(5) STOP (operation OFF) and ON-TIMER standby.
When the following cases occur, the horizontal vane returns to the closed position.
(a) When the 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 the VANE CONTROL button, the horizontal vane swings vertically. The remote controller
displays “
”.
(8) Cold air prevention in HEAT operation
When any of the following conditions occurs in HEAT operation, the vane angle changes to Angle 1
automatically to prevent cold air blowing on users.
①
Compressor is not operating.
➁
Defrosting is performed.
➂
Indoor coil thermistor RT12 reads 24
:
or below.
➃
Indoor coil thermistor RT12 temperature is raising from 24°C or below, but it does not exceed 28

(9) ECONO COOL (
) operation (ECONOmical operation)
When the ECONO COOL button is pressed in COOL mode, set temperature is automatically set 2°C higher than that in
COOL mode.
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 than that
in COOL mode, the air conditioner can keep comfort. As a result, energy can be saved.
ECONO COOL operation is cancelled when the ECONO COOL button is pressed once again or VANE CONTROL but-
ton is pressed or change to other operation mode.
NOTE : ECONO COOL operation not work in COOL mode of “I FEEL CONTROL”.
SWING operation
In swing operation of ECONO COOL operation air flow is initially blew out upward(levelly).
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 upward blow time is decided.
For initial 10 minutes the swing operation is performed in table G~H for quick cooling(but G : RT 12 is 24
:
or less).
Also, after 10 minutes when the difference of set temperature and room temperature is more than 2
:
, the swing oper-
ation is performed in table D~H for more cooling(but D: RT12 is 20
:
or less).
The air conditioner repeats the swing operation in various cycle as follows.
