I just brewed a Bohemian Pils and here are my fermentation steps:
I used WL802, which ferments really clean between 50F - 55F and produces very little diacetyl.
I fermented at 53 and held it within a 1-degree window.
7/15: OG -- 1.050
7/27: Let temperature rise on its own to 60F for diacetal rest, though a tasting at the time revealed no diacetyl.
7/30: FG -- 1.010. Cold crashed the primary down to 32F to drop yeast and plan to move it to secondaries for lagering this weekend. It will be in the secondaries for a minimum of 5 weeks and then I'll keg/carbonate it.
At this point, the beer tastes great and will not doubt be a killer pils starting in mid September.
BTW, a lot of this depends on the yeast strain you use and its penchant for producing diacetyl, but I've always found it wise to do a diacetyl rest no matter which yeast I've used. It just gives the yeast a chance to clean up a bit so the beer can finish as cleanly as possible.
