Do you own the DIGIQ II or another one of their models. If you own the DIGIQ II just make sure you have the ramp mode turned off, or it will drive you crazy. When I first got mine, over two years now, I didn't know about it and when I did my first cooks, I kept losing pit temps once I got within 25* of my target temp. That is how it is designed so that you don't overshoot your meat temp. In other words, if you have your meat temp set at 190, once it reaches 165, the pit temp will drop so that the meat temp doesn't overshoot. It's a great feature, I just didn't know about it and there just wasn't enough info provided with the purchase. I found myself bumping up the pit temp and checking how much fuel was left in the charcoal ring. Once I found out what was going on, I reset it and have had no issues since other than a probe going goofy on me and they replaced it quickly and made sure it was calibrated and working well.
I just set it and forget it if that answers your question. I have a 4 cfm fan and leave it wide open, and just leave the top vent cracked just enough to keep the fire going, as the bottom vents are completely shut down.
