3Important facts about swimming pool water properties
3.1 Auxiliary hygiene parameters
The following information is meant to offer a preliminary overview about the most important auxiliary hygiene parameters in the
treatment of swimming pool water. Additional literature is available from your swimming pool dealer, the chemicals suppliers, or
the book trade. The information provided here refers to DIN EN 16713 for swimming pool water in private pools. (applicable as of
08/2016)
Devices that are operated outside of the EU should comply with the county-specific regulations and statutes.
3.2 pH value
The pH value has a decisive effect on the chemicals added to the swimming pool cycle. If the pH value is too high, it negatively
affects the germ-killing speed of disinfectants containing chlorine. There is an increased likelihood of lime precipitation and water
clouding. If the pH value drops too low for an extended period of time, leading to an increase in the water's corrosivity, there is a
risk of damage to the treatment system and the pool.
According to the standard, values below pH6.8 and above pH7.6 should be avoided. A pH value around pH7 is recommended.
3.3 Redox voltage
The redox voltage is used as a measure for assessing the hygienic pool water quality. The redox voltage indicates the ratio between
reducing substances (organic contaminations) and oxidising power (active chlorine content) in the pool water. The redox voltage is
used as a measure for assessing the hygienic pool water quality. The higher the redox voltage, the faster germs and bacteria will be
killed. To achieve a sufficiently fast germicidal effect, the redox voltage in private pools should also comply with the values
specified by the DIN (German institute for standardization). In this context, the amount of free chlorine measured with the DPD1
method should be between 0.3 and 0.6 mg/l.
The chlorine’s disinfecting power essentially depends on the pool water’s pH value. The higher the pH value, the lower the
disinfecting power and thus the redox voltage. If the pH value decreases, the disinfecting power increases at a constant chlorine
level.
If the redox voltage is far below 700 mV at a free chlorine content between 0.3 and 0.6 mg/l, the complete function of the
swimming pool water treatment must be checked.
According to the standard, a redox voltage above 650 mV should be aimed for. Values below 650 and above 800 mV should be
avoided. A redox voltage around > 700 to 750 mV is recommended.
(According to DIN 19643 for public pools, a redox voltage > 750 mV is required.)
3.4 free chlorine
The chlorine available for disinfection in the pool water is called free chlorine. Free chlorine is detected by means of the DPD1
method.
According to the standard, the free chlorine content should be kept between 0.3 and 1.5 mg/l.
Values below 0.2 and above 2.0 mg/l should be avoided.
3.5 combined chlorine
Combined chlorine is the product of a reaction between organic contaminants introduced in the pool and a chlorine-containing
disinfectant. Combined chlorine causes the characteristic indoor pool smell and may lead to skin irritation and red eyes.
Ideally, the organic chlorine compounds will be retained in the swimming pool filter system and flushed out via the regular
backwashing. If the filter system does not work correctly, or if the backwashing is not conducted in a proper fashion, combined
chlorine may accumulate in the swimming pool cycle. If the water starts smelling of chlorine, it is high time to conduct a chlorine
measurement by means of the DPD3 measuring.
The concentration of combined chlorine results from the difference between the overall chlorine content and the amount of free
chlorine in the water. Pay attention to the instructions of the analytic device's manufacturer when determining the concentration.
Combined chlorine can only be reduced by dilution, i.e., with vigorous backwashing or by a shock chlorination, if applicable.
Consult your swimming pool dealer.
According to the standard, a maximum combined chlorine content of 0.5 mg/l is permissible.
“Chlorine odours” can result above a combined chlorine content of approx. 0.3 to 0.4 mg/l. (characteristic indoor pool smell)
Tip –pH priority dosing
Since the pH value is an elementary factor in the swimming pool water treatment, the dosing of chlorine-containing
disinfectants can be blocked via the pH stop dosCL function, depending on the pH.

The POOLKLAR Touch Basic is delivered as a ready-assembled unit. All parts are mounted on a plastic plate. This ensures a quick
installation of the device.
For the transport, the electrodes 3+4 are removed from the measuring cell and delivered separately in a protective packing box. In
order to avoid deformation of the dosing hoses during extended storage, the two dosing heads 11 have been pulled off the motor
shaft.
The POOLKLAR Touch Basic is equipped with a touch-sensitive touch screen. This function is activated by touching a symbol (ICON).
The calibration menus come with additional text-based instructions.
In order to eliminate the risk of confusing the two chemicals as far as possible, the dosing technology is colour-coded throughout.
The colour-coding extends from the suction set over the associated dosing pump to the dosing valve.
The parts used for pH value regulation are located to the left and coded in red. The components used for disinfection are located
on the right and coded in yellow.
CAUTION!
If the two chemicals are switched, this leads to a malfunction of the addition of chemicals to the pool water! This
may result in significant overdosing!

