SC

PV Bias

The value set in the PV bias is added to the actual input value to correct the input value.

Set when PI or PID control is performance. For heating / cooling PID action.
When P=0,the controller is ON/OFF control

 I

Calculus time

Eliminates offset occurring in proportional control.

 d

Differential time

Prevents overshoot and/or undershoot caused by integral action effect..
