and conditions. If it’s plugged in first time, the compressor does not have 3 minutes delay. When
compressor is started, it will not stop within 5 minutes unless it is plugged out.
c. overload protection
If it detects the system current surpass the designed 15 A for continuous 3 minutes, the machine
goes into fan mode, when 3 minutes passed and it detects the current no more than 15 A, it will
back to original state. If it detects overloading states for 6 consecutive times, the machine stops,
and must be restarted by remote controller.
2.dehumidifying mode
(1) the working conditions and control measures
a. if T
in
T
set
+2 , it is in cooling running, the indoor motor speed can be selected .
b. If T
set
-2 T
in
T
set
+2 ,it goes into dehumidifying running ,the indoor motor runs at the low
speed, 6 minutes later the compressor stops, another 15 seconds later the outdoor fan stops
and another 30 seconds later, the indoor motor stops, 3 and a half minutes later, compressor
and outdoor fan run again ,indoor motor runs at low speed, then the machine cycles the
above procedures repeatedly.
c. If T
in
T
set
-2 , compressor ,outdoor motor and indoor motor stop.
(2) in this mode, the reversing valve is inactive , the temp. setting range is from 16
to 30 .
(3) Anti-freezing protection.
If compressor has runs 6 minutes , and detects T
eva
0 ,compressor stops and outdoor mo-
tor stops after 15 seconds, indoor motor runs at low speed ,after 3 minutes delay ,and T
eva
10 ,
it will be back to its original state.
3.heating mode
(1)the working conditions and control measures
a. If T
in
T
set
+2 , it goes into heating mode, reversing valve, compressor and outdoor motor all
work in the same time, indoor fan will run at the same procedures with anti cool air function.
b. If T
in
T
set
+ 4 , compressor stops first, 15 seconds later, outdoor motor stops ,but revers-
ing valve keeps working, indoor motor runs at the procedures of blowing surplus heat.
c. If T
set
+ 2 < T
indoor
< T
set
+4 , keep the previous running state.
(2)in this mode, the temperature setting range is from 16
to 30 .
(3) auxiliary electric heater:
a.The working conditions of auxiliary electric heater: In heating mode, when compressor is
working, indoor motor runs. if it detects T
eva
48 for continuous 8 seconds and T
indoor
22
, electric heater will work.
b. The stopping conditions of auxiliary electric heater: if compressor stops or T
eva
52 or
T
indoor
25 or 2 minutes before defrosting , the electric heater will stop. Once stop, next
startup must be after 2 minutes.
(4)protections
a .anti cool air
when the machine starts heating and T
eva
39 , indoor motor will run at low speed 3
