5.1.9 Tuning the pump controller
The bypass valve controller must be tuned in order to have the
most suitable reaction time for your system.
1.
Go to Menu > Tuning .
2. Select the tuning method:
•
Manual tuning
• Auto tuning
3. If you have selected Manual tuning , enter the Proportional
gain (Kp) and Integral time (Ti) .
If you want a faster reaction, increase the gain and reduce the
integral time. If you want a slower reaction, reduce the gain and
increase the integral time.
4. If you have selected Auto tuning , enter the percentage of the
maximum speed for the pump bank that the controller should
use to start the auto tuning.
We recommend to start with 25 % of the maximum speed.

5.1.10 Tuning the bypass valve controller
The controller must be tuned in order to have the most suitable
reaction time for your system. You can either tune the controller
manually by choosing the gain (Kp) and integral time (Ti) yourself or
let the controller determine these values automatically, based on
the configuration of your system.
