Setting the indoor unit addresses
Option No. for an indoor unit address: 0AXXXX-1XXXXX-2XXXXX-3XXXXX
Before installing an indoor unit, be sure to set an address for the indoor unit by taking the following steps:
1 Make sure that the power is supplied to the indoor unit. If the indoor unit is not plugged in, it must include a power supply.
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 19.
• 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.
