(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 (SW6) to
1 2 3
(3 units), and set the unit No. DIP switch (SW5) to
2 3 1
(unit No. 1 – main outdoor unit).
2. On the No. 2 (sub) unit control PCB, set the unit No. switch (SW5) to
3 2 1
(unit No. 2).
On the No. 3 (sub) unit control PCB, set the unit No. switch (SW5) to
1 2 3
(unit No. 3).
3. On the outdoor main unit control PCB, check that the system address rotary switch (SW1) is set to “1” and that the DIP
switch (SW2) is set to
1 2
“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 (SW4) to
2 3 1
“1,” and set the rotary switch (SW3) 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 (CN30) for 1 second or longer, then release it.
(Communication for automatic address setting begins.)
* To cancel, again short-circuit the automatic address pin (CN30) 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.”
