Dosing direction

As already described in the Water maintenance section, the pH control
system can be optionally run in a pH-reducing, pH-elevating, or bi-
directional manner depending on water composition.
The following image shows an example for control system output in
the event of bi-directional dosage.
1 dosing output in %
2 Measured pH value
3 Configured setpoint pH 7.20
4 pH measured value is higher than setpoint
pH minus dosage
5 pH measured value is lower than setpoint
pH plus dosage
6 dosing rate for various proportional ranges

11.4.10 Recommended settings

The following table provides information on the recommended
parameter settings for pH and redox control.

dosing applications and should only be changed in exceptional

applications.
For very small pools, e.g. whirlpools, it may be sensible to
reduce to 30s.

Basics

Sensible configuration of the proportional range and the minimum
dosing rate is largely dependent upon pool volume and dosage pump
output. In the end, what counts is the ratio between pool volume and
the pumps' dosing output.
The values used as the foundation for the default settings are:
Assuming a typical pool volume of 40 m
•
dosing output on standard pump 1.5 l/h
•
The assumed ration between pool volume in [m³] and dosing
•
output in [l/h] is therefore 40 to 1.5, i.e. ca. 27.
For a larger pool volume in relation to dosing output, the control
parameters generally have to be adjusted as follows:
Smaller proportional range (
•
Higher minimum dosing rate
•
Accordingly, for a smaller pool volume in relation to dosing output the
control parameters generally have to be adjusted as follows:
Larger proportional range (
•
Lower minimum dosing rate
•
