Test Run Procedure
Use caution when making the settings. If there
are duplicated system addresses setting at
R.C. ADD switch, or if the settings for the Nos.
of the indoor units are not consistent, an alarm
will occur and the system will not start.
These settings are not made on the indoor unit

These settings are not necessary at all outdoor units other than the No. 1 unit. At these units, set only the unit number.
<General Explanation of the Switches on the Outdoor Unit Control PCB>
MODE (2P, white) Changes the operating mode (heating/cooling). (Can be used only at the main unit.)
(CN101) During normal operation: Short-circuiting these pins once will change all indoor units
in that system to either cooling mode or heating mode.
During automatic address setting: When the pins are not connected, the mode is
heating mode.
A. ADD (2P, white) Short-circuited for 1 s or longer →Automatic address setting begins when the pins
(CN100) are released. Short-circuiting these pins for 1 s or longer while automatic address
setting is in progress interrupts automatic address setting.
CHK (2P, white) When these pins are short-circuited, the mode is test run mode. (Test run mode is
(CN023) automatically canceled after 1 hour.) When the pins are released, test run mode is
canceled.
RC (3P, blue) The outdoor unit maintenance remote controller can be connected here to check the
(CN006) alarm details.
RUN (2P, white) Short-circuit these pins and apply a pulse signal to start all indoor units in that system.
(CN103)
STOP (2P, white) Short-circuit these pins and apply a pulse signal to stop all indoor units in that system.
(CN104) (If the pins are left short-circuited, it will not be possible to start operation from the
indoor unit remote controllers.)
AP (2P, white) These pins are used when applying vacuum to the outdoor unit.

Automatic Address Setting from the Outdoor Unit
1. To set the number of outdoor units, on the outdoor main unit control PCB set the No. of outdoor units DIP switch (S006) to
(3 units), and set the unit address No. switch (S007) to (unit No. 1 – main outdoor unit).
2. On the No. 2 (sub) unit control PCB, set the unit address No. switch (S007) to (unit No. 2).
On the No. 3 (sub) unit control PCB, set the unit address No. switch (S007) to (unit No. 3).
3. On the outdoor main unit control PCB, check that the system address rotary switch (S002) is set to “1” and that the DIP
switch (S003) is set to “0.” (These are the settings at the time of factory shipment.)
4. To set the number of indoor units that are connected to the outdoor unit to 10, on the outdoor main unit control PCB set the No.
of indoor units DIP switch (S005) to “1,” and set the rotary switch (S004) to “0.”
5. Turn ON the power to the indoor and outdoor units.
6. On the outdoor main unit control PCB, short-circuit the automatic address pin (CN100) for 1 second or longer, then release it.

* When multiple outdoor main units exist, remove the socket that
is used to short-circuit the terminal plug (CN003) from all
outdoor main unit PCBs except for one unit.
Alternatively, move the sockets to the “OPEN” side.
It is not necessary to change the terminal plug connecting
socket on the PCBs of any units other than the main outdoor
unit.
Leave the socket

Indoor and outdoor unit power can be turned ON for each system separately.
Indoor unit addresses can be set without operating the compressors.
Automatic Address Setting from Outdoor Unit
1. On the No. 1 (main) unit control PCB, set the unit address No. switch (S007) to (unit No. 1 – main outdoor unit).
On the No. 2 (sub) unit control PCB, set the unit address No. switch (S007) to (unit No. 2).
On the No. 3 (sub) unit control PCB, set the unit address No. switch (S007) to (unit No. 3).
2. To set the number of outdoor units on the outdoor main unit control PCB, set the No. of outdoor units DIP switch (S006) to
(3 units).
3. On the outdoor main unit control PCB, check that the system address rotary switch (S002) is set to “1” and that the DIP
switch (S003) is set to “0” . (These are the settings at the time of factory shipment.)
4. To set the number of indoor units that are connected to the outdoor unit to 13, on the outdoor main unit control PCB set the
No. of indoor units DIP switch (S005) to “1” , and set the rotary switch (S004) to “3.”
5. Turn on power to all indoor and outdoor units in the system.
6. Short-circuit the automatic address pin at the outdoor main unit (CN100) for 1 second or longer, then release it.
↓
(Communication for automatic address setting begins.)
↓
(Automatic address setting is completed when LEDs 1 and 2 on the outdoor main unit control PCB turn OFF.)
↓
7. Next turn the power ON only for the indoor and outdoor units of the next (different) system. Repeat steps 1 – 4 in the same
way to complete automatic address settings for all systems.
↓
8. Operation from the remote controllers is now possible.
* To perform automatic address setting from the remote controller, perform steps 1 – 4, then use the remote controller and
complete automatic address setting. For the necessary procedure, refer to “Automatic Address Setting from Remote
