/the impression that on the 0 degrees orientation
is with the legs of the LTZ above the metal can.
Or did I mis-interpret the description?
On the other side the PCB could be mounted
vertically in the case.
So how is the orientation of the LTZ with respect
to the 0 degrees?

best regards

The LTZ is mounted upside-down, and so it is in the 0° position.
You are correct.

A great term for this effect is geotropism. Technically only the graviational effect, not thermal though.

Seems to me that the thermal effect you are talking of is
gravitationally induced.

I read somewhere that the LTZ1000 chip is mounted in a special way
to reduce thermal conductivity. That would sort of indicate some
kind of edge mount with the chip floating, and that again would
certainly expose it to gravitational effects.

In that case, it should only have three modes: up, down and sideways,
where the chip is vertical, but the rotation around the center
axis should have very little effect.
