(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 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 6 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. 6-8
