How low can I go?

Probably a dumb question, and probably the answer is somewhere simple... but this is quicker, and you folks are great!

I have a nice big Weil-McClain boiler, controlled by a Vaporstat, on a nice big Hoffman (complete with differential!) vapour steam system. Question is: how low can I set the Vaporstat? I know, the lower the better, but there must be a limit? Opinions on what the two controls should be set at welcomed...

Thanks!

    I wouldn't go lower than

    four ounces on the cut-in. Try 10 ounces on the cut-out.

    Thanks Dan! I'll try that -- actually I'm a little lower than that now (9 oz on the main and 8.5 oz on the differential, which says it's subtractive)
