AUTO CHANGEOVER... AUTO MODE OPERATION

An automatic cooling and heating changeover operation system ensures easy control and year-round air conditioning.

Once the desired temperature is set, unit operation is switched automatically between cooling and heating according to the room temperature. In addition, fan control of the outdoor unit enables cooling operation at outside temperature as low as -10 °C.

To select the AUTO mode:

1 Press the	ON/OFF
	button.

2 Select the (AUTO) mode by pressing the MODE button.

Each time this button is pressed, the operation mode is changed in sequence:

(AUTO) → (COOL) → (DRY) → (HEAT)

The set temperature is also displayed on the remote controller.

To stop operation:

■ Press the	ON/OFF
	button.

After the operation mode is set once, the operation starts in the same mode as

ON/OFF

the one set previously from the next time by simply pressing the button.

■When the set temperature is to be changed:

TOO

WARM

•Press the button to lower the temperature. One press lowers the temperature by about 1°C.

TOO

COOL

• Press the button to raise the temperature. One press raises the temperature by about 1°C.

Description of “AUTO RESTART FUNCTION”

•These units are equipped with an auto restart function. When the main power is turned on, the air conditioner will start operation automatically in the same mode as the one set with the remote controller before the shutoff of the main power.

•If the unit was set to off with the remote controller before the shutoff of the main power, it will remain stopped even after the main power is turned on.

•If the unit is operated in “ AUTO” mode before power failure, the operation mode (COOL, DRY or HEAT) is not stored in the memory. When the main power is turned on, the unit decides the operation mode by the initial room

temperature at restart and starts operation again.

Information for multi system air conditioner

Multi system air conditioner can connect two or more indoor units with one outdoor unit. According to the capacity, two or more units can operate simultaneously.

•When you try to operate two or more indoor units with one outdoor unit simultaneously, one for the cooling and the other for heating, the operation mode of the indoor unit that operates earlier is selected. The other indoor units that will start the operation later cannot operate, indicating an operation state. (Refer to the table of Operation Indicator lamp below.)

In this case, please set all the indoor units to the same operation mode.

•When indoor unit starts the operation while the defrosting of outdoor unit is being done, it takes a few minutes (max. 10 minutes) to blow out the warm air.

•In the heating operation, the indoor unit that does not operate may get warm or the sound of refrigerant flowing may be heard. This is not a malfunction since the refrigerant continuously flows into the indoor unit that does not operate.

Details of display on the indoor unit

The operation indicator at the right side of the indoor unit indicates the operation state.

Description of “AUTO CHANGEOVER”

(1)Initial mode

1 When unit starts the operation with AUTO operation from off;

•If the room temperature is higher than the set temperature, operation starts in COOL mode.

•If the room temperature is equal to or lower than the set temperature, operation starts in HEAT mode.

(2)Mode change

1 COOL mode changes to HEAT mode when about 15 minutes have passed with the room temperature 2 degrees below the set temperature.

2 HEAT mode changes to COOL mode when about 15 minutes have passed with the room temperature 2 degrees above the set temperature.

NOTE:

If two or more indoor units are operating in multi system, there might be a case that the indoor unit, which is

operating in (AUTO), cannot change over to the other operating mode (COOL↔HEAT) and becomes a state of standby. Refer to the detailed information for multi system air conditioner explained on the right.
