8-4. Address Setup

After power-ON, set up the indoor address from the interface P.C. board of the header unit.

(The address setup operation cannot be performed by power-ON only. )

8-4-1. Cautions

1. It requires approx. 5 minutes usually for 1 line to automatically set up address.

However in some cases, it may require maximum 10 minutes.

2. It is unnecessary to operate the air conditioner for address setup.

3. Manual address setup is also available besides automatic setup.

Automatic address: Setup from SW15 on the interface P.C. board of the header unit

Manual address: Setup from the weird remote controller.
(For details, refer to section “8-4-3. Address setup procedure”)

Operation and check contents

Turn on power of indoor unit in refrigerant line to which address is set up.

Turn on power of all the outdoor units in refrigerant line to which address is set up.

Check that [L08] is displayed on 7-segment display [B] on the interface P.C. board of the header
unit in the system to which address is set up.

Confirm the corresponding items in “8-4-3 Address setup procedure”, and then set up address
according to the operation procedure.
(Be sure that the setup operation may differ in group control or central control.)
Note) Address cannot be set up if switches are not operated.

• After address setup, [U1] is displayed in 7-segment display section.

• For follower outdoor units, [U2] to [U4] are displayed in 7-segment display [A].

• If an error code is displayed in 7-segment display [B], remove the cause of trouble referring to

“9. Troubleshooting”.

Using 7-segment display function, check the system information of the scheduled system.
(This check is executed on the interface P.C. board of the header unit.)
