Bring cutting-edge smart technology, exceptional performance, and premium touch controls to heavy-duty electric heaters with the Harvia Fenix WiFi FX170 Core control unit, engineered for large saunas up to 17 kW.

The Harvia Fenix FX170 WiFi Core is a high-capacity digital control hub designed to offer first-class management and modern luxury in environments where high heating power is required. This professional-grade system is the perfect choice for large family saunas, residential complexes, hotels, public spas, and commercial wellness centers.

AI-Powered Sauna Expertise & Thermal Optimization

The Fenix FX170 is far more than a standard digital thermostat—it is an intelligent system that actively tracks, analyzes, and learns your specific sauna room’s unique thermal heating profile. Tailor your spa experience instantly by selecting from three curated factory presets (Gentle, Pleasant, or Intense) or easily customize and store your own favorite combinations. Its smart integrated timer learns exactly how long your sauna takes to reach the target temperature, ensuring the benches are perfectly warm the precise moment you plan to step in.

Total Management, Commercial Safety, and Luxury Design

Featuring a sleek 4.3-inch black glass touchscreen panel, the system provides a fluid and intuitive user interface to manage your heater, lighting, and ventilation systems. To ensure 100% safe remote preparations, the package includes a wireless safety door sensor as standard. A secure PIN-code screen lock and a specialized guest mode make this unit an outstanding, tamper-proof solution for hotels, commercial gyms, or shared community saunas. With its heavy-duty build, the elegant touch panel is certified to be installed directly inside the sauna room.

Smart Remote Connectivity via the MyHarvia App

Equipped with built-in WiFi connectivity, the Fenix FX170 lets you monitor your sauna's status in real-time from your smartphone.
