Installation and Configuration
ENGLISH
This chapter explains how to install and configure AC Smart Premium.
Installation
To use AC Smart Premium, build an environment for which AC Smar t Premium can communicate
with devices like the indoor unit, ERV, DI/DO, DOKIT, AWHP, and AHU. Use AC Smart Premium to
register those devices.
AC Smart Premium 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 Premium and allocate a unique central control address for each
connected device.
STEP 2. Connect V-Net devices with AC Smart Premium.
Use an RS485 cable to connect V-Net devices with AC Smart Premium.
STEP 3. Login and register the devices.
Login to AC Smart Premium and register those devices that have their address
set.
Caution
The installation of AC Smart Premium 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.
Check the installation environment and configure the device address

AC Smart Premium can connect up to 128 devices (including indoor units, ERV, DI/DOs, DOKITs,
AWHPs, AHUs).
The following shows an example of connecting AC Smart Premium with such devices.
AC Smart Premium 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) that will connect with AC Smart Premium. The addresses are hexadecimal numbers
that can be chosen from 00 to FF.

yThe maximum allowed communication distance guaranteed by LG Electronics is 1,000m.
It means that the distance between AC Smart Premium and the farthest device should not
exceed 1,000m. It is recommended that the communication cable use 0.75mm square or
more.
yFor indoor units, ERV, DI/DOs, DOKITs, AWHPs, and AHUs, 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.)
yEach 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.
