Fmax: The maximum operation frequency of 
compressor. 
F1~F8: The detailed value of the compressor 
operation frequency. 
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:

While the zones of A,B,C... are corresponding 
to different compressor running frequency. 
ΔT=0°C(32°F) 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-ΔT >6°C(42.8°F), 
the compressor will stop) 
Meanwhile, the compressor running frequency 
is limited by the current.   
I3HEAT
I2HEAT
I1HEAT
Off
         Decrease

Resume
 
I3HEAT, I2HEAT,I1HEAT mean different 
running current value. 
Off: Compressor stops.   
Decrease: Decrease the running frequency to 
the lower level.   
Hold: Keep the current frequency.
