7.7.3 Proportional gain Kp setting

7.7.4 Reset time Ti setting

In case of an error variable, the P portion immediately (i.e. without delay)
changes the position value proportionally to the error variable.
If a small error variables already requires a major valve position adjustment,
the proportional gain Kp must be increased.
