Default Heated mirrors constantly on ? S8 D2 FL

My mirrors are getting very hot when the car is running - the heating is constantly on. Is this normal ?
In previous cars that I've owned the mirrors only used to come on once I've switched the heated rear screen on.

I think mine are always on, but there's a little thermostat in the back of the mirror glass.
I believe I've seen them steaming even when the rear window demist isn't on, but that would be rare.

They automatically come on below a certain outside temperature regardless of the heated screen settings with the D2.

This changed on the D3, where they work in conjunction with the rear demister.

I thought i remember reading in the book that the knob has to be in the central position, mine is almost always set on tip so i don't scuff my wheels on the kerb and therefore never thought they were heating regardless of rear screen. I might be talking a load of
