Description
The Harvia Fenix FX30C-U3-XC is a premium touch control panel with Wi-Fi connectivity designed specifically for Virta Combi Series sauna heaters operating on 3-phase power. Combining the Fenix's intelligent glass screen interface with dedicated combi heater control and full remote Wi-Fi management, this unit gives you independent command over both the heater and the steamer — from anywhere in the world via the MyHarvia app.
The glass screen control panel is easy to install wherever it suits your space — in the sauna room, bathroom, or even the living room. With Wi-Fi connectivity, you can monitor and adjust your sauna settings remotely, ensuring it is always at the perfect temperature and humidity when you are ready. Sauna heater sold separately.
Smart Combi Control Performance
The FX30C-U3-XC combines the Fenix's intelligent interface with full combi sauna functionality — the heater and steamer can be controlled independently, giving you precise command over both dry heat and steam levels simultaneously. Temperature and humidity are regulated separately, and lighting, ventilation, and timer settings are all managed from the single glass touchscreen interface or remotely via Wi-Fi.
Rated for up to 10.8kW at 208V 3PH, the FX30C-U3-XC is the premium Fenix combi control for 3-phase Virta Combi installations — the direct upgrade over the standard CX30C-U3 Xenio control, adding Wi-Fi connectivity and Fenix's glass screen interface.
