Answer / ashok prajapat

first of all it is important that how much level u want to
control in boiler for exp. if u want to set level 50 % in
boiler then first of all set only p value n pid controller and
this time keep i and d at zero and see process value.now slowly
increasethe value of I and then see again process value and
finally set d value if required.for exp range of these values
may be;
P: 0-100
I: 0-20000
D: 0-100
