Excellent, I tried. But it behaves the same way !!

I noticed that by entering your firmware the fuses are set automatically as I manually set them.
And that's OK.

But the behavior seems identical to that compiled by me. After an initial click, the relay goes ON even when the temperature is lower than 30 ° and when it exceeds 30 ° nothing happens.
