*Do not short-circuit the automatic address setting pin (CN51) again while automatic address setting is in progress. Doing so will cancel the setting operation and will cause LEDs 1 and 2 to turn OFF.

*When automatic address setting has been successfully completed, both LEDs 1 and 2 turn OFF.

*LED 1 is D042. LED 2 is D043.

*If automatic address setting is not completed successfully, refer to the table below and correct the problem. Then perform automatic address setting again.

After the power is turned ON (and automatic address setting is not in progress), no communication with the indoor units in that system is possible.

After the power is turned ON (and automatic address setting is not in progress), 1 or more indoor units are confirmed in that system; however, the number of indoor units does not match the number that was set.

Alternating

Automatic address setting is in progress.

Automatic address setting completed.

	At time of automatic address setting, the number of indoor units did not match the number that was set.
Simultaneous	(when indoor units are operating) indication appears on the display.
Alternating	Refer to Table of Self-Diagnostic Functions and Description of Alarm Displays.

Request concerning recording the indoor/outdoor unit combination Nos.

After automatic address setting has been completed, be sure to record them for future reference.

List the outdoor unit system address and the addresses of the indoor units in that system in an easily visible loca- tion (next to the nameplate), using a permanent marking pen or similar means that cannot be erased easily.

Example: (Outdoor) 1 – (Indoor) 1-1, 1-2, 1-3…

(Outdoor) 2 – (Indoor) 2-1, 2-2, 2-3…

These numbers are necessary for later maintenance. Please be sure to indicate them.
