ponent is faulty. Error numbers are product specific. See more in unit manual.
Follow the display leaflet for guidance for usage of the display.
The controller has an integrated SD card reader that can exchange parameters for informa-
tion and editing.
The SD card will overall do two operations:
1 . Store operation logging data
, if an SD card is present. By default the ComboCooler will
log a complete set of operation data once each minut.
If suspecting an operation error, place the SD card into the ComboCoolers SD slot, wait
some minutes, and move the SD card to a computer, where the file can be read with word-
pad or simular.
2 . Changing parameters .
Place an empty SD card in the reader, and the controller stores
the parameter configuration immediately on the card (cc4_cfg.txt)
A. Remove the SD card, place it in a computer, and open the file with wordpad or simular.
B. Edit the parameter needed, without changing any amount of empty spaces. End by
saving the file with the exact same file name.
C. Place the SD card in the combo, and the new configuration will be loaded and initiated
on the fly. No need to reboot.
For a complete guide on changing parameters via SD card, please obtain the advanced CC4
manual, available by request.
