1. Introduction
WDPHCL is a fully Integrated All-in-One Swimming Pool Controller. Ideal for new construction projects the WDPHCL
innovates panel mount capability into a small wall-mount package.
2 Pumps for Chlorine and pH adjustment in PVDF, small-form-factor saves space, installation time, and shipping
expense.
It includes Input for a Flow Switch. Integral pumps can handle up to 20 bar and 16 l/h (Self-Venting Liquid-end as option),
high maintenance tubing sets and roller assemblies.
Working ranges are:
pH : from 0 to 14pH
Chlorine: from 0 to 10 mg/l
All information are provided through a large LCD display. Using a revolutionary wheel control the instrument can be easily
programmed. WDPHCL is housed in a IP65 plastic box.

Do you know ?
In chemistry, an alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Alkalis are best known for
being bases (compounds with pH greater than 7) that dissolve in water. The adjective alkaline is commonly used in English
as a synonym for base, especially for soluble bases. This broad use of the term is likely to have come about because
alkalis were the first bases known to obey the Arrhenius definition of a base and are still among the more common bases.
Since Brønsted-Lowry acid-base theory, the term alkali in chemistry is normally restricted to those salts containing alkali
and alkaline earth metal elements.
An acid (often represented by the generic formula HA [H+A−]) is traditionally considered any chemical compound that,
when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water, i.e. a pH less than 7.0.
That approximates the modern definition of Johannes Nicolaus Brønsted and Martin Lowry, who independently defined an
acid as a compound which donates a hydrogen ion (H+) to another compound (called a base). Common examples include
acetic acid (in vinegar) and sulfuric acid (used in car batteries). Acid/base systems are different from redox reactions in
that there is no change in oxidation state.

8.1 “Set-Point”, pH (proportional)
pH reading values can be set to operate the pH pump using 2 set-points into On/Off mode or Proportional (%).
Proportional mode set the instrument to operate using a calculated percentage between two set values that
enable or disable the pH pump. To use this mode move cursor on “Working Mode”. Press the wheel and select it.
PROPORTIONAL mode between 7pH(0%) and 8pH (100%). [Stroke setting 180]
In this mode the pH pump will be “ON” for values greater than 8pH with maximum set strokes capacity (e.g.: 180) and
it’ll be “OFF” for values lower than 7pH. For values of 7.5pH pump will be “ON” with 90 strokes capacity. The calculation
is based on 180 strokes setting (see page 22). To end procedure move cursor on “OK” and press wheel to proceed to
“Save” request screen. Move wheel on “YES” to save or “NO” to discard changes.

15
8.2 “Set-Point”, Cl (on/off)
Cl reading values can be set to operate the Chlorine pump using 2 set-points into On/Off mode or Proportional (%).
On/Off mode set the instrument to operate using two set values that enable or disable the Chlorine pump. To
use this mode move cursor on “Working Mode”. Press the wheel and select it.
ON/OFF mode
Set Cl value at 0.80 mg/l ON and 1.00 mg/l OFF. The difference between the two Cl values is called HYSTERESIS.
Instrument will enable the Chlorine pump when reading value will decrease at 0.80mg/l
At 0.80mg/l the Chlorine pump will be enabled until reading value will increase at 1.00mg/l.
Waiting Time: to let pump operate at pulses per minutes add one or more minute (1pulse every xx minutes). Otherwise (00 minutes) pump will
operate at set stroke settings (see page 22).

8.3 “Set-Point”, Cl (proportional)
Cl reading values can be set to operate the pH pump using 2 set-points into On/Off mode or Proportional (%).
Proportional mode set the instrument to operate using a calculated percentage between two set values that
enable or disable the Chlorine pump. To use this mode move cursor on “Working Mode”. Press the wheel and
select it.
PROPORTIONAL mode between 1.00Cl (0%) and 0.50Cl(100%). [Stroke setting 180]
In this mode the Cl pump will be “ON” for values lower than 0.50mg/l with maximum set strokes capacity (e.g.: 180)
and it’ll be “OFF” for values greater than 1mg/l. For values of 0.75mg/l pump will be “ON” with 90 strokes capacity. The
calculation is based on 180 strokes setting (see page 22). To end procedure move cursor on “OK” and press wheel to
proceed to “Save” request screen. Move wheel on “YES” to save or “NO” to discard changes.

