Version 2:
The fan is switched on
automatically, controlled by the humidity level
(as version 1) or manually by the light switch.
If the relative humidity level remains above
the switching point threshold, the fan cannot
be switched off, even with the light switch.
The fan switches off when the humidity level
drops below the switching point threshold and
once the defined overrun time has expired.
Valid for both versions:
1. Ambient humidity: approx. 50 … 90 %
relative humidity (factory setting
approx. 70% relative humidity)
2. Overrun time: approx. 0.5 … 18 min
(factory setting: approx. 12 min)

operational limits
●
Maximum permitted airstream
temperature: +40 °C.
●
Resistance to interference complies with
EN 55014-2, depending on the pulse shape
and energy factor 1000 to 4000 V. If
operating with
fluorescent tube lighting
,
additional interference suppression
measures (L, C components or RC
modules, protection diodes, varistors)
are needed, as these values can be
exceeded.
●
Recommendation: Connect a X2-capacitor
(220 nF/250 V) against neutral lead in
case of a switch with negative-glow lamp.
The capacitor is to be provided by the
customer.
●
Storage: Store unit exclusively in a dry
location (-20 to +50 °C).

Installation preparations
8.
Use mounting material suitable for base and
of sufficient dimensions. Ensure sufficient air
supply.
8.1 Wall
NOTICE
If the surface is uneven, there is a dan-
ger of short circuits and damage to the
device if water can penetrate the
housing.
Make sure there is a flat surface
in the area of the sealing ring [5]. If
necessary, provide additional sealing
measures.
The prescribed minimum distances
between the wall and the ceiling
shown in the figure must be observed.
1. Make sure the housing has a level base.
2. Fit wall breakthrough or drill core hole.
Minimum diameter, 105 mm.
Recommendation: Fit wall sleeve
WH 100. Fit wall breakthrough with a
minimum diameter of 115 mm.
Use mounting plate ZM 11 for
rectangular wall breakthroughs.
3. Lay power cable (recessed) up to place of
installation, see above for spacing.
