temperature being detected by the discharge pipe thermistor.
Malfunction
Decision
Conditions
If a stop takes place 4 times successively due to abnormal discharge pipe temperature, the
system will be shut down.
If the temperature being detected by the discharge pipe thermistor rises above
°C, the
compressor will stop. (The error is cleared when the temperature has dropped below
°C.)
The error counter will reset itself if this or any other error does not occur during the following
60-minute compressor running time (total time).
