Automatic address setting using the remote controller
When the outdoor unit shown in “Basic wiring diagram 2” is used for group control of multiple outdoor 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 the tempera- ture setting 
or 
button. (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 example, when selected R.C.1 “R.C.1” is displayed.) Then press the 
button. (Automatic address setting is performed for refrigerant circuit 1.) When automatic address setting for circuit 1 is completed, the system returns to normal stopped status. When automatic address setting for circuit 1 is completed, the system returns to normal stopped status. In the same way, press the remote controller timer time 
button and 
button simultaneously to per- form automatic address setting for a different R.C. (refrigerant circuit) if necessary. Then in the same way as
above (use the 
button to display “R.C.2,” for example), select the next circuit and perform automatic ad- dress setting.
