Automatic Addressing
The address of indoor units would be set by Automatic Addressing
- Wait for 3 minutes after supplying power.
(Master and Slave outside unit s, indoor units)
- Press RED button of the outside unit s for 5 seconds. (SW01C)
- 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 30 seconds on 7-segment LED of the outside unit PCB
- Numbers of connected HR units whose addressing is completed are in-
dicated for 10 seconds on 7-segment LED of the outside unit PCB
- After completing addressing, address of each indoor unit is indicated
on the wired remote control display window. (CH01, CH02,
CH03, ……, CH06 : Indicated as numbers of connected indoor units)

CAUTION
• In replacement of the indoor unit PCB, always perform Automatic
addressing setting again (At that time, please check about using
Independent power module to any indoor unit.)
• If power supply is not applied to the indoor unit, operation error
occur.
• Automatic Addressing is only possible on the master Unit.
• Automatic Addressing has to be performed after 3 minutes to im-
prove communication.

Automatic pipe detection
1. Turn No.1 of SW02M of HR unit PCB off.
2. Confirm that the setting of No.2, 3 of SW02M corresponds with the
number of indoor units.
3. Reset the power of HR unit PCB
4. Master unit PCB DIP switch on : No.5

9. Operated after 88 is displayed on 7-SEG of the outside unit main
PCB.
10. Pipe detection proceed.
11. 5~30 minutes are required depending on the number of the indoor
units and outdoor temperature.
12. The number of the indoor units installed is displayed on 7-SEG of
the outside unit main PCB for about 1 minute
- For a HR unit, the number of the indoor units connected to each
HR unit is displayed.
- '200' is displayed in case of auto pipe detection error, and auto de-
tection is completed after '88' is disappeared.
* Auto pipe detection function : the function that sets connection re-
lationship automatically between the indoor unit and HR unit.
