SWITCHING UNIT
The switching unit status is directly displayed by LED diodes on the switching unit´s cover in
a following way.

−
constant shining: equipment under pressure, unsuccessful radio communication,
control unit out of operation or out of impact
power supply status and status of radio communication between
the equipments
−
blinking: equipment under pressure, successful radio communication
blue: dehumidification status. When shining, the fan relay is being switched on.
After a 4 minute layoff the compressor´s relay is switched on too.
yellow:
heating status. When shining, the heating relay as well as the fan relay are
being switched on.
white:
defrosting status. The detector of ice coating on the evaporator reacted. Only
the fan operates.

DATA TRANSMISSION INTO THE MEMORY PEN
If you wish to transfer the measured and saved data for diagnosing the equipment operation,
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 rest of the
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.
