Operating modes pH value
![]() | Auto The Automatic pH automatically doses pH-Minus Liquid Domestic (or pH-Plus Liquid) depending on the desired pH value in the pool. |
![]() | Off The automatic pH control is switched off. |
Timer functions pH value
Fill and/or flush pump hoses In the event that the pH dosing hose is empty (e.g. when changing canisters), you can start the pH-pump manually here to fill the hose. Stop the process as soon as the dosing hose is completely filled (i.e. up to the injection valve). Another menu helps you to rinse the dosing hose (e.g. when winterizing the tank). | |
![]() | Time limited dosage The pH pump can be switched on for a selectable period of time. You can choose whether the pH dosing should stop when the desired value is reached or only after the selected time has elapsed. You can stop the dosing manually at any time. |
![]() | Pausing the pH regulation The automatic control of the pH value can be stopped for an adjustable period of time. After this pause, the previously set regulation starts again automatically. |
Message list
All messages are listed in the message list. Additional information is displayed here for each message. In addition, AutomaticpH offers wizards for most messages that will guide you step by step to the solution.
If the issue cannot be solved despite following all the instructions, please contact your dealer.
Calibration – adjustment of the measured pH value
Please note that when calibrating the pH sensor using the enclosed buffer solutions, you must remove the sensor from its holder. Make sure that not too much water can leak out during this process.
Follow the instructions on the display
To avoid taking out the sensors, you can perform the calibration with the pool water.
Please measure the pH value with a photometer (e.g. BAYROL Electronic Pooltester)
Additional Options
KIT Smart&Easy Connector Flow – Flow monitoring
The optionally available KIT Smart&Easy Connector Flow allows you to install the pH sensor and the pH injection point (pH-Minus Liquid Domestic or pH-Plus
Liquid) in a particularly convenient and easy-to-maintain location.
The Smart&Easy Connector also includes an integrated paddle flow switch, which is connected to the
AutomaticpH by means of a simple plug-in connection.
KIT Level Automatic Single – Canister monitoring
The optionally available KIT Level Automatic Single allows direct monitoring of the filling level of the canister for pH-Minus Liquid Domestic or pH-Plus Liquid by using an easy-to-handle suction lance. When the canister is empty, a message is shown on the display. The KIT replaces the supplied foot filter and can thus be easily connected to the pre-designated level pH connection and mounted on the corresponding liquid container with the aid of a screw cap.
Winterizing
In colder temperatures, it is recommended to take the AutomaticpH out of operation (e.g. during the winter period).
The following instructions show you how to winterise your pool:
In case of active winterizing (pool filter system remains in operation)
- Stop the filter pump.
- Rinse the pump hoses with clear water.
- Empty all pump hoses.
- Remove the sensor from the holder and store it in its container, which is preferably filled with KCl solution or also with clean swimming pool water. Store the sensor in a dry and cool, but frost-free place.
- Insert a ½” plugs instead of the sensor holders.
- Store the canister for pH-Minus Liquid Domestic or pH-Plus Liquid in a dry and cool but frost-free place.
In case of passive wintering (filter system of the pool is switched off).
- Stop the filter pump.
- Rinse the pump hoses with clear water.
- Empty all pump hoses.
- Close and empty the filter system. Make sure that the entire pool circulation system is drained as much as possible.
- Remove the sensor from the holder and store it in its container, which is preferably filled with KCl solution or also with clean swimming pool water. Store the sensor in a dry and cool, but frost-free place.
- Store the canister for pH-Minus Liquid Domestic or pH-Plus Liquid in a dry and cool but frost-free place.
