Address setting method
Set the indoor unit you want to make the master unit in the same group to the mini-
mum address, and sequentially set the indoor unit addresses in the same group.
Min.indoor unit address in same refrigerant No.50 unit.
Outdoor unit address in same refrigerant No.1 unit.
However, for Sub-BC controller, minimum indoor unit address that connects the lo-
cal refrigerant 50.
Same address as indoor unit master unit
Set to the minimum indoor unit master address in the same group + 100.
Address setting is unnecessary.
After setting all the indoor units, set an arbitrary address.
