The above values are optimally set for the actuator as default settings. They can be changed if required for
the following conditions:
The P band is to be increased in case the PV (process value/ valve position) increases the SV (set valve)
and the actuators goes into hunting between Open and close and settles at the SV (set value).
Duty Cycle will depend on the P band. P band & Duty cycle are proportional i.e. larger the P band larger
will be Duty Cycle.
H band (Hysteresis band) is to be increased in case there is continuous hunting and the actuator does
not stop.
