Pioneer mini split error code question

[tmshort]

I have a Pioneer 18K BTU unit that I installed over the summer.
It is running fine.
I never get any error codes on the display on the unit itself.

The app has a “check” feature. Sometimes when I run this test, I get:
Testing: 112
Normal: 111
Abnormal: 1

When I click detail, the abnormal is “The evaporator temperature limit frequency”

I have tried to look this up to no avail. Anyone have any idea what it might mean?

Thanks

Well, here’s an update and I may have answered my own question.

Both times I have noticed this error I have been sitting out here in the shop by the unit. Shortly after checking the app and seeing the error (within 5 minutes or so), the unit went into defrost mode.

After it defrosted, the “error” is no longer present.

I guess the “error” must be some sort of sensor reading that tells the unit to defrost??
