h. The group setting operations among the multiple indoor units is done by the remote controller (RC) after the electrical power has been turned on.
i.
When the centralized remote controller is connected to the system, set centralized control switches (SW2-1) on control boards in all outdoor units (OC, OS) to "ON".
*1 OC and OS of the outdoor units in the same refrigerant system are automatically identifi ed. They are identifi ed as OC and OS in descending order of capacity (If the
capacity is the same, they are identifi ed in the ascending order of their address number).

Use the most recent address within the same group of indoor units. With an R2 system with sub BC
controllers, set the indoor unit address in the following order:
1 Indoor units connected to the main BC controller
2 Indoor units connected to BC sub controller 1
3 Indoor units connected to BC sub controller 2
Set the indoor unit addresses so that all the addresses of 1 are smaller than those of 2, and that all
the addresses of 2 are smaller than those of 3.
01 to 50
Use an address, other than that of the IC (Main) from among the units within the same group of indoor
units. This must be in sequence with the IC (Main)
51 to 100
Set the addresses of the outdoor units in the same refrigerant system in the order of sequential
number. OC and OS are automatically identifi ed. (*1)
51 to 100
Outdoor unit address plus 1. When the set indoor unit address duplicates the address of another
indoor unit, set the new address to a vacant address within the setting range.
51 to 100
Lowest address within the indoor units connected to the BC controller (sub) plus 50
101 to 150
Set at an IC (Main) address within the same group plus 100
151 to 200
Set at an IC (Main) address within the same group plus 150
