Control action explanations 8.1 PID (1) Proportional band (P) Proportional action is the action during which the control output varies in proportion to the deviation between the SV and the PV (processing temperature). If the proportional band is narrowed, even if the output changes by a slight variation of the processing temperature, better control results can be obtained as the offset decreases.
