----T2> TEH2 ℃ , the compressor running
frequency decreases to the lower level and
runs for 20s.
When the frequency decreases to F2 and the
T2 is still over TEH2℃ for 3 minutes, the
compressor will stop.
----T2<48℃ or T2 stays in 48℃~ TEH2℃ for 6
minutes, the frequency will not be limited by T2.
----T2>60 ℃ , the compressor will stop and
