Broomell Valve settings

Greetings! Can some explain the settings ( Full ON , OFF, etc.) as you move around the dial on this valve?

Thank you.

    On my Trane valves, they're preset so Full "ON" may not be the highest setting, but that which heats the rads ~80% full. It's calculated for each rad. I don't know how these work so perhaps a pro will jump in.
