๎
The radiation fin temperature with the compressor on is above 103ยฐC.
๎
The error is cleared when the temperature drops below 95ยฐC.
๎
If a radiation fin temperature rise takes place 255 times successively, the system will be shut
down.
๎
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).
