Failure description
AD value is detected below 11(open circuit) or above
1012 (short circuit) for 60 secs.
AD value is detected below 11(open circuit) or above
1012 (short circuit) for 60 secs. Cooling mode operate
without handling this abnormal sensor.
AD value is detected below 11(open circuit) or above
1012 (short circuit) for 60 secs. If tao≤0℃ , no detect of
the open circuit (ad value is blow 11).
AD value is below 11(open circuit) or above 1012(short
circuit), alarm. If Tao<0℃ , no open circuit failure alarm;
if Tao>=0℃ and ET>=0℃ , no open circuit failure alarm
in 5 minutes
AD value is below 11(open circuit) or above 1012(short
circuit), alarm. If Tao<0℃ or not in the normal running
condition, no open circuit failure alarm;
AD value is below 11(open circuit) or above 1012(short
circuit), alarm. No handling of this abnormal sensor when
cooling mode is operating.
