The proportional band defines within which change of the control variable

∆x (∆T of the

flow) the whole correcting span y (valve travel) is traversed.
The smaller the proportional band, the greater the change of the manipulated variable
∆y at a given change of the controlled variable ∆x.

The integral action time is the period of time the controller’s I-part would require to
produce the same change of the manipulated variable as the P-part
