WARNING
1. Execute auto addressing and auto pipe detection again when-
ever the indoor PCB and HR unit PCB is replaced.
• Operation error occurs unless power is applied to the indoor
and HR units.
2. Error No.200 occurs if the number of connected indoor units and
that of scanned indoor units are different.
3. When auto pipe detection fails, complete it with manual pipe de-
tection (see Manual pipe detection).
4. When auto pipe detection addressing is completed normally,
manual pipe detection is not required.
5. If you want to do auto pipe detection again after auto pipe detec-
tion fails, do after reset of outside unit by all means.
6. During 5 minutes after pipe detection is completed, do not turn
off the main unit PCB to save the result of pipe detection auto-
matically.
Manual pipe detection
1. Enter the central control address into each indoor unit using its
wired remote control.
2. Turn No.1 of SW02M of HR unit PCB on.
3. Reset the power of HR unit PCB.
4. On the HR unit PCB, manually set address of each valve of the HR
unit to the central control address of the indoor unit connected to
the valve.
5. Reset the power of outside unit PCB.
6. The number of the indoor unit installed is displayed after about 5
minutes.
Ex) HR ➠ The number of the indoor
7. Reset the power of outside unit PCB, HR unit.
8. Manual pipe detection is completed
!
WARNING
1. In case that central controller is not installed, remain the address
data after installer sets central control address as he wants
2. In case that central controller is installed, there would be central
control address in wired remote control of indoor unit.
3. In this case, set the HR unit manual pipe address according to
central control address of indoor unit.
4. Pipe which is not connected with indoor unit should be set differ-
ent address with pipe Connected with indoor unit.
(If addresses are piled up, corresponding valve is not working.
5. If you want to change the setting of manual pipe, you should do
it on HR unit PCB.
6. If an error occurred, it means that manual pipe setting is not
completed.
7. During 5 minutes after pipe detection is completed, do not turn
off the main unit PCB to save the result of pipe detection auto-
matically.
The Procedure of Automatic Addressing

YES
Indoor address number is displayed on wired remote control or
indoor unit display window. It is not an error message, will
disappeared when on/off button is pressed on remote control
ex) Display of 01, 02, ..., 15 means connection of 15 indoor units
OK
and Automatic addressing is completed normally.
