Indoor unit central control address setting
First, you need to grant address that does not overlap to each equip-
ment (indoor unit, ventilation equipment) considering the entire instal-
lation composition connected to one controller.
The address of the device must be set within the range of 00~0F.
Note : Granting outdoor unit and indoor unit number
If the outdoor unit product is Multi V, it is recommended to set the first
digit of the address as the outdoor unit number, and classify the sec-
ond digit as the indoor unit number, so that the system composition
and division can be easily identified during the address setting.

NOTE :
• The maximum allowable communication length guaranteed by LG
Electronics is 1000m. In other words, the controller and the farthest
installed device must be installed within the distance of 1000m.
• It is recommended to use the communication cable which is more
than 0.75 mm 2 .
• Set the address that does not overlap within the same device type.
• When multiple different wireless LAN equipment are connected to
the router to which you are connecting the controller, the wireless
LAN malfunction may be caused (Such as delayed operation
speed, disconnected, etc.) In this case, it is recommended to use a
separate router to connect the controller.
