Boiler control systems

Controller for automatic solid fuel boilers

This controller controls the ignition and combustion process in the boiler, bringing it closer to the ideal (6% oxygen). This is new generation microprocessor-based controller with color touchscreen.


The main advantages of the controller:

  • Boiler control;
  • Backup heating control;
  • Easy to use color touchscreen display;
  • BUS backbone allows you to connect additional modules;
  • The ability to connect the control unit with room thermostat;
  • The ability to adjust the amount of boiler ignition cycles;
  • Flame Test function before lighting the boiler;
  • Separate control burner cleaning (depending on the type of fuel used, you can change cleaning intervals);
  • Separate ash removal auger control (depending on the type of fuel used);
  • Support of the exhaust fan on the additional output (some boilers are equipped with a fan of the secondary air, which is necessary to control).

 The controller ensures operation of the following equipment:

  • burner (boiler temperature, flue temperature, water temperature)
  • pumps
  • exhauster (with frequency converter)
  • air supply fan (with frequency converter)
  • fuel supply system
  • fire-fighting equipment or devices
  • additional boilers (cascade control)

Lambda module with oxygen probe for automatic solid fuel boilers

The device is designed to ensure accurate measurement and maintain a given percentage of oxygen in the flue gases.

Using the lambda-probe:

  • reduces the amount of carbon monoxide emissions
  • reduces fuel consumption
  • significantly less likely to clean the chimney
  • increases the operational life of the burner (boiler),
  • reduced energy consumption

These measurement results are sent to the module through the internal protocol RS-485.
