The main advantage of the ST-05 model is a very clear LED display, which transparently and immediately informs the user about the current water temperature in the system and the operating status of individual peripheral devices, such as pumps or the blower. The intuitive user interface allows for rapid configuration of operating parameters, which is crucial for maintaining high thermal comfort for residents under changing weather conditions.
Operational safety is a priority for the manufacturer, which is why the controller is equipped with an extensive alarm system. It signals emergency situations, such as dangerous boiler overheating or temperature sensor failure, using audible signals and on-screen messages. The robust and aesthetic housing made of high-quality materials effectively protects sensitive electronics from the harsh conditions found in boiler rooms, such as dust, dirt, or moisture.
The device supports full automation of heating processes, which minimizes the need for constant, burdensome supervision of the furnace. By choosing the Diamond ST-05 controller, you are investing in reliability, durability, and modern technology that not only facilitates daily life but also cares for the environment by optimizing the combustion process. It is an ideal solution for those seeking a compromise between advanced functionality and ease of use in the daily operation of a heating system.

The Diamond ST-05 LED controller is an advanced electronic device designed for the precise management of modern heating systems. This device integrates control functions for the central heating (CH) pump, the domestic hot water (DHW) pump, and the blower fan in solid fuel hopper boilers. Thanks to the use of a modern microprocessor, the controller ensures optimal fuel combustion in the boiler and extremely efficient heat distribution throughout the building, which translates into real financial savings and lower fuel consumption.

Software and control algorithms
The ST-05 LED device features advanced control software that allows for precise management of the combustion process. The user has the ability to fully configure fan parameters, including setting the blast force, blow-through time in maintenance mode, and intervals between these blow-throughs. The control algorithm intelligently manages pump priorities - it is possible to set a priority for domestic hot water (DHW), which allows for faster preparation of water for bathing, or operation in summer mode (DHW only). The software interface is intuitive and allows for a quick view of temperatures from both sensors. The safety system constantly monitors the continuity of measurement circuits; if a sensor fault is detected, the software immediately turns off the fan and starts the circulation pumps to prevent uncontrolled temperature rise in the boiler. The entire software has been designed with maximum energy efficiency and extending the service life of connected mechanical devices in mind.
