I tried to reset mine but didn’t get very far.......the old version had dip switches for setting the temperature. The new style has up and down buttons on the display screen. It is easy to change temps on it.
That one has been out for quite some time now.
If the temperature is off on the Genesis 1588, you can reset it too:

Due to my flock having Mareks, I will no longer be joining this hatch a long. Please take my name off the list. (I was planning on hatching 6 naked neck crosses for agility). However.........some good news: I have a broody sitting on some eggs. They will probably hatch in 2 weeks. I'll send pics if/when they hatch!!! So sad to miss this. I'll keep you posted though, I may decide to hatch and just hope for the best.
