Harvia Xenio & Fenix Data-Cable Extension – 65 ft (20 m) WX319

Extend Your Control Panel, Expand Your Sauna Experience

The Harvia Xenio & Fenix Data‑Cable Extension lets you relocate your digital control panel up to 65 ft (20 m) from the sauna power unit. This is perfect when you’d rather adjust sauna settings from a comfortable dry space like a changing room or living area instead of inside the hot sauna.

Why extend your cable?

– Safer and more convenient: keep the control panel cool and dry and avoid bending over or reaching awkwardly to adjust the temperature.
– Custom installation: ideal for larger rooms or when the power unit sits behind a wall or in a mechanical closet.
– Plug-and-play reliability: genuine Harvia RJ 10 connectors on both ends mean no cutting or crimping and ensure a secure signal.
