclosed
network cables are too short, use a commercially
available network cable (min. Cat. 5, shielded).
Maximum number of networked appliances: 20. Total
length of all of the network cables: 40 m. During the
initial installation, a qualified electrician must check
that the system functions correctly.
If one of the networked appliances fails (power
interruption, network cable disconnected), this leads to
the fan function being blocked for the entire system. All
of the buttons on the appliance flash.
When changing the configuration, the system must be
re-initialized:
1 Unscrew the cover plate.
2 Press and hold the reset button until both LEDs
light up continuously (approx. 5 seconds). Then
release the button within 5 seconds.
3 Screw on the cover plate.
4 After initialization, have a qualified electrician
check that the system functions correctly.
