Address setting procedure 1
1
Energize indoor units
fi
rst, and then energize outdoor units.
2
About one minute after energizing the outdoor units, con
fi
rm that the 7-segment display on the
interface P.C. board of the header outdoor unit indicates
U. 1. L08
. The U.1. will be
fl
ashing.
3
Press SW 15 to start the automatic address setting.
It normally takes 5 minutes, but may takes as long as 10 minutes to complete the auto address setting for 1
refrigerant line.
4
The 7 segment display will indicate
Auto 1
→
Auto 2
→
Auto 3
.
When the address sequence has covered all the fan coils for a refrigerant line auto - the 7
segment display will indicate
U. 1.
fl
ashing.
When the
fl
ashing stops and the display indicates
U. 1.
without
fl
ashing, the address setting is
complete.

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.
