Overview
SmartHexa UFH is equipped with an advanced electronic control system that ensures maximum efficiency and prioritizes domestic hot water (DHW) production. The unit continuously monitors temperature, pressure, and flow at multiple points to maintain optimal operating conditions. With a stainless steel heat exchanger and piping, the system delivers high durability and provides the low, stable temperatures required for underfloor heating. Its integrated mixing configuration ensures stable supply water temperature for maximum comfort. An optional outdoor compensation control allows quick adaptation to changing ambient conditions, improving energy efficiency. Proportional motorized valves and advanced control algorithms provide precise temperature management in the heating circuit. The electronic control system also offers smart features such as easy PC setup and commissioning, district return temperature control, enhanced anti-legionella function, and a “keep warm” mode for low return temperatures. SmartHexa UFH allows remote monitoring and control by transmitting all operational data to the BLES system.
