xx.x y.yy zz.z
where xx.x is the proportional correction constant
where y.yy is the integrated correction constant
where zz.z is the derivative correction constant
each value is selectable between 0.1÷99.9°C in steps of 0.1.
The setting is PID by default with the following parameters:
The display shows
kP kI kD
