3. The content of trouble code display
3.1 Abnormal sensor: when the sensor is short circuited or cut off, the compressor will
stop, and the trouble code will be displayed.
3.2 Abnormal power module IPM: when the power module comes about such problems
as overheat, over current, short circuit, the compressor will stops, and the trouble code
will be displayed.
3.3 Temperature protection for the compressor exhaust
When the compressor exhaust temperature 90 , the compressor runs at the ascending
frequency;
When the temperature 90 , the compressor runs at the limit to the frequency
ascending;
When the temperature 106 , the compressor runs at the descending frequency;
When the temperature 117 , the compressor stops.
3.4 When the temperature protector at the top of the compressor functions, the
compressor stops and the trouble code is displayed.
