12. Operation Control
12.1 Basic Function
12.1.1 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.

B. Feedback control
• Immediately after the fan motor started, feedback control is performed once every second.
• During fan motor on, if fan motor feedback 2550 rpm or < 50 rpm continue for 10 seconds, then fan motor error
counter increases, fan motor then stops and restarts. If the fan motor counter becomes 7 times, then H19 – fan motor
error is detected. Operation stops and cannot on back.

12.3.1 Vertical Airflow
Airflow Direction
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. 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 angels of the vane are as stated above. When the air
conditioner is stopped using remote control, the vane will shift to close position.
* Above angle data is for reference only.
