12MOUNTING SWITCHES
CONNECTION TO A WIRED 3 POSITION SWITCH OR
A 3GANG SWITCH MODULE
To connect a wired 3-position switch, the
ventilation unit must be opened in a correct manner in order to reach the PCB.
This method can be found in the chapter
of the electric pre-heating element. The correct cable must then be led to the
PCB via the cut-out with grommet provided for this purpose in the ventilation
unit.
Finally, connect the cable to terminal X9 "Connection 3 position switch"
according to the following diagram.

L1 and L2 closed = medium (position
2) L1 open = low (position 1)
L1 is connected to terminal C
L2 is
connected to terminal 1 L3 is
connected to terminal 2
