Fan speed adjustment, Ventilation, Others

For fan

Press the 3 [Mode (Back)] 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.

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 [Mode (Back)] Button to bring up the “HEAT” display.

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 pressed once, the fan speed is changed.

(AUTO*)

*This setting can be adjusted only with MA remote controller.

3.5. Ventilation

•The ventilation unit (OA processing unit or LOSSNAY) automatically goes into operation when the indoor unit that is interlocked with it goes into operation.

•If the 8 [Ventilation] button is pressed while the indoor unit is stopped, only the ventilator goes into operation.

•Press the 8 [Ventilation] button to change the fan speed.

•Depending on the models, the indoor unit fan goes into operation while the unit is in the ventilation mode.

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

Caution:

•When the air-conditioner is used together with burners, thoroughly venti- late 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 tempera- ture 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 temper- ature 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 some- times 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 [Set Temperature] Button and set the room temperature of your

choice.
Pressing	or	once changes the setting by 1 °C/1 °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]

•Temperature cannot be set for the fan mode.

*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.
