9.4.2.4 Condenser temperature protection 
---55℃<T3<60℃, the compressor frequency will decrease to the lower level until to F1 and then runs 
at F1.If T3<54℃, the compressor will keep running at the current frequency. 
---T3<52℃, the compressor will not limit the frequency and resume to the former frequency. 
---T3>60℃  for 5 seconds, the compressor will stop until T3<52℃.

---T2<0℃, the compressor will stop and restart when T2>=5℃. 
---0℃≦T2<4℃, the compressor frequency will be limited and decreased to the lower level
