During the 7 minutes, the frequency limitation is
active.
7 minutes later, the compressor running
frequency will be controlled as below:
+5.0
+4.5
+3.5
+3.0
+2.5
+2.0
+1.5
+1.0
H
G
H
F
E
D
C
B
A
+0.5
While the zones of A,B,C... are corresponding
to different compressor running frequency.
ΔT=0℃ 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.
I3HEAT
I2HEAT
I1HEAT
Off
Decrease
Hold
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.
Resume: No limitation for frequency.
Note:
When AC is in “hold” zone for 3 minutes, the
compressor frequency will rise to the higher
level. (The frequency will increase twice at
most)
