 I FEEL mode

The unit selects the operation mode according to the room temperature 

when I FEEL is selected. When the room temperature is higher than 25°C, 

COOL is selected (set temperature: 24°C). When the room temperature is 

lower than 25°C, DRY is selected. However, when operation is stopped and 

then started within 2 hours, the mode which has been selected previously 

is operated.

Note: 

During COOL operation, the set temperature may not be changed when 

the room temperature is more than 2°C higher than the set temperature. 

In this case, please wait until the room temperature drops to within 2°C of 

the set temperature.
