It's dissappointing/unfortunate that they went with a 4 wire plug as opposed to the 3 wire 220v w/ a separate 120v circuit like the SSbrewtech controller. I thought the original controller was 3 wire. This definitely takes this system off my list. (Of course maybe the controller could just be rewired to accommodate those type of connections.)
The thing is, no one will ever be happy with the way they do it. I sell a lot of brew commanders and a good one in 4 or 5 units are ordered with our optional 4-wire conversion that changes the separate L6-30P and 5-15P circuits into a single 14-30P. Folks having a new circuit put in hate being forced to setting up two different circuits when a single 4-wire will do.
