8.4.3 Heating Mode
8.4.3.1 Compressor running rules:
The maximum operation frequency of the compressor after starting submits to the following rule.
Fmax=F3
Fmax=F5
Fmax=F7
Fmax=F9
Fmax=F10

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