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.

PRODUCT FUNCTIONS
After inserting the batteries the welcome logo is displayed with a software version and the
equipment´s initialisation starts running. The first measuring and evaluation are performed.
Afterwards the equipment tries to make a radio connection with the switching unit. The time is
set on 12:00, date on 1.1.2009 and in case the connection is made, the first record with these
time details is registered. When performing backward monitoring it is possible to determine the
battery change realization.
The periodical recording of measured values and equipment status gets started. After making
the connection with the switching unit, the data are cyclically and in a set period transmitted into
the switching unit for recording. When the memory is full, the oldest data rewriting gets started.
It is not possible to delete the memory and it is either not possible to stop the recording – by this
the reliability of the equipment´s past status detection is ensured. Just before each record the
radio connection is made and the equipment status is detected.
After the period of measuring set in a ,,6´´ parameter has passed, the air humidity and temperature measuring is realized by an inbuilt sensor. Afterwards these data are evaluated. If it
is important to turn on/off the dehumidification, a radio signal is transmitted into the switching
unit.
In case of manual setting of the requested value the evaluation is also realized and if it is
important to intervene, the radio signal is sent.
In case of power cut of the switching unit, it is detected by the measuring unit only during the
next communication trial. After the power supply renewal, the switching unit´s status is activated
also only during the next communication trial. The time set in the ,,7´´ parameter (record period)
is the longest recovery time in case of constant operation. If the humidity or the requested
temperature gets changes, this time is shorter.
In case of power cut of the measuring unit, the switching unit detects its absence during the
paramet er time 7 + 1 minutes. After this time the switching unit turns off the fan as well as the
compressor (if they were turned on before).
PAREMETERS´CONFIGURATION
For entering into the configuration menu, please keep the service button pressed and at the
same time press the control wheel. The service button is located under the display and is
accessible after removing the plastic cover.

please follow the following instructions:
− Dismount the switching unit´s cover by releasing 4 screws
− Insert the USB pen into the USB connector – the green LED diode blinks and the unit
identifies the USB pen. This status will last for cca. 5 seconds.
− Only the white LED diode lights up – the data transmission starts
− The green LED diode blinks– the date get saved in the pen
− The white LED diode lights up while the green LED diode with USB sign is alight
constantly – the transmission is finished
− Pull out the USB pen from the equipment
− Install the cover by 4 screws.
The data are saved in the pen in the ,,HYGRO.LOG´´ file and are divided from each other by
spaces. The first line is descriptive and the second one describes the fields. The res t of th e
lines contents recordings – each record is in a new line. For further data processing it is
suitable to use a table processor. When loading there should be a ´´space ´´ set as a divider.
