A) On/Off Dial 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 illu­ minate 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).

C) Timer

Using button C, the operation time can be set adjusta­ ble 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 automati­ cally 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 pres­ sing 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 tempe­ rature. 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.
