● Name And Function Of Each Switch On Outdoor Unit Control PC Board
• Mode Select switch
Changes to the cooling or heating mode. (Main outdoor unit is only usable.)
(3P, Black) (CN085)
During normal drive When the cooling side is short-circuit, all indoor units change to cooling mode.
When the heating side is short-circuit, changes to all heating mode.
• Auto Address pin Short-circuit for 1 second or longer.
(2P, White) (CN054) When the short-circuit remains in effectfor more than 1 second during auto address, the auto
address is interrupted.
• Test Run pin When set to short-circuit, changes to the test run mode.
(2P, White) (CN049) (The test run mode is automatically cancelled after an hour.)
When short-circuit is cancelled, the test run mode is cancelled.
• RC socket Connects to the outdoor unit maintenance remote control and the content of an alarm message
(3P, Blue) (CN077) will be checked.
• Drive pin When the pulse signal applied after short-circuit, all indoor units within the same series will be
(2P, White) (CN052) operated.
• Stop pin When the pulse signal applied after short-circuit, all indoor units within the same series will be
(2P, White) (CN053) stopped.
(When set to short-circuit, the remote control from the indoor unit can not be operated.)
• Vacuum pin
Used for vacuuming the outdoor unit.
(2P, White) (CN050)
Socket for Snow Area
• Snow socket
Used for installing the snow sensor
(3P, Red) (CN057)

(1) 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
ON ON
(3 units), and set the unit No. DIP switch (S007) to
1 2 3
OFF
2. On the No. 2 (sub) unit control PCB, set the unit No. switch (S007) to
On the No. 3 (sub) unit control PCB, set the unit No. switch (S007) to
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 ON ON "0." (These are the settings at the time of factory shipment.)

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 (CN054) for 1 second or longer, then release it.
(Communication for automatic address setting begins.)
* To cancel, again short-circuit the automatic address pin (CN054) for 1 second or longer, then release it.
The LED that indicates that automatic address setting is in progress turns OFF and the process is stopped. Be sure
to perform automatic address setting again.
(Automatic address setting is completed when LEDs 1 and 2 on the outdoor main unit control PCB turn OFF.)
7. Operation from the remote controllers is now possible.
* To perform automatic address setting from the remote controller, perform steps 1 to 5, then use the remote controller and
complete automatic address setting.
● Refer to "Automatic Address Setting from the Remote Controller."
