4. Auto Address Setting
Case 3B Automatic Address Setting in Cooling 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.
Automatic address setting can be performed during Cooling operation.
Automatic Address Setting from Outdoor Unit
1. Perform steps 1 - 4 in the same way as for Case 2 .
5. Turn the indoor and outdoor unit power ON at all systems.
6. To perform automatic address setting in Cooling mode , on the outdoor main unit control PCB in the refrigerant system
where you wish to set the addresses, short-circuit the mode change 2P pin (CN101). At the same time, 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 Cool-
ing 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.)
7. 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.)
8. Operation from the remote controllers is now possible.
* Automatic address setting in Cooling mode cannot be done from the remote controller.
Automatic Address Setting* from the Remote Controller
Selecting each refrigerant system individually for automatic address setting
---Automatic address setting for each system: Item code “A1.”
1. Press the remote controller timer time button and button at the
same time.
(Press and hold for 4 seconds or longer.)
2. Next, press either the temperature setting or button.
(Check that the item code is “A1.”)
3. Use either the or button to set the system No.
to perform automatic address setting.
4. Then press the button.
(Automatic address setting for one refrigerant system begins.)
(When automatic address setting for one system is completed, the sys-
tem returns to normal stopped status.) <Approximately 4 - 5 minutes is
required.>
(During automatic address setting, “SETTING” is displayed on the
remote controller. This message disappears when automatic address
setting is completed.)
5. Repeat the same steps to perform automatic address setting for each
successive system.
