Note for onboarding:
This chapter is for advanced users.
You can skip it during initial Brautomat setup and return later if needed.
Start first with AutoTune step by step and PID instructions.
Brautomat does not use simple on/off heating. It continuously adapts power and interval timing based on temperature behavior.
Benefits:
less manual correction during brew day
How adaptive logic works
During mashing, the controller continuously evaluates:
distance to target temperature
residual heat in the kettle
heater type (induction, relay, fermenter)
From these inputs, the controller continuously recalculates required power.
1. Fast heating phase
If target temperature is still far away, heating runs with high power to reach the next rest quickly.
2. Gentle approach to target
As target temperature gets closer, output is reduced automatically. This prevents overshoot.
3. Stable rest hold
At target, the controller keeps temperature stable with small, controlled output adjustments.
Ramping between 50°C and 78°C (approx. 1°C per minute)
Most important enzyme rests are in this range. Brautomat can limit ramp speed to around 1°C per minute for cleaner transitions and better repeatability.
Automatic interval adjustment
Besides output power, adaptive logic also adjusts control intervals.
When temperature is dynamic
(for example during heating, stirring, or adding water)
updates run more frequently
When temperature is stable
(for example during a rest)
Interval behavior during controlled ramping
Situation
Interval behavior
Temperature rises too fast
Intervals shorter -> earlier correction
Temperature rises too slow
Intervals shorter -> stronger correction
Temperature follows target cleanly
Intervals longer -> quiet operation
This creates a smooth and reproducible heating curve.
