6. The basal control modes:
1) Cooling mode:
If T
in
T
set
, cooling mode act, compressor and outdoor unit run, and indoor unit run in the
set speed;
If T
in
T
set
-1 , the unit will be stop from cooling mode, compressor and outdoor unit stop,
and indoor unit still run in the set speed;
If T
set
-1 T
in
T
set
, keep running in the old mode;
In the cooling mode, the range of T
set
is 16 ~30 , the initialize is 25
LCD: 9,000Btu series display “cooling”, ” the set fan speed”, “T
set
”
12,000Btu series display dynamic “the falling snow”, “the fan revolving in the set
speed”, ”the set fan speed”, and “T
set
”
The protecting functions:
Avoiding freezing:
Once the compressor works for 10min, when T
eva
-6 for over 8sec, the compressor
and the outdoor unit fan motor stop, the indoor unit fan motor run in the set speed. After the
compressor stops for 3min and T
eva
8 , everything runs in the old speed.)
Water pump control and the protection for the full water:
The indoor unit water pump will work when the lower water switch is close till the lower
water switch open for 2min.
The outdoor unit water pump will work after the indoor unit water pump works for 1min at
the 1
st
time, the outdoor unit water pump will stop when the compressor stop and it will
linkage with compressor in future.
When the higher water switch is close, the buzzer will alarm “click, click” 8 times, LCD
display the wrong code “E4” in the location of “setting temperature” (for the 9,000Btu series,
LED2 flash), it means the indoor unit water pump does not work and the unit stop till the
protection is canceled.
There is no water pump in the mobile air-conditioner, 1K resistance is used to short the
lower water pump. The higher water pump is close when the water tank is full, the buzzer
alarm “click, click” 8 times LCD display the wrong code “E4” in the location of “setting
temperature” (for the 9,000Btu series, LED2 flash), it means the indoor unit water pump
does not work and the unit stop till the protection is canceled.
The indoor unit and outdoor unit water pumps do not work in the mode of fanning and
heating.
Protecting the compressor:
The distance between 2 times running won’t less than 3min once the compressor work
and it will not stop by the changing of the temperature in the next 6min.
The compressor and the outdoor unit fan motor will stop when it is change from heating
mode to cooling mode.
