Starts to go around 26 degrees, and by 28 it's done. Equates to a 4mm movement around the wheel, so 4 yds at the top end, and naff all down the bottom. Only had it down to 2 degrees but it didn't stay there for long. Looked like it wanted to move, but until i get her really cold I wont know.
The upper temp shift is like a switch so you either keep it under or push it over.
It's fairly predictable and easy to work with.
