The Procedure of Automatic Addressing

Power On
Waiting 3 minutes
Press RED Button for
5 seconds (SW01C)
Automatic addressing process start
7-segment LED = 88
Don't press RED Button
(SW01C)
• Automatic addressing process end
Waiting about 2~7 minutes Numbers of indoor unit connected are indicated for 30
seconds on 7-segment LED after completing process.
NO
7-segment LED
= 88
YES
Indoor address number is displayed on wired remote controller or
indoor unit display window. It is not an error message, will
disappeared when on/off button is pressed on remote controller
ex) Display of 01, 02, ..., 15 means connection of 15 indoor units
OK and Automatic addressing is completed normally.
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 has to be performed after more than 3
minutes to improve indoor unit communition when initial power is
supplied.
• Please be sure that all the DIP switch (1~7) of master outdoor unit is
OFF before Automatic Addressing setting
