2) If the compressor stops caused by room temperature rising, indoor fan will be forced to run 127 seconds with
breeze. During this period, anti-cold-wind is disabled. After this, anti-cold –wind function is available.
3) If the machine runs in rating capacity test mode, indoor fan runs with rating speed, and anti-cold-wind is
disabled.
9.7.4 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.
9.7.5 Running rule of compressor after start:
1) After start in heating mode with remote controller, compressor runs at the highest grade Fmax, and frequency
limit caused by Δ T(=room temperature – setting temperature) is disabled within initial 7 minutes, but the pause
of machine and frequency limit caused by protection is valid. After this, frequency changing rule is as the
seventh item.
2) If the machine pauses caused by protection, frequency limit or room temperature meeting setting value and
then resarts, the start frequency of compressor is set as follow and without 7 minutes limit.
9.7.6 After start the operation frequency of compressor submits to following rule:
1) If temperature( Δ Th) zone changes, frequency of compressor will rise or descend one grade, and the maximum
frequency is F10, the minimum is F1. This item is valid after the machine start and running for 7 minutes.
2) When the machine runs, if Δ Th stays in a zone for 3 minutes, action of frequency is as follow:
Zone A – E: Elevate current frequency(excluding F10) one grade, and not stop until Fmax.
Zone F: Keep current frequency invariable.
Zone G: Descend current frequency(excluding F1) one grade.
Zone H: Compressor stops after running with F1 for 60 minutes or when Δ Th

3) Temperature difference ( Δ Tcon) choice.
After power on, the machine will self-diagnose, and if there are no J1 and J2 jump wires, Δ Tcon will be set as 0