9. “Probe Calibration”, pH
pH calibration procedure involves two calibration points and it requires two buffer solutions. Default buffer solutions are
pH 4.00 and pH 7.00. pH reading value can be also 30°C temperature compensated from “pH compensation” menu.
From “Menu Calibration” choose “pH probe”.
In the following example instrument will calibrate pH using default buffer solutions values.
Note: this procedure assumes that instrument is correctly configured and a working pH probe connected.
Otherwise unattended results may occurr.
Calib 1st Point.
Once into “pH Calibration” menu move wheel on “P1” then press wheel to enter into first point calibration submenu.
Prepare 7.00pH buffer solution and dip probe’s sensor on it. Wait until reading value is stable and according to buffer
solution value move wheel until it is the same on display (“Cal. at” field). Default value is 7.00pH. To end procedure
move cursor on “OK” and press wheel to proceed to next step.
Note: buffer solution value may change if environment temperature it’s different than 20°C. Read solution’s
label for more information.According to this occurrence “pH Default” must be changed.
pH7
Power Supply calibration ?
To obtain the most reliable results during pulses calculation is possible to calibrate power supply read value. Press wheel on “P1” then move curso on “OK” and
confirm power supply read value. (e.g.: 230V).

18
9. “Probe Calibration”, pH
Calib 2nd Point.
Move wheel on “P2” then press wheel to enter into second point calibration submenu. Prepare 4.00pH buffer solution
and dip probe’s sensor on it. Wait until reading value is stable and according to buffer solution value move wheel until it
is the same on display (“Cal. at” field). Default value is 4.00pH.
To end procedure move cursor on “OK” and press wheel to proceed to “Save” request screen. Move wheel on “YES” to
save or “NO” to discard changes.
Note: buffer solution value may change if environment temperature it’s different than 20°C. Read solution’s
label for more information.According to this occurrence “pH Default” must be changed.

9.1 “Probe Calibration”, Cl
Cl calibration procedure involves probe’s selection, Zero (P1) and 2nd Point (P2) calibration. From “Menu Calibration”
choose “Cl probe”.
Note: This procedure assumes that instrument is correctly configured and a working Chlorine probe connected
and installed on system. Measurement must be performed using plant water. Otherwise unattended results
may occurr.
Calib Zero (P1).
Once into “Cl calibration” menu move on “P1” then press wheel to enter into
calibration mode. For a correct system calibration proceed as follows.
- install an “activated carbon filter” prior to probe’s holder.
- let system water flow into probe holder for about 30 minutes.
- press wheel (cursor must be on “Cal.at”). Remove filter.
Calib 2nd point (P2).
Now move on “P2” then press wheel to enter into calibration mode. For a correct system calibration use a Photometer
or a DPD device to read chlorine on system. Enter value using the wheel then move cursor on “OK”. Now press the
wheel.
Carbon Filter System
Photometer
To end procedure move cursor on “OK” and press wheel to proceed to “Save” request
screen. Move wheel on “YES” to save or “NO” to discard changes. If an error occurred
during calibration procedure then the instrument will show an error message and will ask
to proceed to a new calibration, cancel current operation or restore default settings.

10. “Parameters”
From “Menu Calibration” choose “Parameters”. This menu allows to set a delay (max 60 minutes) before pumps begin
to feed. Furthermore use this menu to set pH pump startup priority and to change default passcode.
Feeding Delay.
Move on “Feeding Delay” then press wheel. Choose a value between 0 (disabled) and 60 minutes (maximum delay
time). This feature can be used to accord a startup delay for the pumps. Delay occurs when instrument is powered or
after a “NO FLOW” contact recovery.
Mode.
Move on “Mode” then press wheel. If both pumps need to operate, a startup priority can be set to allow the pH pump to
begin to feed prior to Cl pump. Choose “pH priority” to enable this function. Cl pump will begin to dose when pH pump
has stopped.
New Pcode.
See page 10.
To end procedure move cursor on “OK” and press wheel to proceed to “Save” request screen. Move wheel on “YES” to
save or “NO” to discard changes.
