Functionality
The control panel has touch-
sensitive buttons, which means the
respective operating functions are
triggered by touching the relevant
buttons. The ventilation unit can be
operated at the same time with the
internal and the external control
panel. The button assignments
and the LED signalling in both
control panels are identical in
terms of functions.
Installation
The cable and an in-wall
switch box for the external
control panel must be installed in
advance on site. On the ventilation
unit side, the cable connection for
the external control panel must
be established in the course of
connecting the power supply.
Electrical connection
Ventilation unit side:
The wires of the connecting cable
are to be connected to the BUS X7
clamping point on the ventilation
unit control board according to
the colour coding.
The 4-pin plug-in connector is
the connecting link between the
connecting cable and the on-
site cable for the external control
panel.
The wires of the cable for the
external control panel are to be
connected to the plug-in connector
