2. pressure switch contact disconnected, short circuit or open circuit of the
routing
3. open circuit of clutch’s winding
4. switch burned down
5. master relay burned down
6. slide of the clutch
7. belt of the compressor broke or too loose
8. compressor failure
9. sensor failure(judged by reading the failure code)
10. insufficient cold media, lower systempressure(< 0.97MPa)
11. system pressure above 1.37MPa
12. water temperature of the engine too high
13.V oltage of the clutch below 7V
2. Pick-up of Compressor
1. normally-open contact of the compressor’ s relay stuck and serious leakage
of system cold media, systemrunning short of cold media

Refrigeration of
air conditioning
system failed
3. no wind from the blower
1. fuse burned down
2. motor brush of the blower damaged
3. switch of the blower damaged

5. speed-adjusting module damaged
6. no wind fromthe blower when at high speed, high-speed relay damaged
Press down “Temp+” switch
Step 11: display “11”(set the temperature zone)
Action of the executor mechanism:
Mode damper: defrost
Circulation damper: external circulation
Temperature damper: cold end
Wind amount: the minimum
Compressor: off
Attention: during the inspection period from step 7 to step 11, the controller will forcibly transit the output signal based on
the code number displayed on the integrated display screen to the functioned executor; the inspection must be done with
such methods as visual inspection, listening to abnormal sound or touching the air vent by hand so as to judge whether
there is any improper operation.
