1.1.2.1 Air volume control under cooling running (Cool compensation temp. –0.33
When setting manual control, wind speed will run according to the setting value during compressor running, and
run in the speed of setting value minus 60rpm during compressor stopping.
When setting automatic wind speed, its velocity is related to temperature difference ΔT ( ambient temp.－
compensation temp.－setting temp. ). See the following table for details:

1.1.3 Dehumidification running
1.1.3.1 Air volume control under dehumidification running (Cool compensation temperature –0.33ｏC)
Except for the first running that fan runs in low speed during compressor stopping, fan stops during compressor
OFF.
When setting manual control, wind speed runs according to the following table during compressor running:
