- A "88" is indicated on 7-segment LED of the outside unit PCB.
- For completing addressing, 2~7 minutes are required depending on
numbers of connected indoor units
- Numbers of connected indoor units whose addressing is completed are
indicated for 20 seconds on 7-segment LED of the outside unit PCB
- After completing addressing, address of each indoor unit is indicated
