I purchased the PB1100PSC3 from Lowes. When I set the PID temperature to a specific temperature like 225 degrees, the grill heats up to about over 30 degrees higher than what I set it to. I have a PB1100PSC2 at my winter home. When I set the temperature on that PID/grill it seems to hold a steady temperature. I've not been able to get through to Pit Boss support yet, so thought I would see if anybody experienced this problem. I've updated the grill to the lastest firmware when I loaded and connected the app. Any insight would be appreciated.
