C. Fan Motor Control
1. Motor specification
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 seconds.
PWM motor. It is done once every 0.5 seconds.
b. Offset duty T max/min limit
High voltage PWM motor has maximum offset duty.
(Refer to indoor fan motor control basic rotation speed.)
(Refer to 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 2,550 rpm or when less than 50 rpm.
Control: Fans stop.
Return: Restart after 5 seconds.
* It will not detect out of rhythm condition within 5 seconds 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.

9.1.1.8. 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
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.
