First time kegging. Keg build completed. Hopefully kegging all 3 batches, currently fermenting, tonight. Question is, what is a good or average setting on Johnson dig. Control. Not fermenting right now, just being used as keg storage/ server. I like cold beer. Set it at 38° before bed to test Johnson controller hooked to keezer. Initial temp was like 75°, in morning, it was as set 38°. This thing is sealed up tighter than a frog's butt! If somebody could simplify the SO,OFS & ASD to drink beer at 38° - 39°.
