The Procedure of Automatic Addressing
Power On
Waiting 3 minutes
Press RED Button for
5 seconds (SW01C)
Automatic addressing process start
7-segment LED = 88
Don't press RED Button
(SW01C)
• Automatic addressing process end
Numbers of indoor unit connected are indicated for 30
Waiting about 2~7 minutes
seconds on 7-segment LED after completing process.
NO
7-segment LED
= 88
YES
Indoor address number is displayed on wired remote controller or
indoor unit display window. It is not an error message, will
disappeared when on/off button is pressed on remote controller
ex) Display of 01, 02, ..., 15 means connection of 15 indoor units
OK and Automatic addressing is completed normally.
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 has to be performed after more than 3
minutes to improve indoor unit communition when initial power is
supplied.
Setting For Heat Recovery Unit (Refer Only Heat Recovery Installation)
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 :"Atc" or "Ath"
Push the '●' button.
Outdoor temperature is over 15 °C(59 °F) : "Ath" Using (If it fail,
use "Atc")
Outdoor temperature is below 15 °C(59 °F) : "Atc" Using (If it fail,
use "Ath")
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 on 7
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.
!
• 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
• 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.
Check the connections
of communication cable
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
!
• 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 units's manual pipe address is set by the central control
address 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
properly)
• 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.
