I have an older 3 D and cook only to temp or time. No other programming or pre-sets and ramps etc. I zero out what I do not use. Also, I have the instructions at the smoker each time I use it. Sad but as with vcrs and our cable box, I do not find digital gadgets intuitive. Wish I could help. And the instructions are not as simple as they could be. Screen shots and arrows and text all add up to confusion on my end.
