CAUTION
• In replacement of the indoor unit PCB, always perform Automatic
addressing setting again (At that time, please check about using
Independent power module to any indoor unit.)
• If power supply is not applied to the indoor unit, operation error occur.
• Automatic Addressing is only possible on the master Unit.
• Automatic Addressing has to be performed after 3 minutes to im-
prove communication.
!
The Procedure of Automatic Addressing
• Automatic addressing setting end
Numbers of indoor unit connection set whose
addressing is completed are indicated for 30seconds
on 7-segment LED after completing setting
Indoor address number is displayed on wired remote control or
indoor unit display window. It is not an error message, will
disappeared when on/off button is pressed on remote control
ex) Display of 01, 02, ..., 15 means connection of 15 indoor units
and Automatic addressing is completed normally.

- Wait for 3 minutes after supplying power.
(Master and Slave outdoor units, indoor units)
- Press RED button of the outdoor units for 5 seconds. (SW01C)
- A “88” is indicated on 7-segment LED of the outdoor unit PCB.
- For completing addressing, 2~7 minutes are required depending on
numbers of connected indoor units
- Numbers of connected indoor units whose addressing is completed are
indicated for 30 seconds on 7-segment LED of the outdoor unit PCB
- After completing addressing, address of each indoor unit is indicated
on the wired remote control display window.
(CH01, CH02, CH03, ……, CH06 : Indicated as numbers of connected
indoor units)
Checking the setting of outdoor units
Checking according to dip switch setting
- You can check the setting values of the Master outdoor unit from the
7 segment LED. The dip switch setting should be changed when the
