DOZBOX 2 PRO

A multi-function station for dose control and maintenance of pH (hydrogen ion concentration) and Cl (free chlorine in the swimming pool water.
For pools of volume:

• from 1 to 250m³ - private;
• from 1 to 150m³ - public.

FUNCTIONS:

• Dose control and monitoring;
• Management of water filtration in the swimming pool;
• Management of the control of the heating curve of the swimming pool water;
• Monitoring the level of water in the swimming pool water;
• Automatic reverse chlorination control;
• Built-in remote access via Bluetooth and Wi-Fi;

DOSE CONTROL AND MONITORING:
A high-precision algorithm for adaptive logic dosing of any type of chemistry for the swimming pool water allows achieving the best parameters, maintaining the required concentration with maximum precision.
Automatic cleaning of the amperometric sensor of free chlorine. By applying a voltage to the sensor electrode, the station automatically cleans the silver base from oxidation. This function allows significantly extending the service life of the sensor and reducing the necessity of its servicing. 
Two galvanically isolated inputs allow significantly increasing the accuracy of the measurements of pH and Cl and, accordingly, the subsequent dosing control of chemical agents.
Monitoring the state of the pH and Cl sensors. The station monitors the special algorithm of each cycle of dosing, analyzes the readings from the sensor electrodes, and in case of no response from the sensor to dose, sends a notification to check the state of the sensors and subsequently calibrate them.
Two additional externally controlled dosing pumps can be connected, with a performance of 2.2 l/h (optional 1.5 l/h) for dosing any type of chemistry for swimming pools.  The second dosing pump can be assigned to any type of chemistry for the swimming pool water (default: 1 - pH, 2 - Cl).
The possibility of connecting up to two additional dosing pumps with a performance of 2.2 l/h or 1.5 l/h for dosing any type of chemistry.
The possibility of connecting an unlimited number of duplicating 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 in gas form.
Built-in overdose protection - this adjustable setting of the maximum permissible daily dose of chemical agents, necessitating the water in the swimming pool, ensures the long-term reliability of the station. The daily dose is set for each type of chemistry. If the upper limit of the set volume is reached, the station stops the dosing cycle to complete the current day. In the following days, in case of no response from the sensor, the station transitions to uniform daily dosing until the sensor is re-calibrated, thereby excluding the momentary dose limit.
Control of the level of chemistry in the canister. The sensor level allows you to avoid water flooding in the dosing line, which prevents crystallization of chlorine. The pump stops when the level of chemistry in the canister is monitored (Acon ACON WEB CONTROL inclusions).
Control of flow. The station includes a flow sensor.
Dosage, measurement, and event logs. The station maintains logs of the use of chemical agents, values of pH, Cl, and temperature, as well as a log of events, which records emergency situations and daily reporting on the dosing of each type of chemistry.

FILTER MANAGEMENT:
Starting and stopping the filter pump's performance of up to 2.2 kW, 220 V.

The settings include 4 loading modes:

• 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 mode.

The current setting of the filter pump is automatically set using the remote control menu.
Built-in overload and «dry run» protection for the current consumption of the filter pump ensure the long-term and reliable operation of the pumps.
The station includes 3 timeout restarts for the filter pump in case of an emergency situation.

HEATING CONTROL:
The temperature sensor (supplied separately) measures the temperature of the swimming pool water and, if necessary, turns on or off the operational devices of the heat exchanger (circulating pump heating, electromagnetic valve, electromagnetic heater control).

WATER LEVEL CONTROL:
When two water level sensors, conductivity, or submersible level sensors are connected, the station maintains the required water level in the swimming pool by controlling the electromagnetic valve (sensors are available separately).
Wide range of settings:

• Smoothing regulation: from 1 to 60 seconds;
• Dosing duration regulation: from 1 to 90 minutes;
• Pause duration, between dosings: from 1 to 10 hours.

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

AUTOMATIC REVERSE CHLORINE CLEANING:

The station manages the reverse chlorine cleaning of the AUTOCLEAN S-Light filter automatically, completing the entire process.
The settings include:

• Durations of cleaning, tightening, draining and pause;
• Cycles of cleaning. A weekly schedule with the possibility to schedule up to two cleanings a day;
• Selection of the operation mode of the filter pump during the cleaning period;
• The maximum value of pressure at which a forced reverse chlorine cleaning is performed (pressure sensor is available separately). 

INTERFACE:
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 carried out through mobile applications ACON WEB CONTROL and ACON Bluetooth CONTROL.
Access is divided into 3 levels:

• Work. A user section with the ability to monitor values and changes in them, the frame of which is set in the service section. It also allows you to change the loading mode for the pool.
• Settings. A section for maintenance staff with the ability to monitor statistics and change the modes of filtering, reverse chlorine cleaning, and dosing.
• Service. A service section with the ability to change all the functions of the dosing station by 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 division allows access according to the competence of the staff member or user.

Notifications by E-mail. The station forms the message itself and sends it to the specified email addresses in the settings. This feature allows for immediate reaction to problems in the swimming pool, which helps prevent potential 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.
