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.

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.

Automatic addressing start

Waiting 3 minutes

Power On

Press RED Button for 5 sec.

- 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)
