TIPS FOR SAVING ENERGY

ENGLISH

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 / dehumidif ying functions.

INSTALLING ACP LONWORKS

Check points during the ACP Lonworks installation

• The number of PI485 connected to one RS- 485 communication line ACP Lonworks provides 6 RS-485 ports. (CH 1~6)

- CH1~4 : ACP Lonworks provides 4 RS-485 ports for indoor unit connection.

Up to 64 indoor units (Up to 48 indoor units on PLNWKB100 version 2.2.0 or later)

- CH5 : ACP Lonworks provides 1 RS- 485 port for AHU unit connection. (Up to 16 AHU units)

- CH6 : No Use

Up to 16 PI485 for outdoor unit can be connected to one RS- 485 port, and up to 31 PI485 for SINGLE/ventilation can be connected.

• The number of the indoor units that can be connected to one ACP Lonworks One ACP can be connected Up to 64 indoor units (Up to 48 indoor units on PLNWKB100 version 2.2.0 or later)

To one RS-485 port, all of 64 indoor units (48 indoor units on PLNWKB100 version 2.2.0 or later), which is the maximum number that can be connected to the ACP Lonworks, may be connected.

But, to improve the communication performance of RS- 485, it is recommended to be divided and connected to 4 por ts.

• 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.

ENGLISH

• IP address of the ACP Lonworks

IP address of the ACP Lonworks, 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 ventilation equipment

To connect ventilation equipment, it is recommended to use the ports other than RS-485 communication ports which are connected to air conditioners.

INSTALLING ACP LONWORKS

Setting the indoor unit address

ENGLISH

By considering the entire installation configuration connecting to one ACP Lonworks, set the address to each indoor unit not to be overlapped.

Address range that can be set to indoor units are determined as selected module type.

• Module 0: 00~FF in hexadecimal can be set to the indoor unit address, but it can be connected Up to 64 indoor units (Up to 48 indoor units on PLNWKB100 version

2.2.0 or later)

• Module 1: 00~0F in hexadecimal can be set to the AHU unit address, and it can be connected up to 16 AHU units.

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.

Notes

How to set the central control address of the indoor unit

The central control address setting method may be different for each indoor unit product or remote control type, so set the address by referring to the manual of the indoor unit product or wired remote controller.

INSTALLING ACP LONWORKS

Setting the PI485 and connecting the cable

ENGLISH

After setting the address of the indoor unit, install the PI485 and set the DIP switch.

And then, connect the RS485 cable for communication with the ACP Lonworks.

Notes

Installing the PI485

Installing the PI485 depends on the outdoor unit.

So, install the PI485 by referring to the PI485 manual or the installation technique information.

To connect PI485 and the ACP Lonworks, two RS-485 cables need to be connected to BUS-A and BUS-B of PI485. Connect RS- 485 cable by referring to the following figure.
