That pretty much controls the IDLE burn. Don't set it too low, you might loose the fire. I think mine is about 8 or 10, when it's warmer to make more heat to pull more draft in the chimney. Typically MIN 6-8 is good for the LL stoves.
The MAX is when you are calling for heat and your FR (Feed Rate) is at 99%, you should NOT be pushing hot coals off the grate. If so, the max has to come down a couple points.
Always make small adjustments and let the stove settle for an hour or more before making any more adjustments. a couple points at a time.
They both are the ON/OFF times or percentages (%). I think Min 6 (secs on), MAX 50 (Seconds off) or something like that.
