*1 In case of group control over refrigerant systems, automatic address setting is available only when all indoor units
connected to a group control are turned on during address setting.
If an automatic address setting is conducted under condition of power-ON only in the refrigerant system in which
address set up, it will cause the error code “L03” (Duplicated header indoor units) because header indoor units exit
for each refrigerant system. In this case, change the group address by the wired remote controller so that only one
indoor unit becomes the header unit in one group control.