5Installation
5.1 Select the installation site
A freely accessible installation site should be selected to facilitate operation and subsequent maintenance tasks. The installation
site must be protected from frost and the device may not be exposed to direct sunlight.
5.2 Mounting the device on the wall
Select the installation height so that the display is located at eye level. Measure the three drill holes on the mounting plate and
mark their location on the wall.
5.3 Voltage supply
The devices' voltage supply (230 VAC) can be realised in two ways.
1. Continuous voltage:
This variant has advantages when there is a risk of condensation moisture, e.g., in a technical shaft at the head of the
pool outdoors.
2. Voltage supply parallel to the filter pump
This variant can be selected for dry installation rooms. The advantage then lies in the reduced operating hours of the
electronics.
In addition, the devices are equipped with an external OFF release contact. The dosing can be temporarily deactivated via this
contact, which is interlocked with the filter control.
5.4 Installation notices
Only good pool hydraulics can achieve a satisfactory control of the two auxiliary hygiene parameters, pH value and redox voltage.
The dosed chemicals must reach all areas of the pool within a short time. Even under stress, the concentrations measured at
different points must be approximately the same. The measuring water should be identical to the pool water and must reach the
measuring cell as quickly as possible. This is the only way to quickly detect changes in the water quality and rebalance them by
adding corrective chemicals.
If the pool water is conducted through an overflow gutter and a compensation pool (splash water), which is potentially also used
for the freshwater feed-in, only the sampling of the measuring water directly from the pool will lead to satisfactory measuring and
control results.
At very low temperatures <5°C, the touch screen may become impaired due to the stiffness of the frontal film!
5.5 Measuring water prefilter
Depending on the local conditions, it may be necessary to provide a prefilter in the measuring water supply line. Especially in
outdoor swimming pools, a higher amount of contaminants can be expected due to leaves, grass, flying seeds, etc.
Select an easily accessible installation site that allows the operator to easily recognise the degree of contamination.
5.6 Temperature sensor
A temperature sensor is included with the accessories. Due to the rather sluggish temperature changes in a swimming pool cycle,
this sensor can be attached to the filter circuit pipework as a contact sensor. If the temperature measurement is also used for
temperature control, or if a more precise measurement result is required, the use of an immersion sleeve is recommended.

WDT POOLKLAR Touch Basic
English translation of the original German version of the operation manual - Version 1.1 (HW CB36 –FW V1.0.0) 2021_07_09 9/38
5.7 Installation suggestion
The following sketch shows an example of the integration of the POOLKLAR Touch Basic in the swimming pool’s water treatment
cycle with a skimmer. As a rule, the measuring water is withdrawn between the filter pump and the filter tank ①. The water is
recirculated into the clean water line downstream of the heat exchanger ②. Two ball valves ½” with immersion pipe for the
connection to the filter piping are provided with the accessories. The immersion pipe of the two ball valves should be shortened so
that it ends approximately in the middle of the pipe.
In the case of an overflow basin, this variant can lead to greater measured value deviations. In this case, the measuring water must
be taken directly from the pool with an additional measuring water pump, dashed line ③.
In the case of an outdoor pool, a prefilter must be provided due to the expected higher contaminant load! ④
ATTENTION!
Since both chemicals are mixed in with the measuring water, the measuring water recirculation must occur in the
direction of the flow downstream of the heat exchanger in order to prevent corrosion.
If the pool is being operated with an overflow gutter and a splash water tank into which freshwater is also allowed
to enter, marked differences in the water quality on the measuring cell and in the pool can be expected. In order to
ensure perfect control quality in this case, it is recommended that the measuring water is withdrawn directly from
the pool, using a separate measuring water pump.
ATTENTION!
During automatic fresh water replenishment, the measured values can change considerably due to the addition of
fresh water. For this reason, we recommend interlocking the release of the dosing with the fresh water
replenishment to avoid overdosing. For this purpose, the controller provides the external OFF release contact.

