C) Timer
Using button C, the operation time can be set - adjustable
between 1 and 8 hours, or continuous operation. Letter G
shows the operating period that has been set (1h/2h/3h/
4h/5h/6h/7h/8h). The display will automatically show the
current value after a few seconds.
D) Controlling mist output and Evaporator
output
By repeatedly pressing button D you can control the mist
output. The LO/ME/HI display (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
(letter 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
(bacteria are killed).
F) Auto/Sleep
The automatic and sleep modes can be activated by pres-
sing button F. By pressing the button once, the automatic
function is switched on (letter J appears on the display),
maintaining the optimum humidity subject to the tempera-
ture. Control takes place by means of output quantity and
pre-set target value. If the sleep function is switched on
(the letter K appears on the display), the target humidity is
60%; the operation time is automatically set at 6 hours; the
heating is switched on. In addition, the output quantity is
also controlled subject to the difference between the target
value and the actual value.

L) Empty indicator
The transparent water tank makes it possible to see the
water level well. Furthermore, the unit shows on the display
(L) when water should be added.
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

ance should be cleaned as recommended by the manufac-
turer. This symbol comes on automatically every 2 weeks,
depending on the level of use. The display can be cancelled
by depressing button A for between 10 and 15 seconds.
