I just installed a new controller on an older grill and no longer see the hole where the P Setting was previously modified...is the P Setting no longer a thing?On supersmoke the D2 controller will cycle with emphasis on smoke quality. Since the fan and auger are variable the control should be tighter. So it's a choice in most cases.
On the older more simplified logic, (Pro Controller) the auger will feed pellets for 15 seconds. A user adjustable delay or P setting will vary the time between auger rotation cycles. This is set based on your seasonal ambient temperature. This was handy for us in the frozen tundra
