A) On/Off Button and Display Dimmer
By pressing button A once, you can switch the unit on. By
pressing it twice, the dimmer is switched on which auto-
matically dims the display brightness and symbol N
comes on. When changing any settings the display will
illuminate for a few seconds before returning to dimmer
mode. By pressing button A a third time, the unit is switched
off. This button is also used to reset the cleaning indicator
light (by holding down).
B) Hygrostat (setting the humidity level)
By pressing button B you can set the desired humidity level
from 30% to 80% or CO (continuous operation). A relative
humidity between 40 and 60% is recommended. The ac-
curacy of measurement is +/- 5%. The unit will switch off
when the moisture level exceeds the desired setting. During
selection the target value is displayed (symbol DESIRED).
The display will automatically show the current value after
a few seconds (symbol CURRENT).

between 1 and 8 hours or CO (continuous operation).

Symbol G shows the operating period that has been set
(1h/2h/3h/4h/5h/6h/7h/8h/CO). The display will automat-
ically show the current humidity after a few seconds.
D) Mist output (regulating mist output)
By repeatedly pressing button D you can control the mist
output. Symbol H shows which of the three levels (low/
medium/high) you have selected.
E) Operation with pre-heating (warm mist)
Button E is used for switching the pre-heating on and off
(symbol I lights up). As a result, the water is pre-heated
to a temperature of 176 °F (80 °C) before entering the

nebulizer space. It takes approx. 10 to 15 minutes for the
water in the base to warm up. The mist now leaves the
humidifier at a pleasant temperature of 104 °F (40 °C). The
advantage of this is that the room temperature does not
drop and, in addition, it significantly improves the water
quality maintenance.
F) Automatic mode and Sleep mode
The automatic and sleep modes can be activated by press-
ing button F. By pressing the button once, the automatic
function is switched on (symbol J appears on the display),
maintaining the optimum humidity subject to the tem-
perature. Control takes place by means of output quantity
and pre-set target value. By pressing the button twice, the
sleep function is switched on (symbol K appears on the
display), the target humidity is 50 – 65%; the operation time
is set at 6 hours; the heating is switched on and the display
brightness is automatically dimmed. In addition, the output
quantity is also controlled subject to the difference between
the target value and the actual value.
The hygrostat and mist output settings cannot be changed
in either mode. If the buttons B or D are pressed, the unit
will no longer be in auto or sleep mode.

L) Empty indicator
The water level is easy to see, thanks to the transparent
water tank. The appliance also alerts you when the water
tank is empty. The empty indicator is illuminated (symbol L).
Please read the chapter «Filling the tank» for more informa-
tion. The symbol L may stay illuminated for some seconds
with a refilled tank until the base is filled with water.
M) Cleaning indicator
If symbol M «CLEAN» appears on the display, the appliance
should be cleaned as recommended by the manufacturer.
This symbol comes on automatically every 2 weeks,
depending on the level of use. The display can be reset
by holding down button A until the light disappears.
