Notes
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.
2
Sensor on the indoor unit dects the e vaporator temperature continuously, once the temperature is lower than some point for certain time, it will turn off the system to avoid freezing the indoorunit.
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.

Explanation
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.
7
For multi split airconditioners,when one of the indoors is working for cooling(dehumidifying),other indoor unit can no work for heating.
8
While heating, indoor tube temperature sensor will detec
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.

For invertor system, the frequecy will lower down when the voltage drop sharply, so that the current can k eep stable.

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.
7
For invertors only.After a period of cooling, the system will work in higher frequecy for a period.
8
For invertors only. Lower the freqecy, reduce the load if the current is higher than standard.
9
For invertors only. Lower frequecny, if exhaust temperature is higher than standard.
