8-1-4. Prevent-freezing control
The indoor heat exchanger sensor detects refrigerant
vapor temperature in COOL/DRY operation. If the
temperature is below the specified value, compressor
motor speed is reduced so that operation is performed
in temperature below the specified value to prevent-
freezing of indoor heat exchanger.
8-1-5. Louver control
(1) Vertical air flow louvers
Positions of vertical air flow louvers are automati-
cally controlled according to the operation status
(AUTO (A), COOL ( ), DRY ( ), HEAT( ) and
FAN ONLY ( ). Besides, positions of vertical air
flow louvers can be arbitrarily set by pressing the
[FIX] button.
(2) Swing
If the [SWING] button is pressed during running
operation, vertical air flow louvers start swinging.
When the [FIX] button is pressed, swinging stops.

8-1-6. Indoor fan control (DC fan motor)
(1) The indoor fan is operated by the stepless speed
change DC motor.
(2) For air flow level, speed of the indoor fan motor is
controlled in five steps (LOW, LOW
and HIGH) as described in Table 8-1-2. If AUTO
mode is selected, the fan motor speed is automati-
cally controlled by the difference between the
preset temperature and the room temperature.
