I have no idea how you would set you D model to mimic what I do with and analog model.
In my #3, with chips in the fire box I crank the heat with the door open while I load the racks with meat. As soon as smoke is visible I cut the heat to 100 then close the smoker door. Most often I get smoke before I finish loading all the meat, five to eight minutes should be enough to get it started. Run the entire smoke at 100 with a jerky fan, you will be drying the meat not cooking it. After 3 hours open the smoker, flip the meat and rotate the shelves, add chips if necessary.
