The ST-04 LED controller is an advanced electronic device designed for precise management of the central heating circulation pump and blower fan in solid fuel boilers. Thanks to the use of a modern microprocessor, the regulator ensures an optimal combustion process for wood, coal, and coal dust, which directly translates into fuel savings and increased thermal comfort in the building. The device is characterized by intuitive operation and a clear LED display that informs the user about the current temperature and operating status of the connected devices in real time.
The use of the controller allows for significant automation of the combustion process, eliminating the need for constant supervision of the boiler. Precise blower control prevents sudden temperature spikes, which protects the installation from damage and extends the service life of the boiler itself. It is an ideal solution for those looking for a reliable and easy-to-configure home heating control system that combines functionality, economy, and safety.
The main advantage of the controller is the ability to choose from five dedicated operating modes, which have been optimized for specific types of fuel. Modes F1 to F4 offer ready-made algorithms for blower power control and blow-throughs, while mode F5 allows for full personalization of settings according to individual installation needs. Operational safety is enhanced by a built-in alarm system that warns against boiler overheating. Solid construction and high-quality components guarantee long and trouble-free operation of the device in the difficult conditions prevailing in boiler rooms.

The device is equipped with an advanced microprocessor controller with dedicated software optimizing the combustion process. The user interface is based on an intuitive panel with an LED display and function buttons, which allows for quick changes of operating modes (F1-F5) and precise editing of technical parameters in manual mode. The software implements blower power control algorithms, manages blow-through cycles to remove flue gases, and controls the activation temperature of the circulation pump. The system has integrated protective functions, including an audible alarm activated when the permissible boiler temperature is exceeded, which prevents installation failures. Additionally, the controller monitors the extinguishing and ignition process, automating transitions between boiler operating states.
