Auto Fan Speed

2. During heating operation, the indoor fan will run at the following speed when the compressor stops.

3. Hot Start
When the heating operation starts, the indoor fan stops and the compressor run with the frequency of 117Hz.
This is to prevent the cold airflow from blowing.
If the piping temperature rises to 19

к

, and the indoor fan speed and airflow direction varies with the indoor piping

temperature, the hot start control is completed.

13.3.2 Overload Protection Control

The frequency for the compressor is determined by indoor piping temperature.
