No one said that.

You didn't include your configs in the original report like the issue template requested, so we can only guess as to what the issue could be.

He didn't mean to imply that, it's just normal good tshooting practice to rule out obvious/simple fixes first especially when going on minimal information.

its ok. Don't worry about it . I found this problem has been around for a long time. Possible since version 2.0.6, Im not sure.

Duplicate of #21799

ErsaFap commented 2 years ago

Its not duplicate (I think), the regulator is doing great but target temperature is incorrect. It heats up to 90 degrees in 6 minutes. Power is enough. But it should heat up to 100.