6Notices regarding commissioning and ongoing operation
Before the device can be commissioned, the following actions must be implemented. You can find the position of the parts listed
in the following under Item 4.4 Device description.
6.1 Control parameters
The device is loaded with factory-defined control parameters; see Commissioning protocol. Please adjust the control parameters
for your pool according to the required dosing performance and the desired setpoints. The factory setting for the dosing
performance is 100%, which should be sufficient for an outdoor pool of approx. 100 m³.
6.2 pH and redox electrode
Remove the pH and redox electrode from the packing box and pull off the protective cap. Insert the two electrodes from above
into the flow-through fitting and fix them hand-tight with the union nut.
ATTENTION!
The two electrode cables must not be interchanged!
Original WDT electrode heads have colour differences; pay attention to the colour affiliation.
Black union nut on black electrode plug head (pH electrode)
Blue union nut on blue electrode plug head (redox electrode)
Tip
Following a temperature adjustment and inflow time of approx. one hour, the electrodes must be calibrated.
Tip
Keep the electrodes’ protective caps for later decommissioning or overwintering.
ATTENTION!
Please ensure that all hose screw connections of the measuring water pipes are firmly tightened. Check all pipe
unions at the device and at the two measuring water ball valves ½”. Plastic pipe unions may only be fastened hand-
tight!
6.3 Dosing head(s)
Push the dosing head(s) onto the motor shaft.
6.4 Measuring cell flow
Once all electrodes have been screwed hand-tight into the measuring cell and the measuring water pipes have been connected,
the ball valves for the measuring water withdrawal and recirculation may be opened. The flow meter float must be pushed toward
the top in order to release the dosing.
6.5 Chemicals
Place the two chemical containers under the device. In order to protect the floor, it is recommended to place the containers in a
protection tray. Please observe the proper positioning of the container; on the left red pH value correction chemical, and on
the right oyellow disinfection chemical.
ATTENTION!
Please do not use hydrochloric acid for the pH value regulation. Hydrochloric acid diffuses through the dosing hose
and corrodes the dosing motor, causing premature wear of the dosing pump.

WDT POOLKLAR Touch Basic
English translation of the original German version of the operation manual - Version 1.1 (HW CB36 –FW V1.0.0) 2021_07_09 11/38
6.6 Disinfectants
Notice
Please find out which chemical was used to disinfect the pool water prior to the commissioning.
If a different disinfectant is used from now on, the following must be observed.
If other disinfectants (e.g., organic chlorine (dichlorine) or “chlorine-free” disinfection chemicals) were used previously, this will
lead to a lower redox voltage during commissioning. Without changes to the control parameters, this results in significant
overdosing. The breakdown of the disruptive chemicals can take several weeks.
That means, if other disinfection chemicals were used prior to the installation of the POOLKLAR for the dosing of inorganic
chlorine, we recommend to run the device with removed dosing heads for about 0.5-1 hour to be able to observe the redox status.
The setpoint of the redox voltage should then be set at approx. 20-50 mV above the displayed value. The development of the
chlorine concentration and the redox voltage must be observed during the subsequent period, and the redox voltage’s setpoint
must be adjusted so that the measured chlorine concentration approximates 0.5 mg/l.
Under certain circumstances, only a sufficient exchange of the pool water will help.
6.7 Fresh water replenishment
An automated fresh water replenishment usually takes place into the skimmer or the splash water tank. If the measuring water is
now withdrawn downstream of the filter pump, a mixture of pool water and fresh water is fed to the POOLKLAR Touch Basic. The
resulting change in water quality can lead to excessive dosing.
To avoid overdosing, we recommend interlocking the dosing via the External OFF release contact.
6.8 Floor cleaning
Necessary floor cleaning can be carried out using different cleaning equipment. For this purpose, manual, hydraulic and automatic
electric cleaners are available on the market.
If floor cleaning is carried out by suction via the filter system, the measuring water line must be shut off.
The shut-off can be done manually at the ball valves or automatically via a solenoid valve.
Notice
If the measuring water is withdrawn downstream of the filter pump, floor cleaning via the filter system will result in a
higher contaminant load in the measuring water inlet. As a result, the measuring water prefilter can become clogged,
which leads to a reduced flow and the flow switch fault.
Moreover, a contaminated prefilter can be subject to a certain chlorine depletion, which leads to measuring value
falsifications and thus to overdosing.

