(The inter-unit control wires are not connected to multiple
refrigerant systems.)
Indoor unit addresses can be set without operating the
compressors.
(1) Automatic Address Setting from the Outdoor Unit
1 On the outdoor main unit control PCB, check that the
system address rotary switch (S002) is set to "1" and that
the DIP switch (S003) is set to ON
