• When a group control is performed over the
multiple refrigerant lines, be sure to turn on the
power supplies of all the indoor units connected

• If turning on the power for each refrigerant line
to set up address, a header indoor unit is set for
each line. Therefore, an alarm code “L03”
(Duplicated indoor header units) is output in
operation after address setup. In this case,
change the group address from the wired
remote controller for only one header unit is set
