TROUBLESHOOTING
In addition to the CODE No. on the remote controller of an indoor unit, you can diagnose failure type of an outdoor unit by
checking the 7-segment display on the interface P.C. board.
Use the function for various checks.
Set every dip switch to OFF after checking.

7-Segment display and check code
* If a check code has an auxiliary code, the display indicates the check code for three seconds and the auxiliary
code for one second alternately.
Check code (indicated on the 7-segment display on the outdoor unit)
Indicated when SW01 = [1], SW02 = [1], and SW03 = [1].
