The HERZ Thermiq system offers flexible communication options, allowing connection through three different versions, depending on the product type:
- Wired
- Wi-Fi
- Zigbee
Each version ensures reliable data exchange between room controllers, actuators, and the central control unit, while maintaining compatibility across the HERZ Thermiq ecosystem.
The HERZ Thermiq FanNova controller off ers advanced control for fan coil units and trench heaters, supporting both 2-pipe and 4-pipe confi gurations. Designed for modern comfort management, it ensures precise temperature and humidity regulation through optimized control algorithms. The controller provides fl exible operation of 3-speed 230 V fans, automatically adjusting fan speed based on demand. Integrated frost and overheat protection functions enhance safety, while the built-in ECO mode helps reduce energy consumption and operational costs.
The device communicates via Wi-Fi 2.4 GHz and MODBUS RS-485, enabling seamless integration into smart control systems. Its intuitive user interface and simple confi guration process make installation quick and convenient for professionals. With support for mixed installations—such as fan coils combined with underfloor heating—the FanNova off ers versatile functionality suitable for both residential and commercial applications
