Last night we smoked some chicken legs. Smoked 2 hours on "smoke", and then put it to 250F until the internal temperature hit 265F.
However, we noticed that during the cooking that the auger was following the on/off cycle as shown in the table for the P4 setting. On for 18 seconds, off for 115 seconds. This suggested that the P settings are used even when not turned to "smoke". (I did not test it by setting to a different P setting and then pulling out the stopwatch)
However, this causes some confusion. The fan speed didn't change at all during the cook. If the P setting was controlling the pellet drop, and the fan wasn't changing speeds, how was it controlling the temperature? The only variable remaining is the igniter, but I cannot imagine that they use the igniter to change the temperature.
Thoughts?
