(4) VANE AUTO (
) mode
The microprocessor automatically determines the vane angle and operation to make the optimum room temperature distri-
bution.
COOL and DRY operation
Vane angle is fixed to Angle 1.

(5) STOP and ON-TIMER standby
When the following cases occur, the vane returns to the closed position.
(a) When the operation is stopped by the remote controller.
(b) When the operation is stopped by the emergency operation.
(c) When ON-timer is on standby.
(6) Dew prevention
During COOL or DRY operation at position 4 or 5 when the compressor cumulative operation time exceeds 1 hour, the
angle of horizontal vane automatically changes to position 1 for dew prevention.
(7) SWING MODE(
)
By selecting SWING mode with VANE CONTROL button, the horizontal vane swings vertically. The remote controller dis-
plays "
".SWING mode is cancelled when VANE CONTROL button is pressed once again.
(8) ECONO COOL (
) operation (ECONOmical operation)
When ECONO COOL button is pressed in COOL mode, set temperature is automatically set 2°C higher.
Also the horizontal vane swings in various cycle according to the temperature of indoor heat exchanger(RT12).
SWING operation makes you feel cooler than set temperature. So, even though the set temperature is higher, the air con-
ditioner can keep comfort. As a result, energy can be saved.
ECONO COOL operation is cancelled when ECONO COOL button is pressed once again or VANE CONTROL
button is pressed or change to other operation mode.
NOTE : ECONO COOL operation does not work in COOL mode of "I FEEL CONTROL".
<SWING operation>
In swing operation of ECONO COOL operation mode, the initial air flow direction is adjusted to "Horizontal".
According to the temperature of indoor coil thermistor RT12 at starting of this operation, next downward blow time is
decided. Then when the downward blow has been finished, next horizontal blow time is decided.
For initial 10 minutes the swing operation is performed in table G~H for quick cooling.
Also, after 10 minutes when the difference of set temperature and room temperature is more than 2 °C, the swing opera-
tion is performed in table D~H for more cooling.
The air conditioner repeats the swing operation in various cycle as follows.
