Horizontal vane ECONO COOL ( ) operation (ECONOmical operation) When ECONO COOL button is pressed in COOL mode, set temperature is automatically set 3.6 degrees 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,

However, it's necessary to locate the polar direction of rotor in order to drive brushless DC motor efficiently. The general detection method of the polar direction for such a DC motor is to locate it from the voltage induced by unenergized stator. Therefore, It is necessary to have a cert
