(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(Tp
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 button is pressed
or LONG button is pressed or change to other operation mode.
NOTE : ECONO COOL operation not work in COOL mode of "I FEEL CONTROL".
SWING operation
w 1 Tp : Minimum value of indoor coil thermistor (main) RT12 and indoor coil thermistor (sub) RT13
In swing operation of ECONO COOL mode, the initial air flow direction is adjusted to "Horizontal".
According to the temperature of indoor coil thermistor Tp
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.

(10) LONG MODE ( )
By pressing the LONG button fan speed becomes faster than setting fan speed on the remote controller, and the hori-
zontal vane moves to the position for LONG mode. The remote controller displays "
when the LONG button is pressed once again or the VANE button is pressed or ECONO COOL button is pressed in
COOL mode .
