switch (S003) is set to

 

 

 

“0.” (These are the settings at the time of factory shipment.)

 

 

 

1 2 OFF

4.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

ON ON

No. of indoor units DIP switch (S005) to

 

 

 

 

 

“1.” and set the rotary switch (S004) to “0.”

 

 

 

 

1 2 3 OFF

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.

zRefer to “Automatic Address Setting from the Remote Controller.”
