(1) Control for indoor freezing prevention
If the temperature of the indoor heat exchanger stays
below approximately 0
°
C for four minutes during
cooling or dry, this control stops the compressor. Over
2˚C the compressor will run again.
(2) Control for cold air blowing prevention
When heating begins, this control stops the indoor fan
until the temperature of the indoor heat exchanger
reaches 26
°
C. It also stops the fan if the temperature
goes below 23
°
C during operation.
(3) Indoor fan and operating frequency
The indoor fan has 12 speeds, and changing is done
in four stages, "Auto", "High", "Med", and "Low". The
relations between the indoor fan speed, air quantity
setting, operating frequency, and indoor heat
exchanger are shown in the following charts.
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 fuzzy
computing one hour before the set time.
