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 and 2 in the same way as for
.
2. Turn the indoor and outdoor unit power ON at all systems.
↓
3. To perform automatic address setting in
, on the outdoor unit control PCB in the refrigerant sys-
tem where you wish to set the addresses, short-circuit the mode change 2P pin (CN50). At the same time,
short-circuit the automatic address pin (CN51) for 1 second or longer, then pull it out. (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 Cooling mode begins.
)
(All indoor units operate.)
↓
(Automatic address setting is completed when the compressors stop and LEDs 1 and 2 on the outdoor unit con-
trol PCB turn OFF.)
4. At the outdoor unit in the next (different) system, short-circuit the automatic address pin (CN51) for 1 second or
longer, then pull it out.
↓
(Repeat the same steps to complete automatic address setting for all units.)
↓
5.
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”
Press the remote controller timer time
button and
button at
the same time. (Press and hold for 4 seconds or longer.)
Next, press either the temperature setting
or
button.
(Check that the item code is “A1.”)
Use either the
or
button to set the system No. to per-
form automatic address setting.
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.)
Repeat the same steps to perform automatic address setting for each successive system.
Cooling mode
Case 1
Case 3
* To cancel, again short-circuit the automatic address pin (CN51) for 1 second or longer, then pull it out.
The LED that indicates automatic address setting is in progress turns OFF and the process is stopped.
