Functions of ACP
1. ACP Functions & Specification
The ACP(Advanced Control Platform) is the central controller which can control up to 256 indoor units
of the airconditioner at one place individually or totally. The ACP can monitor or control to operate the
airconditioner and the ventilator installed at each room of the building from the place such as the
control room of a building, the administrative room of a school.
Main functions of the ACP are as follows:
Using the external button of the ACP to set the environment
The following functions can be set by using the external buttons of the ACP.
• Set the network environment (IP address, net mask, gateway)
• Set one of Peak/Demand function to use
• Set the language displayed on the LG ACCS screen
• Set whether to use the schedule feature or not
• Set whether to use the watthour meter feature or not.
Installation/Owner's Manual

1. ACP Functions & Specification
Built-in Web server
Various functions of contents can be used when the IP address of the ACP is entered at the address
window by using the Internet Explorer without installing a separate PC program to automatically
execute the central control program at the ACP web server.
Also, the demand control feature to control the demand power is controlled by directly connecting the
ACP to the demand controller without installing a separate PC program.
Interconnecting with the AC Manager
Various features offered by the AC Manager are offered by connecting the AC Manager program
installed at the PC to the ACP. Especially, when using the schedule feature of the AC Manager,
because the ACP has its own engine, even though the user turns off the PC where the AC Manager is
installed, the ACP can perform the schedule featre by itself.

2. Installing ACP
This chapter describes how to install the ACP to use.
In order to use the ACP, the environment for the ACP, the indoor unit and the ventilator to
communicate should be built and the indoor unit should be registered.
In order to use the ACP, the installation should be performed by the following order.
STEP 1. Check the environment before installing the ACP
Before installing the ACP, check the network configuration according to the
interconnection between the ACP and the external device.
STEP 2. Set the indoor unit address and Connecting the PI485
Set the address of the ACP not overlapped with the connecting indoor unit and connect
the PI485.
STEP 3. Install the ACP and set the environment and the function
Install the ACP and set the network environment and the function.
STEP 4. ACCS access and Information input
Set the access environment at the LG ACCS, the ACP operation program and enter the
air conditioner information.
STEP 5. Make sure and check the ACP installation
Make sure and check that the ACP is normally installed.
2. Installing ACP
Caution: Installing the ACP
The ACP installation work needs the professional technique. Therefore, the
installation described at this chapter should be performed by the certified
installation professional.
Consult the service center or the professional installation agency certified by us about
any question or request related to the installation.
ACP

2. Installing ACP
Before installing the ACP
ACP provides 4 RS485 ports to connect the indoor unit. Maximum of 16 units can be connected to
PI485 for outdoor unit in 1 RS385 port, and maximum of 31 units for SINGLE/Ventilator PI485.
256 indoor units at maximum can be connected to one ACP. All of 256 indoor units may be connected
to one RS485 port, which is the maximum number of units for the ACP to connect. But, in order to
improve the communication performce of the RS485, we recommend to distribute them to four ports.
By considering three following cases using the ACP, perform the installation after carefully considering
how to use.
• Install the single ACP to use as web server
• Connect the single ACP to the AC Manager to use
• Connect more than one ACP to the AC Manager via the hub to use
Note: Change the number of connections of RS485
If it is inevitable to change the above specification, call the system air conditioner support division

2. Installing ACP
Setting the indoor unit address
By considering the entire installation configuration connecting to one ACP, set the address to each
indoor unit not to be overlapped. 00~FF in hexadecimal can be set to the indoor unit address.
The next section describes how to set the address to each indoor unit by using the wired or wireless
remote controller according to the given number.
The following example sets the address to the indoor unit.
When the ACP is interconnected with the AC Manager, the ventilator can be together installed and
controlled. The above figure shows the example that sets 30 and 31 to the ventilators as address and
connects to the ACP.
Caution: Connecting the ventilator to the RS485
The ventilator and the air conditioner can not be connected together to the same
RS485 communication cable. When connecting the ventilator to the RS485
communication cable, the cable other than the RS485 communication cable
connecting the air conditioner should be used.

After setting the address of the indoor unit, install the PI485 and set the DIP switch. And then, connect
the RS485 cable for communicating with the ACP.
After installing the PI485 suitable to the product, the DIP switch should be set. The DIP switch of the
PI485 can be checked at the following place.

Tip: Checking the PI485 DIP switch setting
It can be checked whether the indoor unit address and the DIP switch of the PI485 are correctly set
as follows:
• The LED01G blinks as many as the number of the connected indoor units.
• The LED02G and the LED03G continue to blink alternately. (When the LRA/CRUN is
connected, the LED02G may blink more than the LED03G.)
If the LED is abnormally different from the above description, check again the indoor unit address
setting and the DIP switch setting.

2. Installing ACP
The following figure shows the example of the central control for connecting the 2PIN connector to the
CN_DRY terminal.
1) 'Heating operation, 20°C , Strong wind, Temperature lock' function is ordered by the central control
such as ACP or AC Manager, which is transferred to the remote controller.
2) If the user changes the temperature to 25°C by the remote controller, the related command is
transferred to the outdoor unit and the remote controller displays the 25°C setting.
3) The outdoor unit receives the related command and transferrs it to the PI485.
4)
The PI485 cancels this command and transferrs the previous central control command again. And, the
remote controller displays again the 20°C temperature transferred by the central control command.
On the other hand, let's see an example of connecting the 2PIN connector to CN_DRY terminal.
When a command is given for function of "Heat operation, 20°C setting, high fan level, temperature
lock" through the central control, the applicable command is transmitted through the remote
controller. "HL (Hard Lock)" message showing the central control status is displayed on the remote
controller. If the user sets the temperature to 25°C, the command is blocked at the remote controller.
