(8) 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(Tp

(w 1)).

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(MS-18/24RV)/ VANE button(MS-30RV) is pressed or LONG button(MS-30RV only) is pressed or change to other

operation mode.

NOTE : ECONO COOL operation does not work in COOL mode of “I FEEL CONTROL”.

SWING operation

w 1 Tp :•Value of RT12(MS-18/24RV)

•Minimum value of indoor coil thermistor (main) RT12 and indoor coil thermistor (sub) RT13 (MS-30RV)

In swing operation of ECONO COOL operation air flow is initially blew out upward(levelly).

According to the temperature of indoor coil thermistor Tp

(w 1) 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 : Tp

(w 1) is 24: or less).

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(but D: Tp

(w 1) is 20: or less).

The air conditioner repeats the swing operation in various cycle as follows.

Temperature of Tp(w 1)

more than 24°C

Downward blow time

(sec.)

22°C to 24°C

21°C to 22°C

20°C to 21°C

18°C to 20°C

17°C to 18°C

15°C to 17°C

15°C or less

horizontal vane moves to the position for LONG mode. The remote controller displays “ ”. LONG mode is cancelled

when the LONG button is pressed once again or the VANE button is pressed or in COOL mode ECONO COOL button is

pressed.

• In the following example, the vertical vane is set to (front.).
