Hey all, hope you had a great Thanksgiving. So on my first cook yesterday with my brand new Competition 850 I noticed that the display showed 225 and my other two thermometers, one on the grill and the other a Thermopro, showed 255. Both of the thermometers were within 3 to 4 degrees apart but the temp on the control board was 20 to 25 degrees lower the the thermometers. These were the grill temps and not the meat. Is there a calibration for the temp anywhere that I have missed?
