Basic wiring diagram: Example (2)
• If link wiring is used
* When multiple outdoor main units exist, remove the socket that is used to short-circuit the terminal plug (CN003) from all outdoor unit
PCBs except for 1. Alternatively, move the sockets to the "OPEN" side.

<Case 1> Automatic Address Setting (no compressor
operation)
●
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 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.)
2 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"
ON
ON
, and set the rotary switch (S004) to "3."

3 To set the number of outdoor units, on the outdoor main
unit control PCB set the No. of outdoor units DIP switch
ON
ON
(S006) to (3 units).
1 2 3 OFF
4 On the No. 1 (main) unit control PCB, set the unit No.
switch (S007) to ON (unit No. 1).

On the No. 2 (sub) unit control PCB, set the unit No. switch
ON
(S007) to (unit No. 2).

On the No. 3 (sub) unit control PCB, set the unit No. switch
ON
(S007) to (unit No. 3).

5 At the outdoor main unit where all indoor and outdoor unit
power has been turned ON, short-circuit the automatic
address pin (CN100) for 1 second or longer, then release
it.
↓
(Communication for automatic address setting begins.)
↓
* To cancel, again short-circuit the automatic
address pin (CN100) for 1 second or longer,
then release it.
The LED that indicates 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.)
↓
6 Next turn the power ON only for the indoor and outdoor
units of the next (different) system. Repeat steps 1 – 5 in
the same way to complete automatic address settings for
all systems.
↓
7 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.
●
Refer to "Automatic Address Setting from the Remote
Controller."
Fig. 7-6
<Case 2> Automatic Address Setting in Heating Mode
●
Indoor and outdoor unit power cannot be turned ON for each
system separately.
In the following, automatic setting of indoor unit addresses is
not possible if the compressors are not operating. Therefore
perform this process only after completing all refrigerant
tubing work.

2 Turn the indoor and outdoor unit power ON at all systems.

↓
3 To perform automatic address setting in <Heating mode>,
on the outdoor main unit control PCB in the refrigerant
system where you wish to set the addresses, short-circuit
the automatic address pin (CN100) for 1 second or longer,
then release it.
(Be sure to perform this process for one system at a time.
Automatic address settings cannot be performed for more
than one system at the same time.)
↓
(Communication for automatic address setting begins, the
compressors turn ON, and automatic address setting
in Heating mode begins.)
(All indoor units operate.)
↓
* To cancel, again short-circuit the automatic
address pin (CN100) for 1 second or longer,
then release it.
The LED that indicates 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 the
compressors stop and LEDs 1 and 2 on the outdoor main
unit control PCB turn OFF.)
↓
4 At the outdoor main unit in the next (different) system,
short-circuit the automatic address pin (CN100) for 1
second or longer, then release it.
↓
(Repeat the same steps to complete automatic address
setting for all units.)
↓
5 Operation from the remote controllers is now possible.
* To perform automatic address setting from the remote
controller, perform steps 1 and 2, then use the remote
controller and complete automatic address setting.

Refer to "Automatic Address Setting from the Remote
Controller."
