1. Usage of four parameters: Proportion parameter (Kp), integral parameter (Ki), differential
parameter (Kd), control proportion band (Diff)

Parameter P is the proportion parameter.

Parameter I is the integral parameter.

Parameter D is differential parameter

Temperature Control Band Means: in the assigned band, to carry out PID control.
PID Temperature Control Curve is Shown Below:
Note:
Each parameter’s reference value: Kp=20/100, Ki=5/20, Kd=200~500, DIFF=100/200.
This reference value only for normal condition, according to the locale detail condition, each
reference value could be beyond the band.
When using PID, the BD board will perform heating control with a cycle of 2 Seconds.
This modifies the output value based on the PID control.
