1 When the system is restarted with the remote controller, the system operates with the previous set temperature regard-
less of the 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 is controlled by TOO WARM or TOO COOL buttons when you feel too warm or too cool. 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
cold. 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.
…To raise the set temperature 1~2 (°C)
…To lower the set temperature 1~2 (°C)
(4) The initial set temperature is decided by the initial room temperature.

3. Coil frost prevention

Temperature control
When the indoor coil thermistor RT12 reads 1
:
(MCF-GA35VB)/ -1
:
(MCF-GA50/GA60VB) or below, the coil frost
prevention mode starts immediately. However the coil frost prevention doesn’t work for 5 minutes since the compressor
has started.
The indoor fan operates at the set speed the compressor stops for 5 minutes.
After that, if RT12 still reads below 1
:
(MCF-GA35VB)/ -1
:
(MCF-GA50/GA60VB) this mode is prolonged until
RT12 reads over 1
:
(MCF-GA35VB)/ -1
:
(MCF-GA50/GA60VB).
