B. Feedback control
• Immediately after the fan motor is 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, the fan motor error
counter increased, fan motor is then stop and restart. If the fan motor counter becomes 7 times, then H19 - fan
motor error is detected. Operation stops and cannot on back.
11.3 Outdoor Fan Motor Operation
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.
11.4 Airflow Direction
• There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by
vertical vanes).
• 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).

• Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the
angles as stated above. When the air conditioner is stopped using remote control, the vane will shift to close
position.
• 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.
