7. OPERATION DESCRIPTION
FILE NO. SVM-03001
7-1.Outline of Air Conditioner Control
This is a fixed capacity type air conditioner, which uses
a AC motor for an indoor fan. The AC motor drive
circuit is mounted in the indoor unit. And electrical
parts which operate the compressor and the outdoor
fan motor, are mounted in the outdoor unit.
The air conditioner is mainly controlled by the indoor
unit controller. The controller operates the indoor fan
motor based upon commands transmitted by the
remote control and transfers the operation commands
to the outdoor unit controller.
The outdoor unit controller receives operation
commands from the indoor unit, and operates the
outdoor fan motor and the compressor.
(1) Role of indoor unit controller
7-1-1. Louver control
(1) Vertical air flow louver
Position of veritcal air flow louver is automatically
controlled according to the operation mode.
Besides, position of vertical air flow louver can be
arbitrarily set by pressing [FIX] button.
The louver position which is set by [FIX] button is
stored in the microcontroller, and the louver is
automatically set at the stored position for the next
operation.
(2) Swing
If [SWING] button is pressed when the indoor unit
is in operation, the vertical air flow louver starts
swinging. When [FIX] button is pressed, it stops
swinging.
The indoor unit controller receives the operation
commands from the remote control and executes
them.
• Temperature measurement at the air inlet of the
indoor heat exchanger by the indoor
temperature sensor
• Temperature setting of the indoor heat
exchanger by the heat exchanger sensor
• Louver motor control
• Indoor fan motor operation control
• LED display control
• Transferring of operation commands to the
outdoor unit
• Receiving of information of the operation status
and judging of the information or indication of
error
7-1-2. Indoor fan control (AC Fan motor)
(1) The indoor fan is operated by the stepless speed
change AC 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.
