The paper presents a new approach to the design of the solar thermal system controller which is characterized by modular arrangement. The proposed solution enables the integration of controller functions that significantly improve user comfort and the overall reliability of the system. These functions may include both security operations (control of blinds for solar collector, emergency power supply) as well as system monitoring (heat meter, data logger with memory card, Internet-based monitoring, weather station).
