5-1. Indoor unit
1) Before installing the indoor unit, assign an address to the indoor unit according to the
air conditioning system plan.
2) The address of the indoor unit is assigned by adjusting MAIN(SW02) and RMC(SW01)
rotary switches.
3) The MAIN address is for communication between the indoor unit and the outdoor unit.
Therefore, you must set it to operate the air conditioner properly.
4) It is required to set the RMC address if you install the wired remote controller and/or the
centralized controller.
5) If you install optional accessories such as the wired remote controller, centralized controller,
etc. see an appropriate installation manual.
6) If an optional accessory is not installed, you do not have to set the RMC address.
However, adjust K1 and K2 switches of the SW03 DIP switch to "ON" position in this case.
7) Set the MAIN address by adjusting the rotary switch(SW02)
from 0 to F. Each indoor unit connected to the same outdoor unit
must have different address.
i. e. If an indoor unit does not have an optional accessory
and its MAIN address is "4"
