7. OPERATION DESCRIPTION
7-1. Outline of Air Conditioner Control |
7-1-1. Louver control |
This is a fixed capacity type air conditioner, which uses AC motor for an indoor fan. The AC motor drive
circuit is mounted in the indoor unit. And electrical parts which driving the compressor and the outdoor fan motor, are mounted in the outdoor unit.
The air conditioner is controlled by the controller mounted in the indoor unit. The controller operates all components based on the commands transmitted from the remote control and the feedback data of the sensor is as follow:
∙The temperature measurement at the air inlet of the indoor heat exchanger by the indoor temperature sensor
∙ The temperature measurement at the indoor heat exchanger by the indoor heat exchanger temperature sensor
∙Indoor fan motor operation control
∙Louver motor control
∙LED display control
∙Outdoor fan motor operation control
∙4-WAYS-VALVE operation control
(Heat pump model only)
∙Compressor operation control
∙Receiving the information of the operation status and judging the information or the indication of errors
(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 [SWING] button is pressed again, it stops swinging.
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.
LOW+ = LOW+MED 2
MED+ = MED+HIGH 2

7-2. Description of Operation Circuit
(1)When turning on the breaker, the operation lamp blinks. This means that the power supply is on.
(2) When pressing [ ] button on the remote control, receiving beep sounds from the indoor unit, and the next operation is performed together with opening the vertical air flow louver.
(3)Once the operation mode is set, it is memorized in the microcontroller so that the previous operation can be effected thereafter simply by pressing
[ |
] button. |
7-2-1. Fan only operation
([MODE] button on the remote control is set to the fan only operation.)
(1)When [FAN] button is set to AUTO, the indoor fan motor operates as shown in Fig. 7-2-1. When [FAN] button is set to LOW, LOW+, MED, MED+ or HIGH, the motor operates with a constant air flow.

7-2-2. Cooling operation
([MODE] button on the remote control is set to the cooling operation.)
(1)The compressor, 4-way valve, outdoor fan and operation display on the remote control are controlled as shown in Fig. 7-2-2.

(1)One of 3 operations (Cooling, Fan only or Heating) is selected according to difference between the preset temperature and the room temperature at which the automatic operation has started, as shown in Fig. 7-2-9. The Fan only operation continues until the room temperature reaches a level at which another mode is selected.
(2)Temporary Auto
When the [RESET] button on the indoor unit
is pushed, the preset temperature is fixed at 24 °C and the indoor unit is controlled as shown in
