10 Maintenance

Variant 1: Fan switches on automatically when
the relative room humidity in the area of the fan
exceeds the preset switching point. Switching off
takes place after the humidity has fallen below the
switching point and the set overrun time has
elapsed. With additional switch S1, the fan can be
taken out of operation.
Variant 2: Fan switches on automatically via hu-
midity control (as in variant 1)
or
manually via
light switch. With a relative room humidity over
the switching point, the fan can no longer be
switched off, not even with the light switch. The
fan switches off when the room humidity in the
area of the fan is under the switching point and
the overrun time has elapsed.
10 Maintenance
The unit is maintenance-free.
11 Cleaning
Clean fan regularly, especially after it has
not been used for a long time.
NOTICE Risk of damage to unit if incorrect
cleaning agent is used.

Overrun time (max. 25
min.).
Wait for overrun
time and reduce if neces-
sary.
Motor’s thermal over-

the motor has cooled
down. Cool-down time
can be up to 10 minutes.

automatically after cool-
ing down.
Fan does not switch
off or fan switches on
when not wanted.
A high-impedance
voltage is present at
terminal L1 due to a
glow lamp in the con-
trol switch, cables laid
in parallel (induction)
or transformers or
other electrical com-
ponents.
Recommenda-
tion: Wire X2 capacitor
(220 nF/ 250 V) to zero.
