The desired value can be adjusted in increments of 5%
by pressing button B. When selecting the humidity output,
the desired value is blinking. The word DESIRED appears
on the display (E). The setting for the relative humidity
ranges from a minimum of 30% to a maximum of 70%.
CO means continuous use. A relative humidity of between
40 and 60% is recommended. After a few seconds, the
display automatically changes to show the current value
(CURRENT) (E). Upon reaching the desired relative humi-
dity, the unit automatically switches off (display shows
DESIRED and CURRENT) (E). If the desired relative humi-
dity falls, the appliance automatically switches on again.
Quick display of current relative humidity
When the unit is switched off (cable is connected, rotary
switch to position G (off)), the current relative humidity can
be shown in the display by briefly pressing one of the B
buttons. The display automatically disappears after a few
seconds.
C) Change Ionic Silver Stick
®
The symbol C in the display indicates that the Ionic Silver
Stick
®
(ISS) must be changed. The symbol remains visible
until both B buttons are pressed and held down for approx.
5 seconds.
D) Cleaning the appliance
The symbol D in the display indicates that the appliance
must be cleaned. Refer to section «Cleaning/maintenance»
to learn more about how to clean your humidifier. The sym-
bol remains visible until both B buttons are pressed and
held down for approx. 5 seconds.
E) Current/Desired Display
If DESIRED appears on the display, the value in % next to
it signifies the desired relative humidity, i.e. the desired
value is shown. If the display shows CURRENT, then the
current relative humidity is shown.
A) Switching on/off
Turn rotary switch A from the G (off) position to position H or
J as required. Position J is especially quiet (night mode). Po-
sition H (normal mode) achieves maximum humidity output.
The disc rotation speed remains constant with both mode
selections. The fan rotation speed increases with level II. As
soon as the appliance is switched on, the display shows the
current relative air humidity. The measurement is accurate
to +/- 5%.
B) Setting the humidity output
The appliance is fitted with a hygrostat. This measures the
relative air humidity and automatically switches the appli-
ance off when the desired value is reached. When switching
the unit on use the rotary switch (A), the desired value is
preset to 55%.

«Tank empty»
The water level is easy to see thanks to the transparent
water tank. The display on the appliance also shows when
the unit should be refilled with water. If the water level
falls below the minimum level, the appliance automatically
switches off. A red blinking symbol (F) appears on the dis-
play. When water is added, symbol F disappears and the
appliance continues operating.
Warning: When lifting the upper part off the housing, the
appliance also switches off. In this case, the red blinking F
symbol will also appear on the display. Only when the up-
per part is replaced on the base does symbol F disappear
and the appliance resumes operation.
