∆T=0 as default.
Note:
When T1-Ts keeps in the same temp. zone for 3 minutes, the compressor will run as the below rules:
A~E: Increase the frequency to the higher level until to F10.
F: Keep the current frequency.
G: Decrease the frequency to the lower level until to F1.
H: Run at F1 for 1h. (If T1-Ts-∆T >6, compressor will stop)
Meanwhile, the compressor running frequency is limited by the current.
If the current increased more than I2HEAT, the frequency will decrease automatically, if the current
raise to over I3HEAT,, the compressor will stop and restart 3min later.
During the frequency decreasing, if the current deceased to between I1HEAT, and I3HEAT,, 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.
