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 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.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or reduce the cooling / dehumidifying functions.

Power heating

Description

Cool the room to the desired temperature.

It removes the moisture with cooling.

Heats the room to the desired room temperature.

The product automatically provides the appropriate fan speed based on the temperature of the room.

Fan only operation, no cooling or heating.

It provides strong cooling in short time.

Power heating increases indoor temperature quickly.

What is 3 minute delay function?

After the cooling stops, when the product is started right away, the reason that the cold wind does not come out is that it is the function to protect the compressor.

The compressor starts after 3 minutes and the cold wind comes out.

!

NOTE

The compressor starts after 3 minutes and the cold wind comes out.

In the cooling operation, you can select the desired temperature in the range of 18°C ~ 30°C

(16°C ~ 30°C).

The favorable temperature difference between the indoor temperature and the outdoor temperature is 5°C.

For some types of the indoor units, you can select the desired temperature in the range of

16°C ~ 30°C.

20


Heating Operation

The heating operation’s minimum setting temperature is 16°C.

For some types of the indoor units, the desired temperature can be controlled in the units of 1°C or 0.5°C.

- Set the desired temperature higher than the indoor temperature.

- Indoor temperature is displayed on the default screen of the remote controller.

- When the desired temperature is set lower than the indoor temperature, warm air doesn't come out, but for some products, the fan will recirculate room air, or stop altogether.

- If you unit is operating in heating mode and you press the [On/Off] button the heatling operation will shut off.


21

Dry Operation

Dry operation’s initial fan speed is “Low”.

Dry operation does not have a separate desired temperature.

- If you unit is operating in dehumidification mode and you press the [On/Off] button the dehumidification operation will shut off.

!

NOTE

If you use it in the rainy season, or when the humidity is high, you can have both the effective dehumidification and cooling operation at the same time.

!

NOTE

In the heating operation, you can select the desired temperature in the range of 16°C ~ 30°C.

Heating operation is operated only in cooling/heating model. The heating is not operated in cooling exclusive model.

22


Fan Only Operation

Fan only operation’s initial wind strength is “High”.

Fan only operation does not have a separate desired temperature.

- If you unit is operating in fan only mode and you press the [On/Off] button the the unit will stop.


23

AI / Auto operation

Auto operation’s initial desired temperature is 25°C.

The cooling exclusive model’s initial desired temperature is “It’s Fine”.

Cooling/heating model’s desired temperature can be controlled in the units of 1°C or 0.5°C.

For cooling exclusive model, the value can be controlled from “hot” stage to “cold” stage.

- Hot

- A little hot

- It’s fine

- A little cold

- Cold

- If you unit is operating in ai/auto mode and you press the [On/Off] button the ai/auto operation will shut off.

!

NOTE

It provides the Fan only operation without temperature control, with recirculation of indoor air.

!

NOTE

If the product is a cooling/heating model, in the auto operation, the desired temperature can be selected in the range of 18°C ~ 30°C.

If it does not operate as you wish, select another operation mode.

24


Dual setpoint auto operation

The indoor unit automatically manages room temperature with extended heating and cooling setting temperature ranges.

Dual setpoint auto mode can be set in the USER SETTING. This is recommended in North America region.


25

Power Cool Operation

Power cooling quickly lowers the indoor temperature.

Desired temperature: 18°C

Fan speed : Power fan speed

Fan direction: Current fan direction

- During the power cooling, if fan speed or desired temperature is changed, the power cooling is cleared, and it operates in the cooling operation mode.

- During the power cooling, if you press [On/Off] button, the power cooling operation stops, and when you press [On/Off] button again, it operates in the cooling operation mode.

!

NOTE

• Auto heating function only operates on cooling and heating models.

• Auto heating function doesn’t operate on cooling only models.

GUIDE TO DIFFERENT MODE

OPERATION/OPEN SOURCE SOFTWARE

Different mode operation

Different mode operation is the case when the indoor units’ operation modes are different when multiple indoor units are installed to one outdoor unit. (Different mode operation doesn’t happen in the cooling exclusive model.)

• Example of different mode operation

- When one indoor unit is operated in heat while several indoor units one outdoor unit are operated in cooling, the heating operation is not performed.
