TIPS FOR SAVING ENERGY
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.

Installing ACP IV
CAUTION
Installing the ACP IV
yThe ACP IV installation work needs the professional technique. Therefore, the installation
described in this chapter should be performed by the certified installation professional.
yConsult the service center or the professional installation agency certified by us about any
question or request related to the installation.
Check points during the ACP IV installation
• The number of PI485 connected to one RS-485 communication line
ACP IV provides 4 RS-485 ports for indoor unit connection. (CH 1~4)
Up to 16 PI485 for outdoor unit can be connected to one RS-485 port, and up to 31 PI485 for
SINGLE/ERV can be connected.
• The number of the indoor units that can be connected to one ACP IV
One ACP IV can be connected up to 256 indoor units. With ACS I/O interlocking, you can
connect 128 indoor units and 16 I/O modules. And with chiller interlocking, you can connect
128 indoor units and 10 chiller units.
But, to improve the communication performance of RS-485, it is recommended to be divided
and connected to 4 ports.
To one RS-485 port, all of 256 indoor units, which is the maximum number that can be
connected to the ACP IV, may be connected.

• RS-485 communication cable connection
There is a polarity in RS-485 communication cable connection, so be careful not to reverse the
connection of the two cables.
Do not let the length of RS-485 communication cable exceed total of 1 Km.
RS-485 communication cable must be connected with BUS type.
• IP address of the ACP IV
IP address of the ACP IV, address of Gateway, and Net mask must be requested to the person
in charge of the network of the corresponding site.
CAUTION
RS-485 Connection of the ERV equipment
To connect ERV equipment, it is recommended to use the ports other than RS-485
communication ports which are connected to air conditioners.

ENGLISH
Installing ACP IV
Setting the indoor unit address
By considering the entire installation configuration connecting to one ACP IV, set the address to
each indoor unit not to be overlapped. 00~FF in hexadecimal can be set to the indoor unit address.
However, in case of I/O module, address 00 should not be set because address 00 is used as
Broadcast in MODBUS communication.
NOTES
Assigning indoor and outdoor unit number
If the outdoor unit product is Multi V, it is
recommended to assign the address by setting
the first digit of the address as the number of the
outdoor unit, and classifying the second digit as the
number or the indoor unit, for easy composition and
classification of the system.
Here is an example of configuring ACP IV and the device.
