A. Running mode
1. Cooling
2. Dehumidifying
3. Heating
4. Auto
B. Input parameters
1. Indoor ambient temp. T in
2. Evaporator tube temp. T eva
3. Setting temp. T set
4. Condenser tube temp. T con
C. Targets
1. Indoor motor (motor)
2. Swing motor
3. Outdoor motor (single speed motor)
4. Compressor
5. Four-way reversing valve
6. Cooling, dehumidifying indicator; running indicator
7. Digital tube setting temp. indicator or timer indicator
D. Fundamental functions
Cooling mode
1The running conditions and control measures
a. If T in > or = T set + 1oC, the machine runs at the cooling mode. Compressor runs, outdoor
motor runs at low speed, indoor fan runs at the set fan speed.
b. If T in < or = T set –1oC, the machine stops. Compressor stops first, outdoor motor stops after 15
seconds, indoor motor runs at the set fan speed.
c. If T set –1oC < T in < T set +1oC, keep the previous state.
2In this mode, the reversing valve is inactive, the temp. setting range is from 16~30oC.
3Protect function
a. Anti-freezing function.
i. If compressor have run 6 minutes , and detect T eva < 0oC for continuous 3 minutes, then
the compressor, outdoor fan stopped , indoor fan run at the set fan speed. After 3 minutes
later, it will run at the original state if T eva > or = 10oC.
b. Compressor protection
i. Compressor’s starting interval should be more than 3 minutes no matter in whatever modes
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
i. If it detect the system current surpass the designed 13 A for continuous 3 minutes, the
machine 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 6 consecutive times, the
machine stops, and must be restarted by remote controller.

Dehumidifying mode
1The working conditions and control measures
a. If T in > T set + 2oC, it is in cooling running, the indoor motor speed can be selected, and
outdoor motor run at low speed.
b. If T set – 2oC < or = T in < or = T set + 2oC, 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 – 2oC, compressor, outdoor motor and indoor motor stop.
2In this mode, the reversing valve is inactive, the temp. setting range is 16~30oC.
3Anti-freezing protection.
a. If T indoor > T set + 2oC, 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, compressor runs 6 minutes, if it detects T eva < 0oC, compressor and outdoor motor stop,
indoor motor runs at low speed, after 3 minutes delay, and T eva > or = 10oC, it will be back to
its original state.
Heating mode
1The working conditions and control measures
a. If T in < or = T set + 2oC, 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 > or = T set + 4oC, 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 + 2oC < T indoor < T set + 4oC, keep the previous running state.
2In this mode, the temperature setting range is 16~30oC.
3The working conditions of auxiliary electric heater.
a. In heating mode, when compressor is working, indoor motor runs at high speed and middle
speed. If it detect T eva < 50oC for continuous 8 seconds and T indoor < or = 25oC , electric
heater will work, if compressor stop or indoor motor runs at low speed or T eva 54oC or T
indoor 28oC or 10 seconds before defrosting, the electric heater will stop.
4Protections
a. Anti cool air
i. When the machine starts heating and T eva > or = 22oC , indoor motor runs at low speed,
and swing motor makes the louver at the horizontal position, if T eva > or = 40oC or
compressor have run 2 minutes ,indoor motor and swing motor will run at the set speed.
b. Anti high temp.
i. In heating mode, if it detect T eva 56oC (58 can be selected), outdoor motor will stop (in
this period it will not detect the defrosting temp.). If T eva 52oC, outdoor motor will be back
running (it will not detect defrosting temp. in the first 5 seconds).
c. Blowing surplus heat
i. In heating mode, when set temp is reached, comp. stops first, 15 seconds later outdoor fan
stops, Indoor motor blows 90 seconds (60 seconds can be selected) at low speed ,swing
motor makes the louver at the horizontal position.
d. Compressor’s protection is same with the one in cooling mode.
e. Overload protection
i. If it detects that the system current surpassed the designed 13 A for continuous 3 seconds,
compressor, electric heater and outdoor motor stop , indoor motor runs the same procedures
as the blowing surplus heat condition. After 3 minutes and current no more than 13 A, the
machine will be back to its original state, indoor motor runs as the anti cool air condition. If
it detects overloading state for 3 consecutive times within 30 minutes, the machine stops,
and it must be restarted by remote controller.

f. Defrosting conditions and procedures
i. In heating mode, if compressor has run 44 minutes ( in its first 6 minutes it will not detect
defrosting temp.) , and it has detected T con < or = -4oC for continuous 1 minutes, it begins
to defrost, electric heater will stop for 10 seconds ( even if electric heater is not working),
then indoor motor stops, reversing valve becomes inactive in another 2 seconds, another 2
seconds later, outdoor motor stops, when T con > or = 10oC or defrosting lasts for 10
minutes, outdoor motor and reversing valve becomes active, indoor motor will run as the
anti cool air condition, then it cycles again, recalculates the compressor’s running time
again. (In this period, if any protection works, and after the machine is back to work, it will
re-start defrosting state. it will not detect outdoor tube temp when compressor’s in its first 6
minutes running)
g. Noise eliminated protection
i. When you use RUN/STOP button to switch off the machine, reversing valve will become
inactive in 2 minutes.
AUTO mode
1In AUTO mode, standard cooling T set = 25oC, standard heating T set = 20oC.
2Working procedures
a. If T indoor > or = T set + 1oC , select cooling mode, from this time, the set temp. is 25oC. If T
indoor < or = T set – 1oC, compressor and outdoor motor stop, indoor motor runs at the set
speed, if T set -1 < T indoor < T set + 1oC, keep the original state.
b. If T indoor < or = T set + 2oC, select heating mode, from this time, the set temp. is 20oC, if T
indoor > or = T set + 4oC, compressor stops first, outdoor motor stops 15 seconds later,
reversing valve is always active, indoor motor runs as the blowing surplus heat condition. If T
set +2oC < T indoor < T set +4oC, keeps the original state. Cooling only AUTO mode: there is
no heating function in this mode.
3Protections
a. It is same as the one in cooling or heating mode.
4Other controls
1SWING mode
a. When it is active, the louver returns to position O, close the air outlet.
b. When machine works, it turns to the max. Air output position D, then returns back to position L
to stand by (position L is the horizontal place mentioned before).
c. In swing state, the louver swings between position L and position D.
d. When the machine is switched off, it is back to position O.
e. When the machine is running and the swing is off, the louver stops at position E.
