Strangely, whenever you switch cooking temp, the auger runs continuously for four minutes before trying to adjust to the new set temp. This isn't so bad if you're going from low to high, but problematic in the opposite direction. We were slow smoking ribs when interrupted just as they passed the bend test and were ready to be sauced. Forgetting the controllers odd four minute drill, we turned the temp down from 225° to the lowest "Smoke" setting to hold them briefly. Luckily we returned within a few minutes to rescue the ribs. The continuous pellet feed had goosed temps to 400°! A serious flaw that should be corrected.
You then simply select your desired temperature via the digital controls and relax, safe in the knowledge that the temperature will stay steady and there won't be any dreaded hot or cold spots. This consistence is achieved through the efficient temperature control system and automated auger. This ensures a deep smokey flavor is embedded in your meat every time.

Update 2/18/2018: I made another call to Pit Boss today to get more information about their Copperhead vertical smoker.  The phone was answered on the second ring by a man in Oregon. He was incredibly helpful and even went out to the warehouse and measured the grates for me.  It looks like if you can get past the automated system and reach a real person then these guys will take care of you.

Convection is achieved using a number of techniques. Air is fan forced into the grill and channeled throughout by our arched flame broiler. Our exhaust design allows air to circulate evenly along the length of the grill and to the top shelf. This combination allows us to achieve uniform heat throughout the unit whether your smoking at 170°F or cooking all the way up to 600° Fahrenheit.
