Description
pH-
pH-reducing
pH-Minus
In the most cases, the pH value of the pool fill water lies above the
recommended range 7.0..7.4 pH, and the pool water generally tends to an
increase of the pH value. The standard dosing of the pH FUN is therefore
pH-reducing, with dosing of pH-Minus.
pH+
pH-
increasing
pH-Plus
In some cases the filling water or pool water tends to lower pH values. For
this, the dosing direction of the pH FUN can be switched over to pH+ (pH -
increasing). pH-Plus must then be dosed.
Danger warning:
The pH regulation of the pH FUN can only work correctly if the dosing direction is set correctly and
the appropriate pool care product is used.
For the dosing direction pH-, you must use pH-Minus as pool care product; for the dosing direction
pH+, you must use pH-Plus.
If this combination is not observed, an overdosing can occur despite the comprehensive safety
mechanisms of the pH FUN. In extreme cases, this can lead to health hazard.
Dosing alarm
The pH FUN checks at regularly specified time intervals whether the pH value of the pool water has sufficiently
approached the set setpoint. If this is not the case, there is probably a problem and the pH FUN blocks the dosing.
A dosing alarm is triggered.
You can set the time interval according to which the criteria for the dosing alarm are checked. The standard setting
of 60 minutes delivers good results in most cases.
If unnecessary or undesired dosing alarms occur or the dosing alarm does not activate as expected, the time
interval can be adapted accordingly (see Chapter 9.1 The pH FUN reports an alarm).
Danger warning:
By setting the time interval to 0 minutes, the dosing alarm is completely deactivated. Doing this will
override an important safety mechanism of the pH FUN.
With deactivated dosing alarm, under certain circumstances, an overdosing can occur which in the
extreme case can also lead to health hazard.
We therefore expressly advise you against deactivating the dosing alarm. The responsibility lies
with the operator for a deactivation of the alarm.

Initial operation of the pH FUN
The first time a factory-new pH FUN is switched on, a special initial operation menu is automatically run through which
will lead you step-by-step through the most important basic settings.
The menu tree in Chapter 4.2 The pH FUN menu will provide you with an overview of the initial operation menu.
Perform the parameter settings in the individual steps of the initial operation menu according to the general mechanism
as described in Chapter 4.1.2 Performing a parameter setting.
If the initial operation is not run through completely until it reaches the normal view, the initial operation will be started
again the next time the pH FUN is switched on.
The execution of the initial operation is described under 2 Putting into operation

The energy-saving mode of the pH FUN
After 15 minutes, the pH FUN will automatically switch to an energy-saving mode. The display illumination is switched
off in this mode. All measurement and control functions of the pH FUN are, however, active without restriction in the
energy-saving mode. The display illumination automatically switches on and blinks for alarms.
You can exit the energy-saving mode at any time by pressing any button.
