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.
H: Run at F1 for 1h.(if T1-Ts<-2°C(28.4°F), the
compressor will stop)
Meanwhile, the compressor running frequency
is limited by the current.
I3COOL
I2COOL
I1COOL
I3COOL, I2COOL,I1COOL mean different
running current value.
Off: Compressor stops.
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)
