After turned on power (not during auto address setting), it is entirely impossible to communicate with
the indoor unit in the system.
After power is turned on (and auto address setting is not in progress), one or more indoor units are
conrmed in that system; however, the number of indoor units does not match the number that was
set.
This status remains even if the indoor unit address (indoor EEPROM item code : 13) is set more than
13 indoor units. In this case, be sure to set the indoor unit address less than 12.
