I'm trying to setup a second temperature controller for my fermentation chamber to have a warmer heating up a carboy to warmer than the chamber temp (which is also used for serving draft) but cooler than ambient room temp. I'm using the directions here on the AHA site as I did before, but the computer cable that I had on hand and chopped up to pull out the wires is a little different.
Instead of the red, white, black, or green colors that I'm used to seeing, this one has white, blue, and a brownish-red color. I can't find anything online about what each of these might represent. My gut was brownish-red would be for grounding (earth color), blue for active, and white for neutral. Has anyone seen or had experience with this combination before?
