15.1.3 Pump outputs
Only one pump can be assigned to each sequence. However, each pump can be
controlled by max two sequences.

15.1.4 Control parameters (P-bands, integral action times)
For every configured sequence, a P-band (Xp), an integral action time (Tn) and a
derivative action time (Tv) can be set.
Integration action time Tn = 00:00: The controller operates in P- or PD mode.
Derivative action time Tv = 00:00: The controller operates in P- or PI mode.
For fast commissioning of the controller, we recommend the following:
 Set integral-action time Tn equal to the greatest time constant of the controlled
path
 Set the derivative action time Tv of the controller equal to the time constant of
the measuring sensor
