Older versions (v2.0 to v3.5) were hosted on LG’s public server:

For smart buildings, the ACP acts as a translator. The configuration tools allow you to map specific HVAC data points (such as room temperature, error codes, and fan speeds) to BACnet objects or Modbus registers. This ensures your third-party BMS (like Honeywell, Johnson Controls, or Schneider Electric) can seamlessly read and write data to the LG system. 3. Firmware Flashing and Backups

System configurations—including customized unit names, zone groupings, interlocking logic, and operational schedules—can take days to set up manually. The tool allows you to export a complete backup of these settings. If a controller suffers hardware failure, the configuration can be restored to a replacement unit in minutes. Diagnostic Logs and Troubleshooting

Set your laptop's Ethernet properties to a static IP address in the same range as the controller (e.g., if the controller is 192.168.1.100 , set your laptop to 192.168.1.101 Launch the Tool : Open the application and enter the actual IP address of the LG controller.
