• In replacement of the indoor unit PCB, always perform Automatic
addressing setting again (At that time, please check about using In-
dependent 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
Power On
Waiting 3 minutes
Press RED Button for 5 sec.
(SW01C)
Automatic addressing start
7-segment LED
= 88
Don't press RED Button
(SW01C)
• Automatic addressing setting end
Numbers of indoor unit connection set whose
addressing is completed are indicated for 30seconds
Waiting about 2~7 minutes
on 7-segment LED after completing setting
NO
7-segment LED
= 88
YES
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
OK
and Automatic addressing is completed normally.

Group Number setting
Group Number setting for Indoor Units
- Confirm the power of whole system(Indoor Unit, Outdoor Unit) is
OFF, otherwise turn off.
- The communication cables connected to CEN.A and CEN.B terminal
should be connected to central control of Outdoor Unit with care for
their polarity (A-A, B-B ).
- Turn the whole system on.
- Set the group and Indoor Unit number with a wired remote control.
- To control several sets of Indoor Units into a group, set the group ID
from 0 to F for this purpose.
