(3) Positioning
The vane is once pressed to the vane stopper below to confirm the standard position and then set to the desired angle.
Confirming of standard position is performed in case of follows.
(a) When OPERATE / STOP(ON/OFF) button is pressed. (POWER ON/OFF)
(b) When the vane control is changed from AUTO to MANUAL.
(c) When SWING is finished.
(d) When the test run starts.
(e) When the power supply turns ON.
(4) VANE AUTO (
) mode
In VANE AUTO mode, the microprocessor automatically determines the vane angle to make the optimum room-temper-
ature distribution.
1
In COOL and DRY operation
2
In FAN operation
Vane angle is fixed to Angle 1.
Vane angle is fixed to Angle 4.
(5) STOP (operation OFF) and ON-TIMER standby.
When the following cases occur, the horizontal vane returns to the closed position.
(a) When OPERATE/STOP(ON/OFF) button is pressed (POWER OFF).
(b) When the operation is stopped by the emergency operation.
(c) When the ON-TIMER is on standby.
(6) Dew prevention
During COOL or DRY operation at Vane Angle 4 or 5 when the cumulative operation time of compressor exceeds 1
hour, the vane angle automatically changes to Angle 1 for dew prevention.
(7) SWING MODE (
)
By selecting SWING mode with VANE CONTROL button the horizontal vane swings vertically. The remote controller
displays “
”.
(8) ECONO COOL (
) operation
When the ECONO COOL button is pressed in COOL mode, set temperature is automatically set 2
:
higher than that in
COOL mode.
Also the horizontal vane swings in a cycle which fits the temperature of indoor heat exchanger(RT12).
SWING operation makes you feel cooler than set temperature. So, even though the set temperature is higher than that in
COOL mode, the air conditioner 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
When the vane swings in ECONO COOL operation, air blows initially in a horizontal direction.
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
:
, 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.
