If users switch on AC by remote controller, the compressor will run at the Fmax frequency for 7
minutes according to the outdoor ambient temp. During the 7 minutes, the frequency limitation is active.
7 minutes later, the compressor running frequency will be controlled as below:
3.5
3.0
2.5
2.0
1.5
1.0
0.5

While the zones of A,B,C... are corresponding to different compressor running frequency.
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 F8.
F: Keep the current frequency.
G: Decrease the frequency to the lower level until to F1.
