1. INDOOR UNIT
1-1 Temperature Adjustment
(1) Cooling
When the room temperature is higher than the preset
temperature by 2˚Cor 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
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
difference
between the room and preset 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
the temperature goes below 21˚C during
operation.
Temperature of the indoor heat exchanger
35˚C
The indoor fan operates at low speed.

21˚C
The indoor fan stops.
1-3 Hot keep
If the room temperature is in the j or k zone during
heating, the compressor is turned on and off to
prevent overheating.
The fan goes off 30 seconds after the compressor
goes off.

1-4 Automatic operation
The operating mode and temperature setting are
determined by the room temperature and the external
air temperature.
The operating mode will changeover automatically
with the following condition.

1. From cooling to heating
Cooling mode will changeover to heating mode when
condition of indoor temperature 1.7˚C lower than the
set temperature conditions for 5 minutes.
2. From heating to cooling
Heating mode will change over to cooling mode when
condition of indoor temperature 1.3˚C higher than the
set temperature conditions for 25 minutes under Hot
keep condition.
3. When the set temperature is adjusted within the
range of ±2˚C by the remote control's key.
( ), the changeover judgement room temp. will
also be shifted within the range of ±2˚C.
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.

Fan
Same as Compressor
After "3 min. on - 3 min.off" is
repeated 4 times, the compressor
goes off, and only the fan
continues to repeat "3 min. on - 8
min.off".
