Sump (oil) temperature sensor dislocation error
Criteria
Cause of problem
Refer to how to determine below
Outdoor unit display
1. How to diagnose
1) If the Sump temperature right before the start of compressor = Tsump.ini, current compressor's SUMP temp =Tsump. real,
When the difference between Tsump.ini and Tsump.real is an absolute value so that it cannot be more than 2˚C,
In other words, the condition of Tsump.real-Tsump.ini<2˚C has been satisfied for 60 minutes since a compressor started, it is diag-
nosed as an error.
After 60 minutes of compressor operation, there will be no Sump sensor dislocation detection.
2. How to check
1) Check if a sensor of the relevant compressor has been dislocated in accordance with error code, assemble and correct the error.
