To be able to brew at 120v remotely where 240v isn't available.

I'm glad Jeff chimed in - we hashed this out with some other smart folks in the thread he referenced, and I think the end idea was pretty nice - a simple design that prevented you from accidentally screwing something up and shooting 240v into a 120v element. With a relay/contactor, a switch, and some creative wiring it all worked out quite nicely.

Of course, I look at my system and there's no way I'd ever be able to move it around, nor would I want to, so having multiple input voltages doesn't make a lick of sense to me unless you've managed to build a very compact panel and are doing a single kettle BIAB type setup. Or you mount your brewery into the back of a pickup truck or conversion van.
