When the pH is above the upper set point, the pump will dose to the fixed volume
defined for the upper point. In the case of the figure, 90%.
You can set both points and choose the percentage of dosage for each of them. To
do this, press the cursor with the
MENU
key in the parameter you want to modify
and act with the arrows to change the value.
Press
OK
to save the data and exit the sub

menu.
By choosing the set points you will be defining at the same time the required dosing
volume and the response delay after dosing, both of them depending on the size of
your pool. For example, if your pool has a high volume you should establish high
percentages of dosing. The response time in the pH measurement of your pool can
be considered when setting point A of the setpoint, stopping the dosage before
reaching the desired pH value. For example, to obtain a pH = 7.0 and avoid
overdosing, set the dosage stop in a higher value:
A: pH 7.2 0%
Each pool needs more or less acid, as they are more or less reactive to the dosage,
at the beginning at least, you may need to correct the set points several times.
A: pH 7.0 10%
B: pH 9.0 90%
