The Automatic Temperature Control uses a PID Control Algorithm and a Pilot Control to achieve the desired grill temperature.
The standard Values should be a good starting point and work decently for most Grills.
The Control output of the BBQ Ctrl is calculated as Output = PC + KP * ΔT + ∫KI*ΔT + KD*ΔT/dt
PC - Pilot Control, set to the value of the BBQ Ctrl Output when the Temperature has settled to 120°C
KP - Proportional factor, will decrease response time, but can lead to instabilities.
KI - Integral Factor, will decrease long term offset. High values can lead to instabilities
KD - Differential factor. Looks at the trend of the Temperature and adjusts the output. Dampens oscilations, too high values can increase oscilations
Bangang Range - Range around the Target Temperature at which the output is set to 0 or 100% respectively
Maximum Servo Angle is automatically selected with the Barbecue Model and can not be changed.
