Hello all for any one with the ace did you get that problem with it not recognising it's at the boil and not starting the step/timer. If so I'm guessing increase the temp calibration by one or two degrees but allowing for this with mash temps too. Mine was at boiling and showed 99 degree and calibration set to 0. It did fill it with a few litres of water before hand and used two other thermometers to check it's own reading and it was .5 degrees higher than the other two thermometers. Pretty good really. Has anyone had this too. How did you ajust it. Cheers guys
