The multi-functional dosing station for controlling and maintaining the pH (hydrogen ion concentration) and Rx (oxygen reduction potential) of a swimming pool water.
For private pools of volume from 1 to 250 cubic meters.



  • Dosing and control;
  • Pool filtration control;
  • Pool heating control;
  • Pool water level control;
  • Automatic reverse flushing control;
  • Built-in remote access via Bluetooth and Wi-Fi;


A high-precision algorithm of adaptive logic dosing any kind of chemistry for the swimming pool water allows achieving the best parameters, maintaining the required concentration with high precision.
Two galvanically separated inputs allow significantly increasing the accuracy of measurements of pH and Rx and, consequently, subsequent dosing control.
Control of the state of the pH and Rx sensors. The station follows a special algorithm every dosing cycle analyzes the readings from the electrodes and in case of no response to dosing, it sends a notification to check the state of the sensors and calibrate them.
Two silencio-peristaltic pumps with performance of 2.2 L/h (optional 1.5 L/h) with the ability to set up for dosing any kind of chemistry for swimming pools.
The second dosing pump can be set up for any kind of chemistry for swimming pools (default: 1 - pH, 2 - Cl).
The ability to connect up to two additional externally controlled dosing pumps with a performance of up to 2.2 L/h or 1.5 L/h for dosing any kind of chemistry.
The ability to connect an unlimited number of duplicating dosing pumps with a performance of up to 2.2 L/h.
Exclusion of simultaneous dosing of Cl and pH-reagents, as their mixing leads to the formation of toxic chlorine gas in gas form.
Built-in overdose protection - this adjustable setting of the maximum allowable volume of the daily dose of chemical preparations, necessary to achieve the required concentration in the pool water. When the upper limit of the specified volume is reached, the station stops the dosing process to complete the current days. In the next day, in case of no response from the sensor for dosing, the station switches to uniform daily dosing until the measuring sensor is re-calibrated, thus excluding the momentary daily limit.
The ability to connect a chemical level sensor in the canister. The chemical level sensor prevents water from backflowing into the dosing line, which prevents crystallization of chlorine. The pump stops when the level of the chemical in the canister is monitored (the ACON collection node).
Flow control. The station includes a flow sensor.
Dosing, measurement, and event logs. The station maintains logs of chemical reagent consumption, pH, Rx, and temperature values, and a log of event records, which records emergency situations and daily reporting on dosing of each kind of chemistry.


Starting and stopping the pumping station pump with a power of up to 2.2 kW, 220 V.
In the settings, four loading modes are set:


Starting and stopping the pumping station pump with a power of up to 2.2 kW, 220 V.
In the settings, four loading modes are set:

  • Small - 3 hours of work, 5 hours of pause;
  • Medium - 5 hours of work, 3 hours of pause;
  • Large - 7 hours of work, 1 hour of pause;
  • Public - 24-hour operation.

Automatic setting of the current consumption of the pumping station pump is made using the calibration of the pump in the menu.
Built-in overload and «dry run» protection ensure long-lasting and reliable operation of the pumps.
The station includes 3 timeout restarts for the pump in case of an emergency situation.


Using a temperature sensor (supplied separately), the station measures the temperature of the swimming pool water and, if necessary, turns on or off the operational devices of the heat exchanger (circulation pump for heating, electromagnetic valve or electromagnetic contactor for electric heater).


When two submersible, conductometric, or peristaltic level sensors are connected, the station maintains the desired water level in the swimming pool by controlling the electromagnetic valve (sensors are purchased separately).
Wide range of settings:

  • Regulation of averaging: from 1 to 60 seconds;
  • Regulation of the duration of the refill: from 1 to 90 minutes;
  • Duration of the pause between refills: from 1 to 10 hours.

Allows using the system with different types of water level oscillations (waves).
Adaptation of the refill for low-performance wells and boreholes.


The station manages the AUTOCLEAN S-Light filter reverse flushing, fully automating this process.
In the settings, the parameters for the flushing, draining, depressurizing, and pause are set:
Daily scheduling with the possibility of setting up to two flushes a day;
Choice of the operation mode of the filter pump during the flushing period;
The limit value of pressure at which a forced reverse flush is made (pressure sensor is purchased separately). 


A matrix display with an intuitive interface in both Russian and English languages. 6 buttons for controlling the menu.
Built-in Wi-Fi and Bluetooth modules. Remote control is performed through ACON WEB CONTROL and ACON Bluetooth CONTROL mobile applications.

Access to the application is divided into 3 levels:

  • Work. A user section with the ability to monitor values and changes within the ranges set in the service section. It also allows changing the pool loading mode.
  • Settings. A service section with the ability to monitor statistics and change filtration, reverse flushing, and refilling modes.
  • Service. A service section with the ability to change all the functions of the dosing station via Bluetooth. In the WEB version, some functionalities are not available because some settings such as sensor calibration or changing the assignment of dosing pumps require physical presence on the object.

By default, passwords for the settings and service sections are set. This division into levels allows access according to the competence of the employee or user.
E-mail notifications. The station itself forms a message and sends it to the specified email addresses in the settings. This feature allows for immediate response to problems in the swimming pool, which prevents potentially dangerous situations before they become critical. In the settings, you can set up to 3 email boxes to receive emails.
RS-485 interface for connection to «Smart home» systems.
