TIPS FOR SAVING ENERGY
Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:
• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.

When a stopped indoor unit does not perform the central control command
• Some old model indoor units may not follow the central control command while it is not in operation.
• Therefore, you can order while it is in operation.
• For example, to change the set temperature and air direction of a stopped indoor unit, the set
temperature and air direction of the corresponding indoor unit may not be changed. In such case, if
you change the set temperature and air direction while the corresponding indoor unit is in operation, it
will be reflected properly to the indoor unit.
• With the same principle, for some indoor units, when the indoor unit in cooling operation with set air
direction is stopped, the air direction is stopped. And if the user starts the corresponding indoor unit
without setting air direction, the Auto Swing still remains at stopped state.

It is the function to perform the reserved operation at the specified time by specifying the operation of the air conditioner. For example, for the case of the school, the air conditioner automatically starts and stops at the specified time by setting the schedule to attending school and returning
home.
The unnecessary operation and management cost of the air conditioner can be reduced by this
schedule function, and it can effectively save the energy because it is used only when necessary.
Schedule can be set by logging in as super user or manager.
! CAUTION
Saving after the system setup
• When ‘group setting completed’ button is pressed in ‘system setting’ menu, all schedule
information currently set will be initialized, so be careful.
Time of ACP Lonworks
• When a user access ACP Lonworks through web browser, the time of PC and ACP
Lonworks are automatically synchronized, and ACP Lonworks executes schedule function
based on this time. Therefore, always maintain the time of PC to be the current time.

It maintains the consumed power to be kept lower than or equal to the target power by monitoring the power consumption of the air conditioner. Peak operation ratio control function can control with two methods according to the set peak operation rules to save energy.
The first is to stop or operate with wind only operation in turn to satisfy the peak operation ratio
set by the user, and the second is to adjust the cooling/heating performance of the outdoor unit
without stopping the indoor unit operation to satisfy the peak operation ratio.
Peak operation ratio control function has the following advantages:
- Centrally control all installed air conditioners by using the computer screen.
- Monitor and control the peak operation ratio for 24 hours a day.
- Easily perform controlling and monitoring.
- Set the peak control function operation ratio (%).
- Control the operation switching period (5~15 minutes) of the air conditioner.
- Set the peak group to give priorities of 5 stages for each group
(Priorities have 5 stages of very low, low, normal, high, and very high, and the very low is the
first controlled group.)

NOTE
When you connected the ACP Lonworks and PC through a cross cable, but you cannot
access the ACP Lonworks
• Check IP address of the ACP Lonworks and IP address of the PC.
Ex) If IP address of the ACP Lonworks is 192.168.1.101 and Net mask is 255.255.255.0,
check if the first three digits of the IP address of the PC is the same as the first three
digits of the IP address of the ACP Lonworks.
In such case, the IP address of the PC shall start with 192.168.1, and it shall be
different from the IP address of the ACP Lonworks. Set as follows, and try again.
- Setting of the ACP Lonworks
IP address: 192.168.1.112
Gateway address: 192.168.1.1
Subnet Mask: 255.255.255.0
- Setting of the PC
IP address: 192.168.1.113
Gateway address: 192.168.1.1
Subnet Mask: 255.255.255.0
• Check the status of the Ethernet cable (LAN cable).
!
NOTE
When PC and ACP Lonworks are connected together in a hub or a switch hub, and you
cannot access the ACP Lonworks.
• If it is right after changing the IP setting of the ACP Lonworks, reset the power of the ACP Lonworks.
• If it is right after connecting LAN cable to the hub or switch, it may take time for the hub or
the switch to recognize the ACP Lonworks. In such case, it may help to turn off and turn
on the power of the hub or the switch.
• Check the status of the Ethernet cable (LAN cable).
• Check ARP table of the PC to see if the IP address of the ACP Lonworks correctly
corresponds to the MAC address. If duplicate MAC addresses correspond to one IP
address, or if different address from the MAC address of the PC is output, there may be a
host with the same IP address as the IP address of the ACP Lonworks. In such case, the
IP address of the ACP Lonworks or the IP address of the corresponding host shall be
changed.

Troubleshooting
During the use of the ACP Lonworks, if unexpected problem occurs, please find the solution by
studying the following list.
When Tx or Rx LED of CH1~4 port is not blinking during the product installation
When Tx or Rx LED of CH1~4 port is not blinking during the product installation, run it after setting the indoor and outdoor unit groups.
When GUI cannot be operated in LG ACCS, which is the operation program of the ACP Lonworks
- When GUI cannot be operated in LG ACCS, which is the operation program of the ACP Lonworks, close Explorer window, and run new Explorer to access again.
- Close all iexplorer.exe process in Task Manager, and access to the ACP Lonworks again.
After running Task Manager, you can select
‘Task Manager’ in the popup menu window
displayed by clicking the right button of the
mouse on the menu bar of the window.
NOTES 123
When the ventilation equipment is displayed as a network error state (code 242) as followed, in
LG ACCS, which is the web server program of the ACP Lonworks, please check the following
categories.
- Check if the BUS-A and BUS-B of RS-485 cable are incorrectly connected.
- Check if there is a communication defect between the remote controller and the indoor unit.
- Check if the PI485 DIP switch is incorrectly set.
- Check if the indoor unit address for the central control is not set.
The CH242 (network error) keeps occurring and disappearing in the ACP Lonworks controller.
- Case of incorrect connection of RS-485 communication line
If each communication line is connected altogether as in the following figure, the communication
line must be separated.
PLNWKB000
)+84WV_WZS[
- Duplicate setting of the indoor unit address
It is the case of two or more indoor units are set with the same address. It may be the case of
several indoor units having the default address 00 by not setting the central control address from
the beginning for some indoor units.
In such case, assign unique address to each indoor unit not to have indoor unit with a duplicate
address.
ENGLISH
When the ventilation equipment is displayed as a network error state (code 242) in LG ACCS of the ACP Lonworks
124 NOTES
ENGLISH
It is installed by interfacing AC Ez and the ACP Lonworks, but some indoor units are not recognized,
or not properly performing the central control commands.
- It is the case of incorrect setting of AC Ez.
Set all AC Ez to Slave mode.
- If the indoor unit to control with AC Ez is in another physical line as in the following figure, the
AC Ez cannot recognize the corresponding indoor unit.
Therefore, the connections need to be modified to have the AC Ez to be in the same RS-485
communication line the indoor unit to control.

Wrong connection
When the image of LG ACCS is broken and you cannot see the screen such as the temperature well
- Close LG ACCS, and rerun.
※Cautions
- If PC is used for a long period of time, or several application programs are used at the same
time, PC performance may be degraded and may affect the ACP Lonworks UI.
- When you use LG ACCS, it is recommended to close other application programs.
- It is recommended to use LG ACCS only during the control and monitoring.
(Maximum of 3 hours of usage is recommended according to the PC environment.)