ATTENTION!
The measuring amplifier may only be plugged in when it is disconnected from the power supply!
Non-compliance can lead to the destruction of the measurement converter or the I/O board!
7.4 External functions
7.4.1 Input External OFF –release contact
The external OFF input is used for the controlled deactivation of the POOLKLAR Touch Basic via the swimming pool filter system’s
central control. As long as the contact is open, there is no dosing, no heating of the pool water, no alarm message given.
7.4.2 Temperature control
The device is equipped with a temperature control. This temperature control can be used to regulate the pool water temperature.
If the pool is heated by means of a flow-through heat exchanger, it must be ensured that the associated heating circuit pump may
only be activated when the filter system is in operation!
Please remember that the regulation of the pool temperature can only be guaranteed if the filter operation times are set to an
appropriate duration.
In order to achieve a precise measuring result, the sensor must be installed by means of an immersion sleeve in the swimming
pool’s piping.
ATTENTION!
Immersion sleeves must be corrosion-proof!
ATTENTION!
Please pay attention to the safety notices regarding the topic of temperature control in the menu!

8.1 The statuses in automatic mode
Depending on the operating state, the display shows different status displays, which are described below.
8.1.1 Status 1. Dosing –dosing delay
If the device is restarted or if the main menu is terminated, the dosing delay 1.
Dosing in x s is running. No dosing occurs during the dosing delay.
Software alarms are suppressed during this time.
The dosing delay must be set high enough to ensure that after the start of the
filter system actual pool water flows through the measuring cell.
The dosing delay can be cancelled with and the device is set to automatic
mode.
8.1.2 Status pH stop dosCL –pH priority dosing
After refilling with fresh water, the pH value is usually above the recommended
pH values of 7.0 to 7.4
Due to the reduced effectiveness of chlorine-containing disinfectants at high pH
values, the release of the disinfectant dosage can be blocked depending on the pH
value to avoid overdosing.
The status line reads pH stop dosCL, the disinfection output is blocked.
8.1.3 Status Auto (automatic)
The device is in the status Auto (Automatic mode).
The auxiliary hygiene parameters and the temperature (optional) are regulated
based on set parameters.
IN: There is no fault
OUT: The temperature output is activated
8.1.4 Status standby
If Standby is displayed in the status line, dosing is blocked.
Either the controller is blocked by the filter system via the external OFF release
contact or the flow switch measuring cell flow is too low.
External OFF is an intentional action, no alarm is issued.
For the flow switch fault there are two possible causes. Either the filter system is
switched off or the flow through measuring cells is blocked, e.g., by contamination
in the prefilter.

8.1.5 Time Limit - Dosing time monitoring alarm
The controller is equipped with an intelligent, dynamic dosing time monitoring.
If the corresponding measuring value does not reach the control range within the
selected Time Limit time, e.g., due to a malfunction, the dosing stops with an
alarm.
A is shown in the IN list, the alarm relay is activated and the dosing stops.
This alarm is automatically reset by reaching the control range, by a device restart
or a manual acknowledgement by pressing the MENU key.
The cause is usually a worn dosing head or a blocked dosing valve. The Set Output
dosing performance may be set too low.
8.1.6 General alarm
If a fault or an alarm occurs, this will be indicated by a symbol in the OUT line.
The alarm relay is activated.
A differentiation is made between alarms (software alarms, e.g., alarm high, alarm
low) and faults (chemical container empty, measuring cell flow too low).
In the event of alarms, the respective measuring value is shown in red.
In the event of faults, the corresponding symbol appears in the In line.
Tip
An alarm is automatically cancelled when the cause has been eliminated, e.g., when an empty chemical container has
been replaced by a full container or when sufficient measuring water is flowing through the measuring cell again.
8.1.7 Temperature fault
If - - - - is displayed instead of a number for the temperature, there is a fault in
the temperature measurement.
This may be caused by the following:
1. No temperature sensor connected (cable broken)
2. Defective temperature sensor; (resistance too high > 1.35 kΩ)
3. Wrong sensor type(resistance too high 1.35 kΩ)
8.1.8 Measuring amplifier fault
If - - - - is displayed instead of the two measuring values pH and mV, there is a
fault at the measuring amplifier.
This may be caused by the following:
1. No measuring amplifier plugged in
2. Polarity of the measuring amplifier incorrect (22-pin header correct?)
3. Measuring amplifier defective
