Special attention

For the “compressor out-of-step error” and “module protection error”,

the former is calculated by the main chip of the module panel and the

latter is detected by the power module itself. They are abnormal

operating phenomenon of the compressor essentially. If there is

uncertainty about either error, analyze both together with similar

method. For inverter air conditioners that are in poor electrical

environment or are old, occasional occurrence of such errors is a

normal protection.
