9.7.2 Indoor fan speed can be set as high, medium, low or auto grade, but anti-cold-wind function is preferential.
Auto fan action in heating mode.
9.7.3 The operation frequency of compressor after starting submits to following rule:
When the machine runs, if ∆Th stays in a zone for 3 minutes, action of frequency is as follow:
Zone A: Elevate current frequency one grade, and not stop until the maximum grade.
Zone B: Elevate or keep or descend current frequency.
Zone H: Compressor stops after running with F1 for 60 minutes or when ∆Th＞6℃.
9.7.4 Outdoor unit current control in heating mode.
