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
6	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.
