REQUIREMENT
• When a group control is performed over multiple
refrigerant systems, be sure to turn on the power
supplies to all of the indoor units connected , so that
the address set-up can be completed correctly.
• If turning on the power for each refrigerant system
to set up the addresses, a header indoor unit must
be set for each system. Therefore, an alarm code
"L03" (Duplicated header indoor units) will be
displayed during in operation after the address
setup has been completed. In this case, change the
group address using the wired remote controller so
that only one header indoor unit is set-up.
