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.

Automatic address setting is in progress.
