Electronic controller:
1.Automatic mode
1) Initial RT determines the working mode and ST,the mode is determined effective only once unless
A/C shut-down then re-started. If from other modes switches to autoamatic mode (including mode
conversion after shutdown), it should be that the compress stop more than 3 min then temperature
judgement and automatic mode are conducted (it can conduct immediately from fan mode switched
to automatic, the indoor fan stops, three minutes later the response is made and start up). Within 3
min, the output as: Showing the room temperature, indoor fans starts (or anti-cold airflow), the
outdoor fan stops;
2) With memory controller, once being turned off or in case of an accidently power cut, the A/C is able
to retain and restore the original mode when being turned on or the power supply is resumed, if the
auto restart function activated. power-down after power-on; while if the auto restart fundction isn’t
activated, the A/C enters standby state.

Under automatic mode (including from automatic converted into dehumidifying Dry mode), when the
temperature up and down signals from the remote controller is received, the setting temperature ST
adjusts correspondingly to the current room temperature plus or minus 1℃, the automatic regulating
temperature range is ± 2℃.
2．Cooling mode
1) The control of the compressor
a. When RT－ST≥1℃，the compressor is running.
b. When RT－ST＜－1℃，the compressor is off.
c. When －1℃≤RT－ST＜1℃, the compressor keeps its original state.
2) Outdoor fan motor and the compressor run simultaneously (except for defrosting).
3) The control of indoor fan motor:
a. Indoor fan motor can operate by automatic, low, middle, and high airflow speed circularly.
b. Indoor fan motor’s the automatic airflow speed control Indoor fan motor can operate by automatic，

When the temperature changes lead to changes in airflow speed, the switch can only be made

3. Dry mode
running into this mode, the Air cond. firstly operates for 3 minutes according to cooling mode (set
temperature is 16℃ or 18℃) , and then takes the detected backflow air temperature minus 2℃ as a
new set temperature (the minimum value of 16℃) and runs according to cooling mode, indoor fan
operates at low-speed, at this moment the setting operation of Fan speed is invalid but Swing is
adjustable.
4. Heating mode
On the Heating mode, the room temperature is repaired. After repaired, the room temperature
display on the LED CRT=RT-3℃.
1) The control of the compressor
a. When ST－CRT≥1℃，the compressor is running.
b. When ST－CRT＜-1℃，the compressor is off.
c. When -1℃≤ST－CRT＜1℃, the compressor keeps its original state
2) Outdoor fan motor and the compressor run simultaneously (except for defrosting)
3) The control of indoor fan motor:
a. Indoor fan motor can operate by automatic, low, middle, and high airflow speed circularly.
b. indoor fan motor’s the automatic airflow speed control Indoor fan motor can operate by automatic，

When the temperature changes lead to changes in airflow speed, the switch can only be made

4) Vane motor control: run as set state.
5) 4-way valve control:
a. Under heating mode, the four-way valve maintains well-connected status (including the
compressor stops on set condition, but except for the defrosting process)
b. When the mode switches into the heating mode or start-up, four-way valves will open 5 Seconds
before the compressor starts; while the mode exits from the heating mode or turn off, the four-way
valve will close 2min after after the shut-down the compressor.
6) Defrosting function:
During defrosting, once mode switch, temperature setting signals received, and the buzzer and
display make response immediately, but the other operations won’t implemented until defrosting
finished;
During defrosting, the signals of on-off, timing, sleep, airflow speed ans swing will be responded, but
the airflow speed and swing should be in accordance with anti-cold air rules.
Except the above signal processing during defrosting, no other signals will be dealt with, but only a
loud buzz.
During defrosting, electrical heating stops compulsively.
Defrosting enter and exit pragram:
Option 1：with jumper JC

Air Conditioner Service Manual
The condition of enter defrosting: run into defrosting once any of condition 1, 2, and 3 met.
Condition 1：As shown in figure 3
Defination:
The followings are all required to meet:
a. IPT1 settles for IPT1＝IPTmax－△IPT（8℃）
b. t5≥50min（running time t5≥50min（the compressor runs cumulatively），t5 is removable，and could
be less than t1）
c. IPT＜40℃，and lasts 2min。
Running into defrosting on condition 1, the first running time of set defrosting is F (8min); after running
a defrosting cycle, the defrosting time should be determined and adjusted.
Figure 3
Condition 2: When running time is more than or equal to 120 min (compressor is running
accumulatively), the indoor temperature is less than 35 ° C for 2 min sustained. Running into
defrosting under condition 2, defrosting time set is 8 min.
Condition 3: after the compressor is operating for 20min continuously, the indoor temperature is less
than 23 ° C which is anti-cold wind temperature when the fan stops running(including temperature
droping when compressor operating, not including the compressor’s starting course), and the
machine runs into defrosting according to any one condiciton as below) Running into defrosting under
condition 3, defrosting time set is 10 min.
