(2) 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 (Tp
( 1)
).
SWING operation makes you feel cooler than set temperature. So, even though the set temperature is higher, the air
conditioner can keep comfort. As a result, energy can be saved.
ECONO COOL operation is cancelled when ECONO COOL button, VANE CONTROL button, VANE button or LONG but-
ton is pressed or changed to other operation mode.
NOTE:
ECONO COOL operation does not work in COOL mode of “I FEEL CONTROL”.

1 Tp: • Value of indoor coil thermistor
(MSC-GE20/25/35VB, MS-GE50VB, MSH-GE50VB)
• Average value of indoor coil thermistor (main) and indoor coil thermistor (sub)
(MS-GD80VB, MSH-GD80VB)
In swing operation of ECONO COOL operation mode, the initial airflow direction is adjusted to “Horizontal”.
According to the temperature of indoor coil thermistor Tp
( 1)
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 between set temperature and room temperature is more than 2°C, the swing
operation is performed in table D ~ H for more cooling.
The air conditioner repeats the swing operation in various cycle as follows.
