REQUIREMENT
• 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 in
a group in the time of address setup.
• 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 so that only one header unit is set up.
