WARNING
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 blower is switched on, and is opened when the
blower 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.
Connection for window contact switch
AA 400 510
Work on the connection for the window contact switch
must only be carried out by a qualified electrician in
accordance with the requirements and standards of the
country in which in the appliance is being used.
The appliance has a connection (X17) for a window
contact switch. The window contact switch can be flush
mounted or surface mounted. You will receive the
window contact switch AA 400 510 separately as an
accessory. Please observe the installation instructions
enclosed with the window contact switch.
If a window contact switch is connected, the extractor
hood's ventilation system will only work with the window
open. The lighting will work even if the window is
closed.
If you switch on the ventilation system with the window
closed, the button for the ventilation setting you have
selected will flash, and the ventilation system will not
switch on.
If you close the window while the ventilation system is
on, the appliance will switch the ventilation system off
within 5 seconds. The button for the ventilation setting
you have selected will flash.
The entire ventilation network and window contact
switch must be assessed by a master chimney sweep.

Networked operation

Several appliances can be networked together. The light
and blower on each of the appliances are operated
synchronously.
18
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: 131 feet (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 blower 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.
