Harvia Fenix WiFi Core Control Panel - Next-Generation Smart Sauna Control — Connected Performance, Anywhere.
Experience the future of sauna control with the Harvia Fenix WiFi Core, a next-generation smart controller designed for effortless operation, total flexibility, and connected living. With a sleek 4.3" touchscreen panel, built-in WiFi, and full remote access via the MyHarvia 2 app, this control system lets you preheat, schedule and manage your sauna from anywhere — home, work, or on the go.
Available in two power ratings: the 11 kW (FX110) with a moisture-resistant IPX5 power unit, and the 17 kW (FX170) for larger and commercial saunas. Both ship with a 3-month free trial of the Control license, unlocking remote heater start out of the box.
Intelligent, Self-Learning Control
What sets the Fenix apart is its intelligence. The control system continuously learns with AI — adapting to how your specific heater and sauna room behave over time. It fine-tunes pre-heat timing and performance so the sauna is ready exactly when you want it, and the more you use it, the smarter and more efficient it becomes. No more guesswork, no wasted energy — just a perfectly prepared sauna, session after session.
Fenix vs Xenio CX170
The Fenix is Harvia's next-generation control platform. It builds on everything the trusted Xenio CX170 offers and adds AI-adaptive heating, built-in WiFi with automatic over-the-air updates, the new MyHarvia 2 app, customisable heating profiles, and PIN-protected guest mode. If you want the latest connected, self-learning sauna experience, the Fenix is the natural upgrade — while the proven Xenio CX170 remains an excellent choice for a straightforward smart controller.
