33
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<-2 , compressor will stop)
Meanwhile, the compressor running frequency is limited by the current.
Off: Compressor stop.
Decrease: Decrease the running frequency to the lower level.
Hold: Keep the current frequency.
Resume: No limitation for frequency.
Note:
When AC is in “hold” zone for 3 minutes, the compressor frequency will rise to the higher level.
(frequency will increase twice at most)
