If cooling function and PID control form is selected for the system;
If set value is less than process value, process output becomes active till to the
Temperature - [(Temperature-Set) / 2] value. When process value reaches to this
value, process output is reduced to 0% and it calculates PID coefficients.

For Self Tune ( Step Response Tuning ) operation :
1 - Tune selection parameter in “run List” menu must be selected Self tune
or Auto-Self Tune
2 - For Self Tune ( Step Response Tuning ) operation, firstly power off and then
apply power to the device.
3 - For being started Tune operation (Auto Tune or Self Tune) control form must be P,
PI, PD or PID.
4 - If process set value is changed while Tune operation is being performed, Tune
operation is canceled.
