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
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:
I2HEAT
I1HEAT
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.
