Product control by the user

PRODUCT CONTROL BY THE USER

− Rotary wheels with confirmation function (when pressing)

The control unit has got the following control elements

− Display unit

− Air temperature

In a basic status the unit displays:

− Set requested relative air humidity

− Measured relative air humidity

− Actual date and accurate time display in the bottom line

− Displaying the following informational icons in the upper line: radio signal presence,

dehumidification, heating, defrosting, device failure, battery change indicating icon

SETTING OF THE REQUESTED HUMIDITY

Set the requested humidity by wheel revolution. The set value can be monitored on the display.
During the setting the lighting is switched on for a certain time. It is also possible to tur n on the
lighting for monitoring the measured values, by pushing the wheel. This does not need any
setting changes. The lighting function is activated only in case of permitting it in the device´s
settings.

SETTING OF THE REQUESTED TEMPERATURE

Press the wheel in the requested humidity display mode. The lighting will turn on. During a time
period of the lighting press the wheel one more time. (In case the lighting function is not
permitted on your device, press the wheel only once.)

The requested temperature is shown down, on the left part of the display. Set the requested
temperature by wheel revolution. The set value can be monitored on the display. During the
setting the lighting is on for a c e rt ai n t im e. It is also possible to turn on the lighting for monitoring
the measured values, by pushing the wheel. This does not need any setting changes. The
lighting function is activated only in case of permitting it in the device´s settings.

Settings

DATE AND TIME SETTING

Press the wheel in the requested temperature display mode – the lig hting will switc h on. During
a time period of the lighting press the wheel one more time. (In case the lighting function is not
permitted on your device, press the wheel only once.)

The accurate time will be shown on the display by big numerals. By wheel revolution set hour
and then by pressing it confirm the setting. The setting of minutes, day, month, year and date is
done in a similar way.

After conforming the year by pressing the wheel you will return to the requested humidity display
mode.

SCREEN SAVER

After a certain time of inactivity the measuring unit turns off the display due to the batteries´
energy saving. Meanwhile the measuring and control functions stay active. If the screen saver i s
active, there will be an arrow showing towards the wheel displayed for a short time and in
regular intervals, or the indicator located under the display blinks - depending on the set device
parameters.

It is possible to return to the basic state anytime by pressing the wheel.
The screen saver function is activated only in case of permitting in the device settings.

BATTERY CHANGE

The device will signalize a need of battery change by showing a discharged battery icon in the
upper part of the screen. In case the screen saver is switched on, this icon will blink
simultaneously with the arrow in the left part of the display or the indicator light of the saver will
blink twice.

Batteries – two alkaline pencilling batteries AA are accessible after the plastic cover removing.
Carefully remove the control wheel with a small, thin object (i.e. with a knife) in a following way:
Insert the knife under the wheel from the right hand side and then pull it toward yourself gently.
Grasp the plastic cover and by pulling the bottom part release it and then remove it. Change

the batteries by paying attention at the right polarity. Mount the cover. After the change set the
accurate time and date.

It is recommended to use lithium AA ,,Energizer Ultimate Lithium´´ batteries (sometimes
labelled as Energizer L91). These batteries last longer in comparison with the usual alkaline
batteries AA. The batteries are not accessible from another manufacturers, as Energizer
company has got a patent at its technology.
