The Procedure Of Automatic Addressing - LG ZRUM080LTS6 Installation Manual

The Procedure of Automatic Addressing

Power On
Waiting 3 minutes
Press RED Button for 5 s
(SW01C)
Automatic Addressing process start
7-segment LED = 88
Don't press RED Button
(SW01C)
• Automatic addressing process end Numbers of indoor
Waiting about 2~7 minutes unit connected are indicated for 30 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.
• Please be sure that all the DIP switch (except DIP switch 3) of
master outdoor unit is OFF before Automatic Addressing setting
- Set the DIP switch 3 to "on" if all the indoor units are
"ARN*******4".
- Set the DIP switch 3 to "oFF" if not all the indoor units are
"ARN*******4".
Setting For Heat Recovery Unit
(Refer Only Heat Recovery Installation)
Automatic pipe detection (For Heat Recovery System)
1
Turn No.1 DIP switch of SW02E of HR unit PCB off.
2
Confirm that the setting of No.2, 3, 4 of SW02E corresponds with
the type of the valve connection.
3
Reset the power of HR unit PCB
4
Master outdoor 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) : "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-SEG 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-SEG of
the outdoor unit main PCB for about 1 minute
- For a HR unit, the number of the indoor units connected to each
- '200' is displayed in case of auto pipe detecting error, and auto
!
• Execute auto addressing and auto pipe detection again whenever
the indoor PDB 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).
Check the connections
of communication cable
• 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 detectio
1
Enter the central control address into each indoor unit using its
wired remote controller.
2
Turn No.1 DIP switch of SW02E 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 of indoor units by using wired remote controller.
• 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.
• 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.
HR unit is displayed.
pipe detection process is completed when after "88" is
disappeared.
