Here is a video.
I tried to use it for the first time yesterday. I had it set at 275 and it worked fine for about 5 hours and then it had allot of smoke and then I heard the fire roar and got the erh code. As the fire was roaring and the temp was climbing I could hear the auger as more pellets to it. I think with a PID controller it looks at the temp and only adds pellets when needed. Please correct me if I am wrong.I have done several cooks. The temp swing does not bother me. Everything has come out great. I have posted most of the cooks if you do a search you can see them. Just make sure you have plenty of water in your pan. It help stabilize the temps. The smoker does run hotter in the back. So I just turn the greates half way through.
