Auto Tuning:-
The Auto-tuning function automatically computes
and sets the Proportional band (Pb) , Integral time (It),
Derivative time (dt), and cycle time as per process
characteristics.
Tuning LED will turn "ON" during Auto-Tuning
If the power goes off before auto-tuning is completed,
auto-tuning will be restarted at next power ON.
