This parameter is added to the %process output that is calculated at
the end of the PID according to process set value.
* / ( - )
Example If = 500°C , = 1000°C , = 0 , = 5.0%
then * / ( - ) = 5.0 * 500 /(1000-0) = 2.5%
2.5% is added to calculated process value.
(FOR HEATING PID 0.0%, 100.0%)
(FOR COOLING PID -100.0%, 0.0%)
This parameter is added to “Output %” which is calculated at the end of
the PID.
