Automatic pipe detection
1 Turn No.1 of DIP s/w SW02M of HR unit PCB off.
2 Confirm that the setting of No.2, 3 of SW02M corresponds with the
Type of the valve connection.
3 Reset the power of HR unit PCB
4 Master Out door unit PCB DIP switch on : No.5
5 Select the mode using ‘▶’, ‘◀’ Button : “Idu” Push the ‘●’ button
6 Select the “Id 5” function using ‘▶’, ‘◀’ Button :“Ath” or “”Atc”
Push the ‘●’ button.
Outdoor temperature is over 15°C(59°F) : “Atc” Using (If it fail, use
“Ath”)
Outdoor temperature is below 15°C(59°F) : “Ath” Using (If it fail,
use “Atc”)
7 Select the mode using ‘▶’, ‘◀’ Button : “Idu” Push the ‘●’ button
8 Select the “Id 6” function using ‘▶’, ‘◀’ Button :“StA” Push the
‘●’ button
9 System is operated after “88” is displayed on 7 segment of the
outdoor unit main PCB.
10 Pipe detection process is proceeded.
11 5~30 minutes are required depending on the number of the indoor
units and outdoor temperature.
12 The number of the indoor units connected is displayed on7
segment of the outdoor 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 detecting error, and auto
pipe detection process is completed after '88' is disappeared.
* Auto pipe detection function : the function that sets connection
relationship automatically between the indoor unit and HR unit.
WARNING
• Execute auto addressing and auto pipe detection again whenever the
indoor PCB and HR unit PCB is replaced.
- Operation error occurs unless power is supplied to the indoor and
HR units.
• Error No.200 occurs if the number of connected indoor units and that
of scanned indoor units are different.
• If auto pipe detection process fails, complete it with manual pipe
detection (see Manual pipe detection part).
• If auto pipe detection process is completed normally, manual pipe
detection is not required.
• If you want to do auto pipe detection again after auto pipe detection
fails, do after reset of outdoor unit by all means.
• During 5 minutes after pipe detection is completed, do not turn off
the main unit PCB to save the result of pipe detection automatically.
!
Manual pipe detection
1 Enter the central control address into each indoor unit using its
wired remote controller.
2 Turn No.1 of DIP s/w 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 outdoor 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 outdoor unit PCB, HR unit.
8 Manual pipe detection is completed
WARNING
• In case that central controller is not installed, firstly set up central
controller’s setting to make address setting of indoor units.
• In case that central controller is installed, please set central control
address in wired remote control of indoor unit.
• Do not set central control address of indoor unit to ‘0xFF’. (If the
address is ‘0xFF’, pipe detection will not be completed properly.)
• HR unit’s manual pipe address is set by the central control adress of
indoor units.
• Address of valve which is not connected with indoor unit should be
set differently with the address of a valve which is indoor unit
connected(If address is overlapped valve will not work preperly)
• If there occurs some error during pipe detection process,it means
pipe detection process is not properly finished.
• If an error occurred, it means that manual pipe setting is not
completed.
• During 5 minutes after pipe detection process is completed, do not
turn off the main outdoor unit’s PCB to save the result of pipe
detection automatically.

Master Outdoor unit’s PCB DIP switch on :
No.5
Completion of auto pipe detection process
* It is possible to be generated mode changing noise of
heating and cooling which is normal.
There is no mode changing noise at normal operation.
Is the number of
indoor units connected
and displayed
one equal?
Reset the power of HR unit PCB
Confirm that the setting of No.2, 3 of
SW02M corresponds with the valve
connecion type.
88' is displayed on7 segment
of the outdoor unit main PCB
Outdoor unit is operated for 5~60 minues.
The number of indoor units detected is
displayed for 30 seconds on the outdoor
unit PCB after outdoor unit stopped
Display error on outdoor unit PCB
Display error on HR unit PCB
Outdoor unit PCB : HR ơ HR unit
number ơ Valve number
HR unit : '200'
Check the HR unit and indoor unit
Pipe detection error occurs for 30
seconds.
Check the installation of status of
outdoor, indoor, HR unit
Incompletion of auto detection
process
Retry auto pipe detection process
after Fixing wrong installation
Dose the setting
status satisfy indoor unit’s
configuration properly
during operation?
Confirm indoor unit’s address setting
Turn No.1 of DIP s/w SW02M of HR unit
PCB off.
