CAUTION
The main address must be set to a value in the range 0 to 15. If you set other values, communication error will occur.
If any of SEG5 and SEG6 is set to a value in the range A to F, the main address of the indoor unit does not change.
If SEG3 is set to 0, the indoor unit maintains the existing main address even if SEG6 is set to a new value.
If SEG9 is set 0, the indoor unit maintains the existing RMC address even if SEG11 and SET12 are set to new values.

2 Set an address for each indoor unit using the remote
control, according to your air conditioning system plan,
by referring to the following table and by following the
steps in Common steps for setting the addresses and
options on page 20.
The indoor unit addresses (main and RMC
addresses) are set to 0A0000-100000-200000-
300000 by default.
If indoor units and outdoor units match 1:1, you
don't need to set the main address because it is
automatically set by the outdoor unit.
If you are using on or off controller, set RMC
address.
