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
,
℃
the compressor will stop)
Meanwhile, the compressor running frequency is limited by the current.

Off: Compressor stops.
Decrease: Decrease the running frequency to the lower level.
Hold: Keep the current frequency.
