Manual dosing
The parameter specifies in litres the dose amount of a manual dosing. In addition, the pH FUN shows the duration
of the manual dosing (in minutes) which results from the respective dose amount (see also Chapter 5 Performing a
manual dosing).
Dose amount
Using the dose amount parameter, the amount of the pH-Minus (or pH-Plus) which the pH FUN doses into the pool
water can be varied.
In most cases, the standard setting "normal" delivers optimal results. Should the dosing achieved with this setting
be generally too high or too low, a corresponding correction can take place:
Setting
Description
normal
Standard setting
low
Dose amount is generally reduced by 30% compare d to the standard setting ("normal").
high
Dose amount is generally increased by 50% compared to the standard setting ("normal").
Min.dos.rate
With increasing proximity of the pool water pH value to the pH setpoint, the pH FUN automatically reduces the dose
rate, i.e. less and less pH-Minus (or pH-Plus) is dosed. However, this can lead to the setpoint not being reached
completely.
The minimum dosing rate of the pH FUN acts against this. It will never be fallen below as long as the setpoint was
not yet reached.
The standard setting should only then be modified when the pH value of the pool water either does not reach the
desired setpoint or overshoots the desired setpoint. (see also Chapter 9.3 The pH value in the pool is not correct)
pH setpoint
The parameter specifies the desired pH value in the pool water. A pH value in the rage of 7.0..7.4 is recommended
for swimming pool water.
pH alarm limits
Should the pH value of the pool water depart from the setpoint value due to a problem, the pH FUN triggers a
measurement alarm. The alarm values are set as range around the current setpoint e.g. 7.20 ± 0.4 pH. The setpoint
in this example lies at 7.2 pH, the lower alarm limit at 6.80 pH and the upper alarm limit at 7.60 pH.
Acoust. alarm
Activation or deactivation of the acoustic alarm of the pH FUN.
Language
You can switch the menu language of the pH FUN here.
Pool volume
You can enter the volume of your swimming pool in m³ (cubic metres) here. The pH FUN automatically adapts the
pH-Minus (or pH-Plus) dose amount to the entered pool volume (see also Chapter 7.2 Calculating the dosing rate).
Important:
The pool volume must absolutely be entered correctly to ensure an optimal dosing and thus a
proper control of the pH value by the pH FUN.
Furthermore, there is the possibility, where necessary, to increase the dosing amount by input of a
larger pool volume or to reduce the dosing amount by input of a smaller pool volume.
