8-6. i-see CONTROL OPERATION

The sensors constantly measure the room and floor/wall temperatures to automatically adjust to the set temperature by esti- mating the temperature actually perceived by a person inside the room (“sensory temperature”).

Advantages

·The air inside the room is conditioned quickly to a comfortable condition.

·The room will not become too cold or hot even when the air conditioner is kept on for a long period.

·The air conditioner will not overcool or overheat, which means you can save on electricity.

i-see control operation is activated when i-see button is pressed with a thin stick in manual COOL or manual HEAT mode. NOTE : i-see control operation is activated when the remote controller is first used following replacement of the batteries

or resetting of the remote controller.

i-see control operation is cancelled when i-see button is pressed with a thin stick once again.

NOTE : If the conditioner is turned OFF without cancelling i-see control operation, i-see control operation is activated the next time the air conditioner is turned ON.

i-see Sensor

i-see Sensor, which is installed on the upper of the air outlet of the indoor unit, is moved with the stepping motor and it detects the floor/wall temperature.

i-see Sensor is installed here.

•Install the front panel correctly after being removed for maintenance or service so that the floor/wall temperatures can be measured correctly.

8-7. AREA ( ) SETTING

(1)Press OPERATE/STOP (ON/OFF) button to start the air conditioner.

(2)Press i-see button. (NOTE1)

(3)Press AREA button.

Each time the button is pressed, the area is changed in sequence:

(AUTO) (LEFT) (RIGHT) Cancel

i-see Sensor moves intermittently, measuring the floor and wall temperature.

(4)AREA setting is cancelled when the "cancel" is selected by pressing AREA button, or when WIDE VANE button is pressed.

NOTE1 : AREA setting is only available during i-see control operation.

NOTE2 : If AREA setting is cancelled, the vertical vane returns to the previously set position before AREA setting.

NOTE3 : The horizontal air flow direction (WIDE VANE button), including horizontal SWING, cannot be set during AREA setting
