For fan

Press the 3 [selecting operation] button and bring up the “FAN” display.

The fan operation functions to circulate the air in the room.

The temperature of the room cannot be set by fan operation.

For heating Caution:

Never expose your body directly to cool air for a long time. Excessive expo- sure to cool air is bad for your health, and should therefore be avoided.

Dry operation

The dry is a microcomputer-controlled dehumidifying operation which controls ex- cessive air-cooling according to the room temperature of your choice. (Not usable for heating.)

1.Until reaching room temperature of your choice

The compressor and indoor fan function is linked motion according to the change of the room temperature and automatically repeat ON/OFF.

2.When reaching room temperature of your choice Both the compressor and indoor fan stop.

When stop continues for 10 minutes, the compressor and indoor fan are oper- ated for 3 minutes to keep the humidity low.

For heating

Press the 3 [selecting operation] button to bring up the “HEAT” display.

Regarding displays during heating operation “DEFROST”

Displayed only during the defrosting operation.

“STAND BY”

Displayed from the start of heating operation until the moment warm air blows out.

3.3. Room temperature adjustment Caution:

When the air conditioner is used together with burners, thoroughly ven- tilate the area. Insufficient ventilation can result in accidents due to oxy- gen deficiency.

Never place a burner at a place where it is exposed to the airflow from the air conditioner.

Doing so can result in imperfect combustion of the burner.

The microcomputer functions in the following cases:

Air does not blow out when heating starts.

-To prevent any cool air from escaping, the indoor fan is gradually switched in sequence from faint airflow/weak airflow/set airflow according to the tem- perature rise of the blown out air. Wait a moment until the airflow comes out naturally.

The fan is not moving at the set speed.

-In some models, the system switches over to faint airflow when the tempera- ture of the room reaches the set temperature. In other cases, it stops to prevent any cool air from escaping during the defrosting operation.

Air flows out even if operation is stopped.

-Approximately 1 minute after the stop of operation, the indoor fan sometimes rotates to eliminate extra heat generated by the electric heater, etc. The fan speed comes to low or high.

3.3. Room temperature adjustment

To change room temperature

Press the 1 [room temperature adjustment] button and set the room tem- perature of your choice.

Pressing To change room temperature or 3.4. Fan speed adjustment once changes the setting by 1 °C [2 °F].

If the pressing is continued, the setting continues to change by 1 °C [2 °F].

Indoor temperature can be set within the following range.

Cooling/dry: 19 °C [67 °F] – 30 °C [87 °F]

Heating:

17 °C [63 °F] – 28 °C [83 °F]

It is impossible to set the room temperature by the air-blow operation.

*The range of room temperature display is 8 °C [46 °F] - 39 °C [102 °F]. Outside this range, the display flashes either 8 °C [46 °F] - 39 °C [102 °F] to inform you

if the room temperature is lower or higher than the displayed temperature.

3.4. Fan speed adjustment

To change fan speed

Every time you press the 6 [fan speed] button once, it switches from the low- speed to high-speed settings successively.

In the electronics dry operation, the indoor fan automatically turns to low-speed operation. Switching of fan speed is impossible. (Only the display on the remote controller changes.)

*Every time the fan speed adjustment button is once pressed, the fan speed is changed.

To change fan speed Caution:

Avoid putting your hand into the air outlet of the indoor unit any more than necessary during operation. If you get your hands caught in the metal parts when adjusting the airflow-direction-adjustment board and blowout grill, or nip them in the autovane, there is a risk of injury and failure.

3.6. Time setting

Set the current time after turning ON the power of the air conditioner or after restoration from a power failure.

It can be set regardless of the operation of the indoor unit.
