7-1. FAN ONLY Operation

(MODE of the remote control : FAN ONLY)

(1)During this mode, the relay RY01 is always turned off so that only the indoor fan is operated. RY02 is always turnd on. FAN-ONLY display is lit.

1)When the FAN is set to AUTO, the indoor fan motor operates as shown in Fig 7-1-1.

2)When the FAN is set to LOW, MED, or HIGH, the indoor fan motor operates with a constant in volume as listed in Table 7-1-1.

(2)Once the setting is made, the operation mode is memorized in the microcomputer so that the same operation can be effected thereafter simply by

pushing the START/STOP button.

7-2. COOL Operation

(MODE of the remote control : COOL)

(2)Relays RY01 and RY02 are turned on to energize the outdoor unit, and a cool operation is carried out.

1)When the FAN is set to AUTO, the indoor fan motor operates as shown in Fig 7-2-2.

2)When the FAN is set to LOW, MED, or HIGH, the indoor fan motor operates with a constant in volume as listed in Table 7-1-1.

7-2-1. Louver Control

(1)By pushing the SET button of the remote control during the operation, the louver can be set to the desired position.

And the louver position is stored in the microcomputer, the louvers will be set to the position automatically at the next operation.

(2)When the AUTO button is pushed, the louver vertically swings within range of 25deg.

7-3. DRY Operation

(MODE of the remote control : DRY)

(1)Compressor, outdoor fan and operation display are controlled as shown in Fig. 7-3-1.

•The microprocessor turns the compressor on and off at regular intervals (4 to 6 minutes on and/or off). During the compressor off, the indoor fan will operate in the super low position.

•The indoor fan will operate in the AUTO position.

(2)The pattern of operation depending on the relation between room temperature and set temperature is shown below:

7-4. AUTO Operation

(MODE of the remote control : AUTO)

(1)One of the 2 modes, Cooling or Dry is selected according to room temperature at which operation is to start, as shown in Fig. 7-4-1. The Fan mode will continue until room temperature reaches a level at which another mode is selected.

7-4-1. Temporary Auto

When the TEMPORARY button is pushed, the set temperature is fixed at 24°C and controlled in accordance with the chart shown in Fig. 7-4-1.

7-5. ECONO. Mode

When the ECONO. button is pushed, during COOL and AUTO operation, the OPERATION display is turned off and the ECONO. display is lit and the indoor unit operates quietly and mildly with controlling airflow.

7-5-1. Cooling

(1)In the ECONO. mode, the set temp. by the remote control is changed automatically as shown in Fig. 7-5-1.

7-7. Auto Restart Function

7-7-1. How to Set the Auto Restart

This unit is equipped with an Automatic restarting facility which allows the unit to restart and resume the set operating conditions in the event of a power supply shutdown without the use of the hand control.

The operation will resume without warning three minutes after the power is restored.

The Auto Restart function is set not to work on shipment from the factory, and so it is necessary to set it to function as required.

• When the system is stand-by (not running)

To set the Auto Restart function, proceed as follows: Access the TEMPORARY button located in the lower right hand corner beneath the hinged front panel of the indoor unit (please refer to section on PARTS NAME). The power supply to the unit must be on - the function will not be set if the power is off.

To enable the Auto Restart function, press the TEMPORARY button continuously for three seconds. The unit will acknowledge the setting and beep three times. The system will now restart automatically.

The above Auto Restart settings can be carried out:

7-7-3. In Case of Power Failure during the Timer Operation

(1)If ON-TIMER operation is reserved with setting of Auto Restart operation, it is cancelled with power failure. (The OPERATION lamp on the main unit goes on and off to inform of power failure.) In that case, try to reserve ON-TIMER operation once again.

(2)If OFF-TIMER operation is reserved without setting of Auto Restart operation, the reservation is cancelled with power failure. (The OPERATION lamp on the main unit goes on and off to inform of power failure.) In that case, try to reserve OFFTIMER operation. When Auto Restart operation is set, OFF-TIMER reservation is also cancelled with power failure.
