    11. Control action explanation 11.1 P, I, D and ARW (1) Proportional band (P) Proportional action is the action which the control output varies in proportion to the deviation between the setting value and the 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.
