3.1 Setpoint pH: [ 7.20 ]
The setpoint sets the desired pH for the pool
water. When the setpoint is exceeded or under-
shot, the dosing pump is activated. The default
setting created by the manufacturer is for dosing
pH-Minus.
If you want to convert from pH-Minus to
pH-Plus dosing, please see section chapter
3.4 below.
Min. Alarm (↓): [ 6.80 ]
3.2
Lower alarm level which triggers an alarm if un-
dershot. The alarm appears in the display.
Max. Alarm (↑): [ 7.60 ]
3.3
Upper alarm value, which triggers an alarm if
exceeded. The alarm appears in the display.
p – band: [ -1.00 ]
3.4
You can use this function to define two basic
settings in the control unit:
Dosing direction for pH – value:
With a negative p - band [ -1.00 ] the dosing
pump is activated if the setpoint is exceeded.
This setting is used to apply pH – Minus che-
micals.
With a positive p – band [ 1.00 ] the dosing
pump is activated if the setpoint is undershot.
This setting is used to apply pH – Plus chemi-
cals.
Note: When changing between pH-Minus
and pH-Plus water treatment products, the
dosing pipe must be flushed with water and
the injection valves must be cleaned.
Regulation slope
The figure gives the p-band ie the regulation
slope. Usual values are –1.00/1.00 depending on
dosing direction.
Meaning: For a p – band of 1,00 the dosing
pump works at full performance when the mea-
sured value deviates from the setpoint by 1
pH. If the real measured value within the p-
band approaches the setpoint, the dosing per-
formance decreases proportionately. That is, if
the deviation is e.g.   pH the pump works
at only 50 % of maximum performance.
3.5 I-reset time: [ 0 sec ]
The default manufacturer's setting must not be
changed.
3.6 D-action time: [ 0 sec ]
The default manufacturer's setting must not be
changed.
3.7

Min. Output: [ 10 % ]

The control unit calculates the percentage dos-
ing performance of a given pump depending on
the deviation of the measuring of the setpoint.
A minimum output of e.g. 10 % means that all
calculated values < 10 % are automatically
raised to a minimum performance of 10 %. That
is, the control unit works with a base load for
small deviations.
3.8

Max. Output: [ 100 %]

The control unit calculates the percentage dos-
ing performance of a given pump depending on
the deviation of the measuring of the setpoint.
A maximum output of e.g. 80% means that all
calculated values > 80% are automatically re-
duced to a maximum performance of 80%. This
reduces the dosing pump performance.
