REQUIREMENT
• When 2 or more refrigerant lines are controlled as a group (using, 1 remote control), be sure to turn on all the
indoor units in the group before setting the addresses.
(Note: the group control of more than two refrigerant systems is possible only when all the FS units are single
port type.)
• If the unit address of each refrigerant line is set separately, then the header unit for each line will be set
separately. In this case the remote control will display CODE No. "L03" indicating "indoor header unit overlap"
when the system starts running. When this happens the group address must be changed to make only one unit
the header unit. This operation is done using the wired remote control.
