Product Instructions for Use

  1. Mounting: Install the ACP IV in a clean, dry control room or electrical cabinet. It can be DIN-rail mounted or fixed directly to a flat surface.

  2. Network Wiring: Connect the LG indoor units to the ACP via the PI-485 gateway. Use the LAN port to connect the ACP IV to the building’s local network (LAN) for remote access.

  3. Initial Setup: Access the configuration menu by entering the default IP address into a web browser. Set the system time, date, and assign unique addresses to each connected indoor unit.

  4. Energy Management: Utilize the energy-saving features to set setpoint limits and peak-wattage controls to prevent high electricity demand charges.

Q&A: Frequently Asked Questions

Q1: Do I need a special license for BACnet/IP connectivity? A1: Yes, while the hardware supports the protocol, a specific software license key is typically required to activate BACnet/IP communication for integration with third-party Building Management Systems (BMS).

Q2: Can I monitor the system from outside the local network? A2: Yes, by setting up port forwarding on your router or using a VPN, you can access the ACP IV web interface from any remote location with an internet connection.

Q3: What happens to the settings if there is a power failure? A3: The ACP IV features non-volatile memory and an internal battery backup for the clock, ensuring all schedules and configuration settings are retained during power outages.
