1.Refer to the wiring boards of the indoor units for details on wiring of each indoor unit.
2.The transmission line is two-wire type and has no polarity.
3.Mark shows the terminal board,mark the connector .Symbols in parentheses () show the colors of connectors.
4.Self-diagnosis function
The indoor and outdoor units can be diagnosed automatically using the self-diagnosis switch(SW1) and LD1(LED indication)
found on the multi-controller of the outdoor unit.
LED indication : Set all contacts of SW1 to OFF.
