Protection

8.3.1  3 minutes delay at restart for compressor.
8.3.2  Sensor protection at open circuit and breaking disconnection
8.3.3  Fan Speed is out of control. When Indoor Fan Speed is too high(higher than 2100RPM)or too

low(lower than 300RPM)

lasting 50 seconds, the unit stops and LED displays failure information and

can’t returns to normal operation automatically.
