DOH! Steve, I dickchimped it! I had the display in landscape so I couldn't see the results box. It works fine and I'm an idiot!
So, now that it's working I went back and entered the parameters for my last mash....13.75 lb., 71F grain temp, 1.6 ratio, and 148 target temp. BrewBot said strike at 157.2. Promash told me 161. 161 was what I used when I brewed and it was right on. I'm guessing it's because Promash takes into account the thermal mass of my cooler.
Lennie, you said that when you used it it was right on for strike temp. What kind of mash tun do you use?
