Hardware Installation - LG BNU-BAC Owner's Manual

Hardware Installation

(1) Setting the indoor unit address
• By considering the entire installation configuration connecting to one BACnet Gateway, set the
unique address for each indoor unit. (We recommend to reflect it to the installation drawing.)
• Two hexadecimal digits 00~FF can be set to the address of the indoor unit.
• For the Multi V product, in order to identify the system component, we recommend to set the outdoor
unit number to the first digit of the address and the indoor unit number to the second digit.
• The ventilating product can be also installed and controlled by the BACnet Gateway.
(However, the address of the ventilation product cannot be set to overlap the address of the air
conditioner.)
