8 Operation Details
8.1.Basic Function
Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air temperature.
8.1.1.Internal Setting Temperature
Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes. These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit.

High voltage PWM Motor
2.Feedback Control
a.Number-of-rotations feedback
Immediately after the fan started, rpm is checked and duty is added, and feedback control is performed. For high voltage PWM motor, it is done once every 0.5 second.
b.Offset duty T max/min limit
High voltage PWM motor has maximum offset duty. (Refer Indoor fan motor control basic rotation speed)
3.Abnormal Detection Control Conditions:
a.Out of rhythm signal input
b.If feedback number of rotations exceeded #2550 r/min or when less than #50 r/min.
Control: Fans stop
Return: Restart after 5 seconds
* It will not detect the out of rhythm condition within 5s for phase control motor (PWM motor is when duty=0) after start.
A fan stops when condition (1) and (2) happen within 25.0 seconds after fan starting, and if this happens for continuously 7 times, it will not retry.
→ FM lock processing
4.Restart Prohibition Control
Restart is prohibited within 5s for phase control motor (PWM motor is when duty=0) after fan stop (except re-ON the power supply).

Outdoor fan motor is operated with one fan speed only. It starts when compressor starts operation and it stops 30 seconds after compressor stops operation.
8.1.9.Airflow Direction
1.There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by vertical vanes).
2.Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat exchanger temperature and intake air temperature) and manual (angles of direction can be adjusted using remote control).

1.Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the angles as stated above. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1 below. When the air conditioner is stopped using remote control, the vane will shift to close position.
2.Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated above and the positions of the vane are as Figure 2 below. When the air conditioner is stopped using remote control, the vane will shift to close position.
8.1.9.2.Horizontal Airflow
1.Automatic horizontal airflow direction can be set using remote control; the vane swings left and right within the angles as stated below. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1 below.

8.1.10. Quiet operation (Cooling Mode/Cooling area of Dry Mode)
A. Purpose
To provide quiet cooling operation compare to normal operation.
B.Control condition
a. Quiet operation start condition
•When “quiet” button at remote control is pressed. Quiet LED illuminates.
b.Quiet operation stop condition
1.When one of the following conditions is satisfied, quiet operation stops:
a.Powerful button is pressed.
b.Stop by OFF/ON switch.
c.Timer “off” activates.
d.Quiet button is pressed again.
2.When quiet operation is stopped, operation is shifted to normal operation with previous setting.
3.When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed.
4.When operation mode is changed, quiet operation is shifted to quiet operation of the new mode.
5.During quiet operation, if timer “on” activates, quiet operation maintains.
6.After off, when on back, quiet operation is not memorised.
C. Control contents
1.Fan speed is changed from normal setting to quiet setting of respective fan speed. This is to reduce sound of Hi, Me, Lo for 3dB.
2.Fan speed for quiet operation is -1 step from setting fan speed.
