Doval oval chainset

I've just purchased a Soezialized Venge fitted with a Doval oval chainset, but don't know what the high and low inertia mean?
Wondered if anyone out there could shed some light on it for me.
The bike is set up in hole 4 high Inertia, the bike is like lightning of the flat, but struggles on hills.
Any responses welcomed

If memory servers, you start on the lowest and work your way up until if feels right, some set ups can hurt certain people's knees etc.
