Notes |
Explanation |
| E1 |
High Pressure protect |
1 |
|
|
|
It is a sensor put aside the exhaust pipe.Once the pressure of exhaust pipe surpass 3.15Mpa, the airconditioning system will stop working. |
| E2 |
Inside Anti-Freeze Protect |
2 |
|
|
|
Sensor on the indoor unit dects the evaporator temperature continuously, once the temperature is lower than some point for certain time, it will turn off the system to avoid freezing the indoorunit. |
| E3 |
Low Pressure Protect |
3 |
|
|
|
For system with low pressure sensor(locating aside the inspiration pipe), once the pipe's pressure is lower than 0.15Mpa, the system will stop working. |
| E4 |
Compressor Discharge protect |
4 |
|
|
6 sec Pause before Flash Sequence |
Once the exhaust temperature of the compressor is higher than regulated, the system will be turned off automatically. |
| E5 |
low pressure over current protect |
5 |
|
|
|
Once the system current is higher than regulated,the system stops. |
| E6 |
indoor-outdoor communication Error |
6 |
|
|
|
Bad communication between indoor and outdoor units. |
| E7 |
Mode conflict |
7 |
|
|
|
For multi split airconditioners,when one of the indoors is working for cooling(dehumidifying),other indoor unit can no work for heating. |
| E8 |
high Temp protect |
8 |
|
|
|
While heating, indoor tube temperature sensor will detec |
| E9 |
cold wind protect |
9 |
|
|
|
While heating, the indoor fan will work several minutes later than the compressor so that the airflow comes out the airconditioner will not be too cold. |
| E0 |
AC Voltage Low |
10 |
|
|
|
For invertor system, the frequecy will lower down when the voltage drop sharply, so that the current can keep stable. |
| H6 |
No Indoor motor feedback |

| F6 |
Cooling Overload |
|
6 |
|
|
For invertor, while cooling, the outdoor tube temperature sensor detect the tempearture continuously, and will low the working frequency if the tube temperature is higher than some point for certain time. |
| F7 |
Unused |
|
7 |
|
|
For invertors only.After a period of cooling, the system will work in higher frequecy for a period. |
| F8 |
Current Overlaod |
|
8 |
|
|
For invertors only. Lower the freqecy, reduce the load if the current is higher than standard. |
| F9 |
Unused |
|
9 |
|
|
For invertors only. Lower frequecny, if exhaust temperature is higher than standard. |
| F0 |
Unused |
|
10 |
|
|
|
| H1 |
Defrost |
|
|
1 |
|
In heating condition, defrosting auotmatically and keep the heat exchange efficeincy. |
| H2 |
Static duct clean protect |
|
|
2 |
|
|
| H3 |
compressor overload protect |
|
|
3 |
|
Compressor stop working when the compressor temperature is higher than regulated. |
| H4 |
System Abnormal |
|
|
4 |
|
While cooling, system stops if the outdoor tube temperature is higher than a certain point for certain time. While heating, system stops if the indoor tube temperature is higher than a certain point for certain time. |
| H5 |
Mode Protect |
|
|
5 |
|
For invertors only. |
| H6 |
Unused |
|
|
6 |
6 sec Pause before Flash Sequence |

7 |
|
|
| H8 |
Water full protect |
|
|
8 |
|
For system with water pump,such as cassette airconditiners, the system stop working when the water level surpassed regulated level. |
| H9 |
heating Error |
|
|
9 |
|
|
| HO |
Heat high temp protect |
|
|
10 |
|
For invertors only. While heating, lower the frequency if the indoor tube temperature is higher than standard. |
| FA |
Pipe Hot |
|
|
|
|
For invertors only.While cooling, lower the frequency if the outdoor tube temperatuer is higher than standard. |
| FH |
Freeze Protect |
|
|
|
|
For invertors only. While cooling, lower frequency if the indoor tube tempearture is lower than standard. |
