Behmor 2000 AB Plus — reference
Operational reference for the Behmor 2000 AB Plus pulled from the official knowledge base — startup sequence, profiles, weight settings, safety features, and temperature readings.
Pulled from the Behmor knowledge base so it’s available on-hand during a roast. Cross-checked against the official 2000AB 120V manual (V28, Nov 2023) .
Profiles: P1–P5 are power levels, not programmes
This is the most important thing to understand about the Behmor. P1–P5 set the heating element power, not an automated roast curve.
| Profile | Power | Use | OK after FC? |
|---|---|---|---|
| P1 | 0% | Rotation with no heat. Use to stall or cool slowly without hitting C. | ✓ |
| P2 | 25% | Light drying phase or very slow finishing. | ✓ |
| P3 | 50% | Recommended post-FC setting. Drop to P3 at first crack and let exothermic momentum finish the roast. | ✓ |
| P4 | 75% | Pre-FC drying and Maillard phase only. ⚠ Not recommended after first crack. | ✗ |
| P5 | 100% | Early drying phase only. Drop to P3 at FC. ⚠ Not recommended after first crack — risks scorching beans and sensor damage. | ✗ |
The recommended roast approach (per official docs): Start on the automatic program (weight setting drives the default program time). At first crack, press P3 to drop to 50% power and let the beans’ own exothermic momentum carry development. Use C and D buttons to manage the final phase.
P4 and P5 should only be used in the early (drying/Maillard) phase, not during or after first crack.
Weight settings — default program times
The weight button only sets the program duration. Heat is controlled by the profile (P1–P5).
| Actual charge | Weight button | Program time | 75% shutoff at | Why |
|---|---|---|---|---|
| ¼ lb (≈113 g) | ¼ lb | 8:30 | 6:22 elapsed | Official beginner starting point. Manual says never start above ¼ lb until familiar with the machine. |
| ½ lb (≈227 g) | ½ lb | 12:00 | 9:00 elapsed | Standard batch. 75% shutoff at 9 min elapsed — may coincide with first crack. Stay close. |
| 1 lb (≈454 g) | 1 lb | 18:00 | 13:30 elapsed | Full batch. More thermal momentum — harder to stop development at the right moment. |
Match the weight button to your actual charge. The 75% safety shutoff fires at 75% of the program time selected.
Preheat sequence
- Weigh green beans into the drum. Keep the drum out of the machine.
- Select your weight setting and profile. Press START. Machine begins warming with no drum.
- Let run 1 minute 30 seconds. For ½ lb (12:00 program), the timer will read 10:30 remaining.
- Open the door and insert the loaded drum.
- The program continues from where it left off.
For back-to-back roasts, the chamber is already warm — skip the preheat and account for earlier FC on subsequent batches.
75% auto-safety shutoff (Err 7)
At 75% through the program, the display blinks and counts down from 0:30. Press START to continue. If you miss it, the machine enters cool mode and shows Err 7. This applies in both automatic and manual modes.
The exact “75% at” time is shown in the weight-settings table above. On a ½ lb batch it lands at 9:00 elapsed — potentially right in the middle of first crack — so stay near the machine.
A/B temperature buttons
- A button: exhaust channel temperature (available once the exhaust fan activates mid-roast)
- B button: chamber wall temperature
Neither reading is bean temperature. Use them as relative indicators of roast progress, not absolute targets.
Drum speed — D button
The D button adjusts drum rotation speed. Higher speed = more even tumbling, slightly lower peak surface temp. Lower speed = more surface contact heat. Adjust after FC to fine-tune development if needed.
C button (cool)
Pressing C before the program ends starts the cooling cycle immediately. Use this as your drop trigger — hit C at the moment you want to stop development.
Beginner guidance (from official docs)
- Start with ¼ lb batches on P1 for your first four roasts to learn the machine.
- Do not start above ¼ lb until you’re comfortable with timing and the shutoff.
- “The Behmor Roaster is not a set and walk away device — always stay by the roaster when it is in use.”
