[Heating]
• According to indoor pipe temperature, automatic heating fan speed is determined as follows.
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
increase, 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.
12.3. 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.
12.4. 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).
12.4.1. Vertical Airflow
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 depands 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.
