    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 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.

    Key features

    – Factory made 65 ft data-cable extension.
    – Compatible with both Harvia Xenio and Fenix control units.
    – Durable shielded cable with RJ 10 connectors on both ends.
    – Maximum total cable length (including original cable) is 80 ft, as recommended in Harvia manuals.
    – Flexible and durable cable jacket; manufactured by Harvia in Finland.

    Specifications

    Length: 65 ft
    Connectors: RJ 10 male to male (4P4C)
    Compatibility: Harvia Xenio & Fenix control units
    SKU: WX319 65FT

    1. Turn off power to your sauna.
    2. Remove the existing data cable from your control panel and power unit.
    3. Connect one end of the extension cable to the control panel and the other end to the existing cable at the power unit.
    4. Route the cable along walls or through conduit as needed. Avoid running near high voltage wires to reduce interference.
    5. Restore power and verify that the control panel communicates with the sauna heater.

    This cable is a safety component and cannot be returned once installed. Do not exceed the total control cable length specified above.

      PLAN THE WHOLE SAUNA

      The room and heater still have to work as one system.

      Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.

      Compare sauna heaters

      See electric sauna heaters by output, stone mass, control style, and installation type. Size from adjusted room volume, not floor dimensions alone.
