PI-controller (control signal P = Low)
- Set the desired setpoint and set the control difference to zero in manual operation.
- Switch to automatic operation.
- Increase Kp slowly until the control loop tends to oscillate due to slight setpoint changes.
- Reduce Kp slightly until the oscillations disappear.
- Reduce Tn until the control loop tends to oscillate again.
- Increase Tn slightly until the tendency to oscillate disappears.

- Set the desired setpoint and set the control difference to zero in manual operation.
- Switch to automatic operation.
- Increase Kp slowly until the control loop tends to oscillate due to slight setpoint changes.
- Switch Tv from oFF to 1 s.
- Increase Tv until the oscillations disappear.
- Increase Kp slowly again until the oscillations reappear.
- Repeat the setting according to the previous two steps until the oscillations cannot be
eliminated again.
- Reduce Tv and Kp slightly until the oscillations stop.
- Reduce Tn until the control loop tends to oscillate again.
- Increase Tn slightly until the tendency to oscillate disappears
