2.10.2 3-position switch with malfunction
indicator
The 3-position switches that are fitted with a malfunc-
tion indicator show when a malfunction or filter dirty
alert has occurred. Depending on the type of the 3-po-
sition switch, this is done in one of the following two
ways:
■
3-position switch with malfunction indicator.
In the event of a malfunction or filter dirty alert
the indicator lights up;
■
Wireless 3-position switch with malfunction indi-
cator.
The malfunction indicators will light up once this
3-position switch is used. One indicator will light
up green to indicate communication has been
established. Subsequently, in the event of a
malfunctionor filter dirty alert both indicators will
flash red 3 times. After that, both indicators will
light up green once more.
