ON / OFF key:
After actuating the ON / OFF key whilst switched
off, the unit starts as soon as the humidity in the
room (RH) is 4% higher than the target value set
for the humidity in the room. The start sequence is:
Fan motor ON → solenoid valve ON 10 seconds
and then OFF → compressor ON. If the room
humidity is lower than the target value set for the
humidity in the room, then the "COMP. ON" indi-
cator flashes and the unit is in standby mode (not
operating).
If the ON / OFF key is actuated during operation,
the unit and the COMP ON" display switch off. The
ON / OFF delay time of the compressor is 1
minute.

SET HUMIDITY - Desired humidity setting:
After the unit is switched on, the target room
humidity can be adjusted up or down by pressing
the arrow keys. As soon as the room humidity rea-
ches the target humidity set, the compressor and
the fan motor stop. The target room humidity set is
displayed for 3 seconds during the adjustment and
then reverts to the current measured room
humidity.
NOTE:

If the unit is restarted it reverts to the pre-
vious setting

The adjustment steps for the target humidity
are 5% ( RH) per key press. The adjustment
range for the target humidity should lie
between 30% and 70% ( RH)
If the humidity lies below the target humidity set
(i.e.:
r
RH <-3%), the compressor and the fan
motor stop. If the humidity is higher than the target
humidity set (i.e.:
r
RH >+4%), the unit restarts
with a 3 minute delay.
Example:
If the target humidity = 50% RH, but the
room humidity is 47% RH, then the compressor
and fan motor stop and the "COMP. ON" indicator
flashes (standby display!). While the room humidity
rises to 54% RH, the unit restarts with a 3 minute
delay time in accordance with the start function
sequence.
The target room humidity value must be set within
3 seconds by pressing the up arrow or down arrow
keys. Then the current room humidity is displayed
again.

Segment display for humidity, room temper-
ature and malfunction code:
The standard display is the current measured room
humidity. The humidity value to be changed is dis-
played for 3 seconds by pressing one of the arrow
keys [2] to set the target room humidity. If the
ROOM TEMP key is pressed, the current meas-
ured room temperature is shown in the display for
5 seconds and then the display automatically
switches back to the current measured room
humidity.
