I bought my new 1150 pro series 2 beginning of May this year. I called support and received an upgraded control panel. Installed with no problem. I am now having a 40 to 50 degree temperature difference on the grill. I have not really tried much yet, and it is very irritating with guests I'm trying to show the unit off to. Any suggestions would be much appreciated. I have tried searching on here for help and either nobody has had the problem before or I'm doing it wrong.
