The ingeniously designed burner allows burning of various pellets, even of worse quality and agro-pellets

  • ROTARY COMBUSTION CHAMBER, maintenance-free solution for burning pellets. It is sufficient to check it before heating season.
  • AIR DISTRIBUTION TO PRIMARY AND SECONDARY COMBUSTION, patented mechanism, which ensures highest efficiency of combustion and possibility to set optimal combustion of various kinds of pellets (not applied to 16 kW and 20 kW).
  • BLOWER CHAMBER, automatic cleaning of aeration chamber is common turning of combustion and aeration chamber. This method of automatic cleaning completely eliminates the need of manual cleaning. This eliminates periodic disassembling of the burner and service.
  • BURNING VARIOUS PELLETS/AGRO-PELLETS, where all problems are eliminated, and combustion process is optimized by distribution of primary and secondary air.
  • FULL AUTOMATIC, unattended and maintenance-free operation.

Automatic controller

ecoMAX 860P

Automatic controller ecoMAX 860

Sophisticated control software allows you to set the required boiler output and regulate the boiler with continuous operation.

Special algorithms of the control unit adjust rotations of exhaust fan to keep the air flow stable, according to values measured by air flow meter. This assures optimum combustion in the boiler. Burning process is stable and independent on weather conditions, chimney draft and possibly unclean exchanger. Operation in the vacuum mode is much more safe and eliminates the risk of back fire.

Controller's features:

  • exhaust fan control
  • modulating pellet burner output
  • pellet feeder control
  • boiler pump
  • HUW pump
  • HUW circulation pump
  • mixer pump
  • mixer control
  • thermostat support
  • buffer loading control
  • summer/winter mode
  • flue gas sensor
  • weather control
  • time schedules
  • STB emergency thermostat
  • reserve boiler switch



Internet system ecoNET

Internet system ecoNET provides to user option for remote control of the boiler and heating installation. Thanks to that user has possibility to change almost all parameters of boiler and heating system operation, but also view the history of the operation which is displayed on a clear graph.

Remote acces to controller is possible from every device which is connected to internet, as it is tablet, laptop or mobile phone. Settings can be made via a web browser on or through a mobile application which is available for Android and iOS.

Schema of internet system

Online service. The internet system is not only for user. It is useful also for service company, which may have access to the boiler data and if neccessary the service company can change the controller settings. The internet system lowers the costs for service intervention significantly.

Accessories for controller:



Remote control panel with room thermostat function ecoSTER TOUCH allows you to control and change the boiler’s settings from the place, where is the thermostat installed, for example the living room.

Internet module

Additional module for controlling another heating circuits

Allows controlling of another two mixing circuit and their pumps. Also it allows to control circulation pump for HDW.
