Each mode locks or unlocks specific controls. • During preheat, the machine targets drum temperature via IBTS (Infrared Bean Temperature Sensor). A standard preheat target is 230°C. Fan, drum speed and power are fixed by the roaster during preheat — they cannot be manually adjusted. • In roasting mode, heat (F1, scale 0–9), fan speed (F2, scale 1–9) and drum speed (F2 → D, scale 1–9) are all independently adjustable. For a 300g batch, power settings of 7–9 are considered very high. • The IBTS measures infrared drum/bean surface temperature. The bean probe measures contact temperature inside the drum. Both are displayed via the A button and serve different diagnostic purposes. • Back-to-back (B2B) roasting: after a roast, pressing F1 in cooling mode queues the next preheat cycle while the current batch still cools in the tray — no downtime between batches. • The A02 alarm activates when bean temperature exceeds 160°C and no control has been adjusted for more than 2 minutes. It is a mandatory operator-presence check. Pressing any button clears the alarm. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ABOUT ROAST REBELS Roast Rebels is Europe's leading retailer for small-scale coffee roasting machines, including the Aillio Bullet.
