8.4.2.4 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 .
8.4.2.5 Evaporator temperature protection
