go into fan mode, when 3 minutes passed and it detect the current no more than 13 A, it will back
to original state. If it detects overloading states for 3 consecutive times within 30 minutes, the
machine stops, and must be restarted by remote controller.

consecutive times, the whole machine stops and can not run again automatically.
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 ,and outdoor
motor run at low speed.
b. If T
set
-2 T
in
T
set
+2 ,it goes into dehumidifying running ,the indoor motor run 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 the low speed, then the machine cycle the
above procedures repeatedly. outdoor motor runs at the low speed.
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 16~30 .
(3) Anti-freezing protection.
If T
indoor
T
set
+ 2 , it goes into cooling running , anti-freezing function is same with cooling
mode, but the compressor must stops for 4 minutes. when it goes into dehumidifying mode, com-
pressor runs 6 minutes , if it detects T
eva
0 ,compressor stop, outdoor stop 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 late, outdoor motor stops ,but reversing
valve keeps working, indoor motor run 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 16~30 .
(3) The working conditions of auxiliary electric heater.
In heating mode, when compressor is working, indoor motor runs at high speed and middle speed
.if it detect T
eva
<48 for continuous 8 seconds and T
indoor
22 , electric heater will work ,if com-
pressor stop or indoor motor runs at low speed or T
eva
52 or T
indoor
25 or 10 seconds
