Divy, Play around and explore the Behmor as it seems each unit is slightly different, based on voltage at your powerpoint. Suggest if you are electrical savy or have a sparkie friend, measure the voltage of your power point so you can best adapt the unit to it - its all in the set up when you read the instructions. Programs, again have a play - I have explored and suggest a bean mass of 250g to 300g, I have settled on 300g lately as suggested by RM as the consistency is much better at this volume. I always use 1Ib setting regardless and P2B, P2C or even P3C. P2B will bring you into a roast time of around 17min or so. I dont have a probe at all in the unit but do a prewarm on P1 for a couple of minutes without drum and then using gloves kick the unit off. So I suggest start with 300g, 1IbP2B with a prewarm and with Elephant Hills or Peru CDS you cannot go wrong - just keep yourself some notes as you go - simple things like settings, weights, 1st crack, rolling 1st crack, 2nd crack and pull time. Enjoy the experience! Jonty Edit (PS): Make yourself an external bean cooler - that way you can dump them quickly and cool ultra quick!
