It is expected that control stability will change slightly as you change your batch size, flow rate, or heat input.
In general:
Faster flow rates reduce oscillation and overshoot
Lower heat input reduces oscillation and overshoot, but increases heating time
Higher heat rates increase overshoot and oscillation – shoot for 1.5F/min
Larger batch sizes generally exhibit less oscillation and overshoot
That said, doing small batches on a system intended for large batch sizes will usually be difficult to control. If
this is unavoidable, use the largest water to grist ratio possible, and use the lowest heat setting on your
burner, and be ready to accept control outside the +/- 0.5F band.
It is also expected that you will need to do a few experimental batches
to dial in your specific system and
become familiar with the operation and control of your system. You will quickly learn the flame height that
results in a 1.5 F/min average ramp rate in your mash bed. You will also discover what flow rates you can
achieve without sticking your mash. Note that rice hulls can aid in increasing recirculation rates.
