Hi all, a question.

I have an S17 PRO running off solar 120volt at 600 watt 19Th (2 boards) on BRAIINS+ with NO AUTOTUNING.

Now suddenly it seems to be autotuning for 2 hours while autotuning is still unmarked, temp 65-70C (outside37C). 

Why and between what parameters is it supposed to be autoyuning (even when unchecked)?
Is there anything I should be looking at?

Thanks in advance.
