Harvia Fenix FX30C-U3-XC Wi-Fi Touchscreen Sauna Control
3-Phase Virta Combi Series | Up to 10.8 kW | Steam & Heat Control | Wi-Fi Remote Access
The Harvia Fenix FX30C-U3-XC is a Wi-Fi enabled glass touchscreen control unit designed for 3-phase Harvia Virta Combi Series sauna heaters. It gives you independent control over both the sauna heater and steam generator — including temperature, humidity, lighting, and ventilation — from the panel or remotely via Wi-Fi. Supports heater outputs up to 10.8 kW and installs surface-mounted or flush-mounted.
The FX30C-U3-XC is built for 3-phase combination sauna environments where both dry heat and steam need to be managed together. Its glass touchscreen interface is intuitive in low-light sauna conditions, and the built-in Wi-Fi lets you preheat your sauna remotely before you’re ready to step in. Compatible exclusively with 3-phase Harvia Virta Combi Series heaters.
