Chapter 2 Operating Principle
. Cooling
After the power supply is switched on, the machine is set to COOL
mode. With the compressor being operated, the low-temperature and
low-pressure refrigerant vapor is sucked into the compressor where it is

turned into high-temperature and high-pressure gas. Then it is cooled
down in the outdoor heat exchanger by the air and becomes liquid. After
being throttled by the capillary, the refrigerant liquid comes into the
indoor unit and then it evaporates in the indoor heat, exchanger,
absorbing heat and reducing the room temperature. The evaporated
refrigerant vapor returns to the outdoor unit and is again sucked into the
compressor, completing the cycle. With the refrigerant cycling being kept
on, the objective of lowering the room temperature is fulfilled.
. Heating
After the power supply is switched on, the machine is set to HEAT
mode and the coil of the electromagnetic four-way valve is energized.
After the compressor starts to operate, the high-temperature and
high-pressure refrigerant gas first comes into the heat exchanger of the
indoor unit, where it is cooled, releases heat and increases the room
temperature. The cooled high-pressure refrigerant is then throttle1d in the
outdoor unit and returns to the compressor after evaporation. With such
cycles being maintained, the objective of increasing the room temperature
is fulfilled.

Operation Hints

Chapter 3 operation details
1. Overall
1.1Protection of compressor
Whatever operation modes the air- conditioner is under, there will
always be 3 minutes' time- delay protection unless it is on for the first
time. When the compressor is switched on, it can not be shut down
within 3 minutes (except under the modes of heating or defrosting)
unless it is powered off or its operation mode is changed.
1.2The operation indicator will turn light when the air conditioner is
powered on.
1.3The buzzer will sound immediately after the controlling device
receives a correct and effective signal sent by the remote control.
1.4Timing function can be applicable to all operation modes while
sleep function can only be applicable to the modes of refrigeration
and heating.
2. Automatic operation mode
2.1 When the air conditioner works, it can detect the indoor temperature
automatically whereby its operation mode can be selected:
refrigeration, heating or dehumidification.
2.2 When the indoor temperature reaches more than 27, the air
conditioner will operate under the mode of refrigeration.
2.3 When the indoor temperature reaches between 20and 27the air

conditioner will work under the mode of dehumidification (always
mute).
2.4 When the indoor temperature reaches less than 20, the air
conditioner will work under the mode of heating.
2.5 Under this mode, the air conditioner will operate in the respect of
blowing rate as set and its pendulum leaves will work according to
the requirements of automatic ventilation door.
2.6 Once the operation mode is selected, it will not be able to be
changed. When the air conditioner is shut down and then restarted,
the operation mode will be selected once again based on the
variation of indoor temperature.
2.7 After the operation indicator has been flickering for 20 seconds, it
will turn light steadily (i.e. the determination of operation mode will
start in 20 seconds.)
2.8 This mode has timing function, does not have sleep function.
2.9 Under this operation mode, the temperature can be set and adjusted
by remote control.
3. Refrigeration mode
3.1 Under the refrigeration mode, the range of temperature set by
remote control is between 16and 32.
3.2 Shut-down of four-way valve;
3.3 The condition on which the compressor starts is that the indoor

temperature reaches more than the temperature set plus 1while the
condition on which the compressor shuts down is that the indoor
temperature reaches less than the temperature set minus 1.And
when the indoor temperature is equal to that set, the original
operation mode will be kept.
3.4 Under the mode of refrigeration, the function of preventing indoor
coiled pipe from being frozen will be effective.
3.5 The indoor wind speed will be as set. And the pendulum leaves will
work according to the instructions sent by remote control.
4. Dehumidification operation
4.1 The temperature range set and controlled is between 16and 32.
The temperature will be set by remote control.
4.2 The four-way valve is shut down.
4.3 The wind speed gear-changes to “mute". And the pendulum leaves
works according to the instructions sent by remote control;
4.4 The function of preventing indoor coiled pipe from being frozen is
effective.
4.5 When the indoor temperature reaches less than 16, the function of
dehumidification is out of use.
4.6 When the indoor temperature reaches more than 16 , the
compressor will be switched on and work intermittently. The time
when the compressor shuts down depends on T ring and T ring-T set.

