Set the integration time for the control of the pressure at S10.
Low value:
Controller reacts fast, but with less stability
High value:
Controller reacts slow and with higher stability

Set the acceptable pressure deviation at S10.
When the actual pressure is within the neutral zone, the controller does
not change the refill pump speed.
Low value:
A low variation in pressure is acceptable
High value:
A high variation in pressure is acceptable
The neutral zone is symmetrical around the desired pressure value, i.e.
half the value is above and half the value is below this pressure.

The output voltage for controlling the speed of the refill pump can be limited
to a maximum value.
See also "V out min".
0 - 100:
The value in % expresses the maximum voltage
for controlling the analogue output for the speed
control of the refill pump.
Example:
A setting of 60 % means that the output voltage will be 6 volt as a
maximum.
The setting of "V.out min" has priority over "V.out max".
