If the current increased more than I2COOL, the frequency will decrease automatically, if the current
raise to over I3COOL, the compressor will stop and restart 3min later.
During the frequency decreasing, if the current deceased to between I1COOL and I2COOL, the
frequency will hold. If the frequency not changed for 3min, the frequency will increase to a higher level,
and it can increase twice at most.
If the current deceased to lower than I1COOL, the frequency limit will be invalid.
