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. P.M.V. (Pulse Modulating Valve)
Using P.M.V., refrigerant flow of refrigeration cycle is
varied for the optimum temperature.
After the power has been turned on, when a serial
operation signal is received from indoor at the first
time, or when PMV alarm is detected and the equip-
ment is reactivated, move the valve once until it hits on
the stopper for positioning of the valve. In this case,
ticktack sound may be heard.
8-1-6. Louver control
(1) Vertical air flow louvers
Positions of vertical air flow louvers are
automatically controlled according to the operation
status (AUTO (A), COOL ( ), DRY (
), HEAT( )
and FAN ONLY (
). Besides, positions of vertical
(2) Swing
If the [SWING] button is pressed during running
operation, vertical air flow louvers start swinging.
When the [
SWING] button is pushed, swinging stops.
8-1.7. Indoor fan control
(1) The indoor fan is operated by the stepless speed
change
motor.
(2) For air flow level, speed of the indoor fan motor is
controlled in five steps (LOW, LOW
+
, MED, MED
+
and HIGH). If AUTO mode is selected, the fan
motor speed is automatically controlled by the
difference between the preset temperature and
the room temperature.
