5. Product information
16
If the room humidity increases by 7 %, the fan
engages automatically at performance level 1
(78 m³/h).
●
If the room humidity increases even
further, the unit switches to performance
level 2 (92 m³/h).
●
If there are no further increases, the unit
continues to run at performance level 1
until the humidity again falls below the
saved reference value.
If the humidity falls below the reference value,
overrun mode starts with the set overrun
time. The current reference value is then
saved. If the humidity does not fall below the
reference value within 60 minutes, the unit
switches to the set overrun mode and then
switches off.
H and KH
units can also be operated using
the light switch. The set operating program
starts when the light is switched on (
chapter 9.3). The operating program takes
priority over the automatic humidity process.
If the light is switched off, the unit continues
to run until the remaining overrun time has
passed. The automatic humidity process is
then assigned maximum priority again and
controls the unit as described above.
6. Environmental conditions and
operating limits
●
Maximum permitted temperature of the air
40 °C.
●
Resistance to interference according to
EN 55014-2 depending on pulse shape
and energy component 1000 to 4000 V.
If operating with fluorescent tubes, extra
interference suppression measures are
needed (L or C components or RC
modules, protection diodes, varistors)
because these values may 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).
