Check the F15 (FOD) value before others https://www.thermo-hygro.com 13) F15 (FOD): Time delay seconds for the Fan < 0: in this case, f15 (FOD) is the period for the Fan starts earlier than the compressor starts, Fan stops if defrosting begins.

    14) F13: Fan output modes when f15 (FOD) ≥ 0 0 (CTR): Fan Starts by F14 (FOT), Stop by F16 (FST). 1 (O-N): continuous working except defrosting begins. 2 (C-N): in this case, F15 (FOD) is the time for the Fan to start later than the compressor; the Fan stops if defrosting begins.
