Pre-heat Gene and let rumble around at 350* till unit is warm. Then hold button down till E stop occurs.
Dump beans in and turn to:
471* for low grown
474* for Brazils, Sumatrans
476* for high growns: CAmer, African, Yemens
Run at those temps. At 1:00 after first crack, turn down 3-4.* Then, play with profiles, ending 2:30, 2:45 and 3:00 minutes past the start of 1st crack. See which works better for which bean.
You are putting too much energy into the bean with 482.* Tom at SM's suggests 482* throughout the entire roast. I couldn't disagree more. Nuances will be driven out of the bean, or so my experience tells me. Experiment and see how it works for you.

B|Java, still use the same profiles?
No, those came from my first unit which delivered less heat at the same reported temp than the unit I am using now.
I use these in the new unit (I believe the manufacturer improved the heater at some point):
455* for low grown, Kona/Caribbean
458* for Brazils, Sumatrans
460* for high growns: CAmer, African, Yemens
