9-21. Automatic Address Setting

9-21-1. Basic wiring diagram

●

Link wiring

N OT E

●

A terminal plug (black) is attached to each of the

outdoor unit control PCBs. At only one outdoor unit,
leave the terminal plug short-circuit socket on the “Yes”
side. At all the other outdoor units, change the socket
(from “Yes” to “No”).

●

A maximum of 8 indoor units can be connected to 1 remote

controller for group control.

Automatic address setting from the outdoor unit

Case 1

●

If the power can be turned ON separately for the indoor and

outdoor units in the system, the indoor unit addresses can be
set without running the compressor.

(1) Turn on the indoor and outdoor unit power for refrigerant

system 1.
Press and hold the automatic address setting button
(black) for 1 second or longer at the outdoor unit where the
power was turned ON.

↓

Communication for automatic address setting begins.

↓

LED 1 and 2 on the outdoor unit control PCB blink
alternately, and turn OFF when address setting is
completed.

↓

<Approximately 4 – 5 minutes are

required.>

(2) Next, turn ON the power only at the indoor and outdoor

units in a different system. Press the automatic address
setting button (black) on the outdoor unit.

↓

LED 1 and 2 on the outdoor unit control PCB blink
alternately, and turn OFF when address setting is
completed.

↓

Repeat the same procedure for each system and complete
automatic address setting.

↓

(3) Operation using the remote controller is now possible.

Case 2

●

If the power cannot be turned ON separately for the indoor

and outdoor units in the system:
The compressors must be run in order to automatically set
the indoor unit addresses. Therefore perform this step after
completing the refrigerant tubing work.

(1) Turn ON the power to the indoor and outdoor units in all

refrigerant systems.

↓

When setting addresses in cooling mode

(2) Short-circuit the mode-change pin at the outdoor unit

where automatic address setting will be performed. Then
press the automatic address setting button (black).

↓

When setting addresses in heating mode

(2) Press the automatic address setting button (black) at

the outdoor unit where automatic address setting will be
performed.

↓

(3) LED 1 and 2 blink alternately. The compressors begin

running in Cooling (or Heating) mode. Communication for
automatic address setting begins, using the temperature
changes at the indoor units.

↓

Address setting is completed when the compressors stop
and the LED indicators turn OFF. <Approximately 15
minutes is required for 1 system.>
If address setting fails, LED 1 and 2 blink simultaneously
and the alarm contents are displayed at the remote
controller.

(4) After 1 system is completed, be sure to press the

automatic address setting button (black) at the other
outdoor units to complete automatic address setting in the
same way for each system.

(5) Operation using the remote controller is now possible.

Automatic address setting using the remote controller

Case 3

●

If the power can be turned ON separately for the indoor and

outdoor units in each system (indoor unit addresses can be
set without running the compressor):

Individual system automatic address setting: Display item code
“A1”.

(1) Press the remote controller timer time

button and

button simultaneously.
(Hold for 4 seconds or longer.)

↓

(2) Then press either the temperature setting

button.

(Confirm that the item code is “A1”.)

↓

(3) Use either the

button to select the

outdoor unit to perform automatic address setting for. Then
press the

button.

(“R.C.1” is displayed, and automatic address setting is
performed for refrigerant system 1.)
When automatic address setting for system 1 is completed,
the units return to normal stopped status.
<Approximately 4 – 5 minutes are required.>

During automatic address setting, “SETTING” blinks on the
remote controller display. This display disappears when
address setting is completed.

Case 4

●

If the power cannot be turned ON separately for the indoor

and outdoor units in each system:
(The compressors must be run in order to automatically set
the indoor unit addresses. Therefore perform this step after
completing the refrigerant tubing work.)

All-systems automatic address setting: Display item code “AA”.

(1) Press the remote controller timer time

button and

button simultaneously. (Hold for 4 seconds or longer.)

↓

(2) Next press the

button.

(Automatic address setting is performed in sequence for
all outdoor units from No. 1 to No. 30. When automatic
address setting is completed, the units return to normal
stopped status.)
<Approximately 15 minutes is required for each system.>

↓

During automatic address setting, “SETTING” blinks on the
remote controller display. This display disappears when
address setting is completed.