When the compressor is shut down, the outdoor fan and indoor fan
will stop working.
When T ring≥23
T set <T ring-1, the compressor will be working for 8 minutes and then
stopping for 3 minutes in cycles.
T set≥T ring-1, the compressor will be working for 3 minutes and then
stopping for 6 minutes in cycles.
And when T ring <23
T set ≤T ring-1, the compressor will be working for 3 minutes and
then stopping for 4 minutes in cycles.
T set >T ring-1, the compressor will be working for 3 minutes and then
stopping for 6 minutes in cycles.
5. Function of ventilation control
5.1 Under the mode of ventilation, the outdoor fan assembly will
always be shut down.
5.2 The indoor fan will operate as set in the respect of air quantity
without the gear- change of “high power".
5.3 The pendulum leaves will work according to the instructions sent
by remote control.
6. Heating function
6.1 Under the mode of heating, the temperature range set is between 16
and 32. And the temperature will be set by remote control.

6.2 When the air conditioner is powered on, the outdoor fan, four- way
valve and compressor will start at the same time while when it is
shut down, the outdoor fan and compressor will be shut down at the
same time and so will the four- way valve after 2 minutes' delay.
6.3 Under the mode of heating, the compressor can not be shut down
within 3 minutes after it is powered on unless the operation mode is
changed or the air conditioner is turned off.
6.4 There is a 3temperature compensating function. The temperature
measured at the in-blow vent minus 3automatically can be
regarded as that compared with the temperature set (This function
does not exist under other circumstances).
6.5 According to the temperature set, the condition upon which the
compressor will be switched on is indoor temperature≤temperature
set-1While the condition upon which it will be switched off
is indoor temperature is indoor temperature≥temperature + 1.
When the indoor temperature is equal to that set, the original
operation mode will be kept.
6.6 Indoor fan control:
6.6.1 Heating operation and prevention of cold wind
When the compressor works:
1. During the rising process of the temperature of coiled pipe,
the indoor fan will not start if the temperature of the coiled

pipes is less than 25.
2. When the temperature of coiled pipe reaches less than 35
But more than 25, The indoor fan will work under the
mode of “ mute". If the temperature of coiled pipe ascends
to 25and then descends, it will stop working only when
the temperature is lowered to 22.
3. When the temperature of coiled pipe reaches more than 35
, the indoor fan will operate as set in the respect of wind
speed. If the temperature of coiled pipe ascends to 35
And then descends, it will enter into the operation mode of
“ mute" only when the temperature is lowered to 30.
6.6.2 Afterheat-blowing function:
6.6.2.1 When the compressor stop working:
1. When the temperature of coiled pipe is more than 35, the indoor
fan will operate as set in respect of wind speed.
2. When the temperature of coiled pipe is more than 25, but less
than 35, The indoor fan will operate under the mode of “ mute"
3. When the temperature of coiled pipe is less than 25, the indoor
fan will stop working.
6.6.2.2 The afterheat-blowing function when the air conditioner is just
shut down: If the temperature of indoor coiled pipe reaches more
than 30, The indoor fan will operate under the mode of “ mute"; If

it lowers to less than 30, the indoor fan will be shut down; And the
time when the afterheat blows will last less than 40 seconds after
the indoor fan is turned off.
6.7 Defrosting operation:
6.7.1The conditions upon which the outdoor sensor goes into operation are
as below:
1. Under the circumstance of heating, if T external coiled pipe is at the
temperature of less than -6which lasts 2 minutes and the
accumulated working time of compressor reaches more than 50
minutes (if there is any power cut-off or shut-down by remote
control, the accumulated working time of compressor shall be
re-calculated), the defrosting interval will be more than 50 minutes
and the compressor will be working 5 minutes continually.
2. If there is any damage to the external coiled pipe, the accumulated
working time of compressor will reach 50 minutes (if there is any
power cut-off, shut-down by remote control or defrosting, the
accumulated working time of compressor shall be re-calculated)
and the defrosting operation will last 10 minutes.
6.7.2 Once one of the following conditions is satisfied, the defrosting will
end:
1. The temperature of T external coiled pipe is more than 12.
2. Defrosting duration is more than 12 minutes.

6.7.3 The requirements of defrosting operation:
