FUNCTIONS
1. INDOOR UNIT
1-1 Temperature Adjustment
1-1 Temperature Adjustment
(1) Cooling
When the room temperature is higher than the preset
temperature by 2˚C or more, the unit runs at the
maximum operation frequency until the temperature
comes down to the preset temperature.
When reaching the preset temperature, the unit runs
at the frequency calculated by the fuzzy operation
and switches to the normal control.
temperature by 2˚C or more, the unit runs at the
maximum operation frequency until the temperature
comes down to the preset temperature.
When reaching the preset temperature, the unit runs
at the frequency calculated by the fuzzy operation
and switches to the normal control.
(2) Heating
When the room temperature is lower than the preset
temperature by 3.5˚C or more, the unit runs at the
maximum operation frequency until the temperature
comes down to the preset temperature.
When reaching the preset temperature, the unit runs
at the frequency calculated by the fuzzy operation

When reaching the preset temperature, the unit runs
at the frequency calculated by the fuzzy operation
and switches to the normal control.
(3) Dry
After operation begins, 2 minutes of the room
temperature is stored in memory, and that becomes
the set value.

1-2 Indoor fan control
(1) Cooling
The fan speed can be selected from "Auto",
"Soft", "Low",and "HIgh".When "Soft", "Low" or
"HIgh" is selected, the fanspeed is constant
regardless of the room temperature.When "Auto"
is selected, the fan speed automatically changes
between "Soft" and "HIgh" depending on the
d i f f e r e n c e b e t w e e n t h e r o o m a n d p r e s e t
temperature.
Control for indoor freezing prevention
If the temperature of the indoor heat exchanger
stays below approximately 1˚C for four minutes
during cooling or dry, this control stops the
compressor. Over 3˚C the compressor will run
again.

(2) Heating
Control for cold air blowing prevention
When heating begins, this control stops the
indoor fan until the temperature of the indoor heat
exchanger reaches 23˚C. It also stops the fan if
t h e t e m p e r a t u r e g o e s b e l o w 2 1 ˚ C d u r i n g

1-3 Hot keep
If the room temperature is enough high during heating,
the compressor is turned on and off to prevent
overheating.

1-5 ON-timer
The ON-timer is set by pressing the ON-timer button.
In order to attain the set temperature at the set time,
the operation starting time is corrected by neuro and
fuzzy computing one hour before the set time.
