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 refer-
ring to the following table and by following the steps in Common steps for setting the addresses and options on page
4-1.

• 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.
