2-8-3. Automatic address setting using the remote controller
When the outdoor unit shown in “2-8-1. Basic wiring diagram” is used for group control of multiple units, use the
remote controller to perform automatic address setting.
(During automatic address setting, “SETTING” blinks on the remote controller display.)
Press the remote controller timer time button and
button simultaneously. (Hold for 4 seconds or longer.)
Then press the
button. (Item code “AA” appears: All systems automatic address setting.)
(Automatic address setting is performed in sequence for all outdoor units from No. 1 to No. 30.
When automatic address setting is completed, the units return to normal stopped status.)
To select each refrigerant system individually and perform automatic address setting, press the remote controller
timer time
button and button simultaneously. (Hold for 4 seconds or longer.)
Then press either of the temperature setting
/
buttons.
(Item code “A1” appears: Individual system automatic address setting)
Use either the
or
button to select the outdoor unit to perform automatic address setting for.
(R.C.1 is displayed.) Then press the
button. (Automatic address setting is performed for refrigerant system 1.)
When automatic address setting for system 1 is completed, the system returns to normal stopped status.
Again press the remote controller timer time
