REQUIREMENT
• When a group control is performed over the
multiple refrigerant systems, 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
system 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
indoor unit is set up.
