The Sequetrol® IoT belongs to a new generation of control units developed to meet the requirements of the Internet of Things (IoT) and Smart Home. It combines the possibility to handle even the most complex sewage treatment processes with connectivity and remote operability.


The integrated webserver of the IoT controller series allows you to operate the treatment plant and to access all information with any browser.
Imagine, you’d like to service a plant and the owner of the building is not at home—simply access via Wi-Fi without entering the building.
Imagine you would like to operate a big plant with a touchscreen—simply add a standard tablet to the control cabinet and connect via Wi-Fi.
Imagine, your plant has some troubles and you don’t like to go hundreds of kilometers—simply connect via GSM and operate and analyze the plant.


REST using JSON over HTTP is a widely used standard for M2M communication. The control unit can thus be integrated into any code base that can communicate over HTTP, including .NET, Java, Python, scripting environments like PHP or JavaScript, and more! Like this, an efficient data exchange between the control unit and telemetry servers, PLC and SCADA devices is possible.


The innovative water-level sensing by pressure measurement allows cost-effective detection of pre-set water levels without the use of failure-prone float-switches.


With the Sequetrol® IoT there are no restrictions to your ideas. BONNEL’s PC software MenuMaker 4 enables you to program even the most complex processes and menus without being a programmer. The IoT controller supports multiple, connected programs, calculations within the process, analogue water level evaluation, automatic switching-off of airlifts, user defined alarm conditions, timers, counters and much more.


The IoT platform can help you to create new business models.
You want to rent your plants? Block the plant automatically when no payment is arriving.
You want to compete with big plants? Connect to SCADA and offer touchscreens.
You want to reach remote areas? Control and monitor your plant remotely.
You want to do PPP or provide cleaning as service? Prove your plant is running well connecting sensors to the analogue input and transfer all data to telemetry servers in the cloud.


The optional analogue input can be used for a further optimization of the wastewater treatment process. Properties, such as the turbidity of the treated water can be analyzed.
Up to four external digital signals can be monitored and processed within the control algorithm.
Up to 8 relay outputs for 230VAC offer a comfortable connection of solenoid valves, diaphragm blowers, submersible pumps or other loads.
The optional GSM module can be used to monitor the plant together with the BONNEL Aquavisor® telemetry server.
All electrical connections are made using reverse polarity protected plugs with IP54 rating. Of course the type of connectors can be changed according to customer requirements.


The extent of the system functionality and the design of the front panel of the Sequetrol® control unit can be tailored to match your individual needs.
The Sequetrol® advanced IoT is equipped with features as acoustic signaling of predefined conditions, rechargeable batteries to signal mains failure and non-volatile EEPROM memory for programs, event logs and an electronic operating book.

  • Easily programmable control unit for decentralized SBR sewage treatment plants
  • Water-level sensing by pressure measurement
  • Up to 8 + 1 relay outputs
  • Individually equipped according to customer requirements
  • Multi-language menu
  • GSM-module as option

  • Water-level control without expensive and unreliable float switches means no more electricity carrying parts in the cesspool.
  • Reliable technology proven in thousands of sewage treatment plants
  • Up to 8 + 1 relay outputs (8 x 230VAC, 1 x low voltage) for an easy connection of accessory devices
  • Event protocol with event, date & time and program step
  • Individually equipped according to customer requirements
  • Sequence program can be easily created and modified with the PC software MenuMaker 2
  • Password protected operating levels
  • Updateable firmware and software
  • Rechargeable batteries for mains failure alarm

The innovative water-level sensing by pressure measurement allows cost-effective detection of pre-set water levels without the use of failure-prone float-switches.


The Sequetrol® control unit is especially suited for sophisticated SBR control algorithms with normal and eco mode and multiple programs for different numbers of inhabitants or different plant types. The programs can be chosen on-site. This can help to reduce the number of different control units on stock.
The program can be triggered by the daytime, so day / night mode or similar is possible.
The Sequetrol® has an in-build memory for event logs and for an electronic operating book. The operating book will store basic information about the regularly performed owner maintenance checks. The event logs as well as the electronic operating book can be transferred from the Sequetrol® to a PC using a special memory key.
The menu is prepared for up to five languages. The languages can be switched on-site.
The menu access can be restricted in up to three different access levels (user, service, admin).


The optional analogue input can be used for a further optimization of the wastewater treatment process. Properties, such as the turbidity of the treated water can be analyzed.
Up to four external digital signals can be monitored and processed within the control algorithm.
Up to 8 relay outputs for 230VAC offer a comfortable connection of solenoid valves, diaphragm blowers, submersible pumps or other loads.

  • Easily programmable control unit for small SBR treatment plants
  • Adjusting of the step times can be done on-site using three buttons on the printed circuit board
  • Keeps record of last performed step in an event of mains failure
  • 5 relay outputs (230V)
  • Digital input for float switch
  • Acoustic alarm and mains failure signalization
  • Also available as special version for price-sensitive Pump-SBR wwtp

  • Compact control unit that stands out due to its price performance ratio
  • Backlit 2x16 character LCD allows to have step names, alarm messages and operating hours clearly displayed during operation
  • Even people without programming experience can easily create a program by editing an Excel® spreadsheet
  • Individually equipped (display, keypad, connectors) according to customer requirements
  • Integrated operating hours counter
  • Automatic release of residual pressure in the valve unit
  • Updateable firmware and software
  • Design of the front-panel according to customer preference

The extent of the system functionality and the de-sign of the front panel of the Sequetrol® compact LCD control unit can be tailored to match your individual needs.
The Sequetrol® compact LCD is also available with features, such as, acoustic signaling of predefined conditions, a sequence program permanently stored in the EEPROM, and a set of batteries (optional NiMH rechargeable batteries) to ensure continuous signaling during power outage.
The built-in backlit 2x16 character LCD allows to have step names, alarm messages, operating hours and other user specific information, clearly displayed during operation.
When the control sequence is interrupted due to mains failure, the unit will automatically resume operation with the last unfinished step instead of restarting the program.
Utilizing the three buttons on the circuit board, the sequence timing can be readjusted at the installation site, resulting in an increased flexibility in adapting the Sequetrol® compact LCD to the individual requirements of the particular plant.
Build-up of residual pressure in the valve unit is prevented by stopping the compressor before closing the valves. Timing is individually adjustable for each program step (0 - 14s).


Available digital input can be used to connect a float-switch or another sensor.
Up to 5 relay outputs for 230VAC offer a comfortable connection of solenoid valves, diaphragm compressors or other loads.


The programming process was developed especially with regard to the demands of a real decentralized SBR sewage treatment plant.
The control unit will be delivered ex-factory already preprogrammed according to customer requirements. Firmware updates and sequence program changes can be performed with the aid of an inexpensive programming device. This also makes the Sequetrol® compact LCD “future-proof” and ready for possible changes of the legal situation.
No programming experience or any special software is needed.
The sequence program can be easily created or modified using a ready-made spreadsheet table (Excel®).
