• If link wiring is not used

(The inter-unit control wires are not connected to multiple refrigerant systems.) Indoor unit addresses can be set without operating the compressors.

(1) Automatic Address Setting from the Outdoor Unit
1.	On the outdoor main unit control PCB, check that the system address rotary switch (S002) is set to “1” and that
	the DIP switch (S003) is set to	ON			ON “0.” (These are the settings at the time of factory shipment.)
			1	2	OFF
2.	To set the number of indoor units that are connected to the outdoor unit to 10, on the outdoor main unit control
	PCB set the No. of indoor units DIP switch (S005) to						ON “1,” and set the rotary switch (S004) to “0.”
						ON

OFF

3.	To set the number of outdoor units, on the outdoor main unit control PCB set the No. of outdoor units DIP switch
					ON (2 units), and set the unit No. DIP switch (S007) to
	(S006) to ON							ON					(unit No. 1 – main).

5.Turn ON the power to the indoor and outdoor units.

6.On the outdoor main unit control PCB, short-circuit the automatic address pin (CN100) for 1 second or longer, then release it.

(Communication for automatic address setting begins.)

*To cancel, again short-circuit the automatic address pin (CN100) for 1 second or longer, then release it.

↓The LED that indicates that automatic address setting is in progress turns OFF and the process is stopped. Be sure to perform automatic address setting again.

(Automatic address setting is completed when LEDs 1 and 2 on the outdoor main unit control PCB turn OFF.)

↓

7.Operation from the remote controllers is now possible.

*To perform automatic address setting from the remote controller, perform steps 1 to 5, then use the remote controller and complete automatic address setting.

●Refer to “Automatic Address Setting from the Remote Controller.”
