Installation and Configuration

This chapter explains how to install and configure AC Smart BACnet.

Installation

To use AC Smart BACnet, build an environment for which AC Smart BACnet can communicate with devices like the indoor unit, ERV, DI/DO, DOKIT, AWHP, AHU and I/O Module. Use AC Smart BACnet to register those devices.

AC Smart BACnet should be installed in the following order:

STEP 1. Check the installation environment and configure the device address.

Check the network configuration against the interfaced devices before installing AC Smart BACnet and allocate a unique central control address for each connected device.

STEP 2. Connect BECON devices with AC Smart BACnet.

Use an RS485 cable to connect BECON devices with AC Smart BACnet.

STEP 3. Login and register the devices.

Login to AC Smart BACnet and register those devices that have their address set.

CAUTION

The installation of AC Smart BACnet must be done by a professional. Be sure to contact a qualified engineer for the installation. If you have a question or request regarding the installation, contact an installation professional at an authorized LG service center or LG Electronics.

PREPARATION 11

Check the installation environment and configure the device address

AC Smart BACnet can connect up to 128 devices (including indoor units, ERV, DI/DOs, DOKITs,

AWHPs, AHUs) or 64 devices (including indoor units, ERV, DI/DOs, DOKITs, AWHPs ans AHUs) and 9 I/O Modules.

BACnet protocol is not supported for Modular AHU and I/O module.

The following shows an example of connecting AC Smart BACnet with such devices.

AC Smart BACnet connects with PI485 and uses RS485 to communicate and exchange information. Allocate unique addresses to those devices (internal units, ERV, DI/DOs, DOKITs, AWHPs, AHUs, I/O Modules) that will connect with AC Smart BACnet. The addresses are hexadecimal numbers that can be chosen from 00 to FF.

NOTES

yy The maximum allowed communication distance guaranteed by LG Electronics is 1 000 m. It means that the distance between AC Smart BACnet and the farthest device should not exceed 1 000 m. It is recommended that the communication cable use 0.75 mm square or more.

yy For indoor units, ERV, DI/DOs, DOKITs, AWHPs, AHUs and I/O Modules, you cannot allocate identical addresses among devices of the same type. Allocate different addresses for devices of the same type. (the indoor unit and DOKIT cannot use the same address.)

yy Each device which can be used with PDI must be set to a unique address when connected with PDI. For further information about the devices can be used with PDI, please refer to the PDI manual.

yy Connecting I/O Module, address setting should not be 00 because 00 is used to Broadcast in MODBUS communication.

PREPARATION

AC Smart BACnet's RS485 connection

An AC Smart BACnet can have up to 128 indoor units. If there are many outdoor units to be connected, connect them to a bus. If not, AC Smart BACnet may malfunction.
