Example
Previous operation
COOL mode of
“I FEEL CONTROL”
or COOL mode
• Once the mode is fixed, the mode does not change by room temperature afterwards.
• Under ON-TIMER ( ) operation, mode is determined as follows.
When the system is stopped on the remote controller, and restarted within 2 hours in “I FEEL CONTROL” ( ) mode,
the system operates in previous mode automatically regardless of the room temperature.
Example
Previous operation
COOL mode of
“I FEEL CONTROL”
or COOL mode
When the system is restarted after 2 hours and more, the operation mode is determined by the room temperature at
start-up of the operation.

1 When the system is restarted with the remote controller, the system operates with the previous set temperature regard-
less of room temperature at restart.
The set temperature is calculated by the previous set temperature.
(5) TEMPERATURE buttons
In “I FEEL CONTROL” ( ) mode, set temperature is decided by the microprocessor based on the room temperature.
In addition, set temperature can be controlled by TOO WARM or TOO COOL buttons when you feel too cool or too warm.
Each time TOO WARM or TOO COOL button is pressed, the indoor unit receives the signal and emits a beep tone.
•
Fuzzy control
When TOO COOL or TOO WARM button is pressed, the microprocessor changes the set temperature, considering the
room temperature, the frequency of pressing TOO COOL or TOO WARM button and the user’s preference to heat or
cool. So this is called “Fuzzy control”, and works only in “I FEEL CONTROL” mode.
In DRY mode of “I FEEL CONTROL”, the set temperature doesn’t change.
