Functionality
The control panel has touch-sensi-
tive buttons, which means the re-
spective 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 con-
trol panel. The button assignments
and the LED signalling in both con-
trol panels are identical in terms of
functions.
Installation
Before reaching into the
ventilation unit, disconnect
all poles of the mains supply line
from the power supply.
If an RF module is not present, the
electrical connection must be car-
ried out with the ventilation unit dis-
assembled. Observe the installa-
tion instructions in the relevant us-
er manuals.
To provide protection against elec-
trostatic effects, an ESD armband
is to be applied.
Electrical connection
Ventilation unit side:
The socket of the connection ca-
ble's micro connection must be in-
serted into the plug of the BUS X7
micro connection on the ventilation
unit's control board.
If an RF module is present, the
socket of the connection cable's
micro connection must be inserted
into one of the dual micro connec-
tions on the RF module board.
The 2-part plug-in connector with
spring-type and screw-type ter-
minals is the connecting link be-
tween the connection cable and the
on-site cable for the external con-
trol unit.
The wires of the cable for the exter-
nal control unit are to be connected
to the part of the plug connection
with the screw-type terminals on
the ventilation unit.
Ensure that the wire assignment
matches the spring-type terminals
of the plug-in connector and the
spring-type terminals of the control
unit's connection board.
