1.3.2.3 Evaporator Low Temperature T2 Protection.
---T2<0℃, the compressor stops and restarts only when T2≥5℃.
---0℃≤T2<4℃, the compressor frequency is limited and decreases to a lower level
---4℃≤T2<7℃, the compressor maintains its current frequency.
---T2>7℃, the compressor frequency is not limited.
