Gaggenau AI442720 Installation Guide

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.

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:

Unscrew the cover plate.

Press and hold the reset button  until both LEDs 
light up continuously (approx. 5 seconds). Then  
release the button within 5 seconds.

Screw on the cover plate.

After initialization, have a qualified electrician 
check that the  system functions correctly.
