C) Timer
Using button C, the operation time can be set – adjustable
between 1 and 8 hours, or continuous operation (CO).
Symbol G
shows the operating period that has been set
(1h/2h/3h/4h/5h/6h/7h/8h/CO). The display will automati

D) Controlling mist output and Evaporator
output
By repeatedly pressing button D you can control the mist

Symbol H
shows which of the three levels (low/
medium/high) you have selected.
E) Operation with pre-heating
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 80 °C before entering the nebuliser space.
It takes approx. 10 to 15 minutes for the water in the base
to warm up. The mist now leaves the nebuliser space at a
pleasant temperature of 40 °C. The advantage of this is
that the room temperature does not drop and, in addition, it
significantly improves the water quality maintenance.

and pre-set target value. By pressing the button twice, the
sleep function is switched on (

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.
A) On/Off Dial and Display Dimmer

(by holding down).
