he Universal Dosing Station for controlling and maintaining the pH (hydrogen ion concentration), Cl (free chlorine), and Rx (oxygen-reduction potential) of the swimming pool water.

  • For pools of volume:
  • from 1 to 250 cubic meters - private;
  • from 1 to 150 cubic meters - public.
  • Built-in remote access via Bluetooth and Wi-Fi.


A high-precision algorithm of adaptive dosing logic for any type of chemistry for swimming pool water allows achieving the best parameters, maintaining the required concentration of chemicals in the pool with extreme precision.

Automatic cleaning of the amperometric chlorine sensor. By supplying voltage to the electrode sensor, the station automatically performs a cleaning of the sensor's metal case from oxidation. This function allows significantly extending the sensor's lifespan and reducing the need for its servicing.

Three galvanically separated inputs allow significantly increasing the accuracy of measurements of pH, Cl, and Rx, and consequently, the subsequent dosing control of chemical substances.
Control of the state of the pH, Cl, and Rx sensors. The station, according to a special algorithm, analyzes the readings from the electrode sensors at the beginning of each dosing cycle and, in case of no response to dosing, sends a notification to check the state of the sensors and calibrate them.

Two silencio-peristaltic pumps with a performance of up to 2.2 l/h (optional 1.5 l/h) and one external peristaltic pump with a performance of 1.5 l/h with the ability to set up for dosing any type of chemistry for swimming pools. The second dosing pump can be assigned for any type of chemical for the swimming pool (default: 1 - pH, 2 - Cl, 3 - Floc).

The ability to connect an unlimited number of duplicate dosing pumps with a performance up to 2.2 l/h.

Exclusion of simultaneous dosing of agents Cl and pH, as their mixing leads to the formation of toxic chlorine gas in gas form.

Built-in overdosing protection - a regulated setting of the maximum allowable daily dosing volume of chemical substances required to achieve the required concentration in the pool water. The daily dosing volume is set for each type of chemical. When the upper limit is reached, the station stops the dosing process until the current days are completed. In the next day, if no response from the sensor is detected, the station switches to uniform daily dosing until the measuring sensor is re-calibrated, thus excluding the sudden consumption of the daily limit.

Control of the level of chemicals in the canister. The chemical level sensor prevents water runoff in the dosing line, which prevents chloride crystallization. The pump stops when the chemical level in the canister is monitored (suction nodes ACON are included in the kit).

The station includes three flow control options:

  • Connection to the station with 220 V and the filter pumping station;
  • Connection of the filtration control block;
  • Connection of the flow sensor.

The ability to measure and indicate the temperature of the water in the pool with the help of a temperature sensor (purchased separately).
Dosing, measurement, and event logs. The station keeps logs of the use of chemical substances, pH, Cl, Rx, and temperature, as well as logs of events such as emergency situations and daily dosing reports for each type of chemical.


A matrix display with an intuitive interface in Russian and English. 6 control buttons allow you to easily navigate through the station's menu.
Built-in Wi-Fi and Bluetooth modules. Remote control is done through mobile applications ACON WEB CONTROL and ACON Bluetooth CONTROL.
Access to the application is divided into 3 levels:

  • Work. The user section with the ability to monitor values and changes in them, the range of which is set in the service section. It also includes the ability to change the pool loading mode.
  • Settings. The service personnel section with the ability to monitor statistics.
  • Service. The 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 at the site. By default, passwords are set for the settings and service sections. This level of division allows access according to the competence of the employee or user.

Notifications via E-mail. 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, thereby preventing potentially dangerous situations before they become critical. In the settings, you can set up to 3 email addresses to receive emails.

RS-485 interface for connection to "Smart Home" systems.
