NOTE
The Item code numbers 11, 12, 13 and 14 can automatically be changed to the appropriate
settings from factory settings listed above by making the auto address settings according to
the connected outdoor unit capacity and the number of indoor units. If needed to reset the
settings after once changed, return all the item codes to the factory shipment-time settings. It is
necessary to set the auto address settings once again.
NOTE
In case of checking and changing before setting up the address settings in group connection,
turn on only the power of the system to be checked and changed. If you turn on the power to all
systems before address settings, the settings of all indoor units may not be seen correctly.
After changing, turn off the power supply within 2 minutes or carry out the auto address setting
procedures immediately. If the power of the system switched on for a while, the auto address
setting may start as a single system and it might not match the multiple systems.
