Product Benefits

If your Harvia sauna runs on a Xenio control, this is the part that modernizes it without replacing the wiring. The Harvia Fenix FX001XW is the 4.3 inch glass touchscreen panel on its own, sold separately from the power unit, and Harvia describes it as a plug and play update for Xenio control panels. Swap the panel, keep the power unit already in the wall, and you get the app, the learning timer and the presets that come with the current sauna heater control line.

The FX001XW has no power unit, so it cannot run a heater alone. It replaces the panel on an existing system. Building a new sauna, or replacing a failed power unit, means buying a complete Harvia Fenix control unit instead, which includes both parts. Harvia's compatibility statement covers Xenio control panels. It does not publish a compatibility list by heater model for this panel, so confirm your exact setup with us before ordering rather than assuming it fits.

Harvia sets a minimum advertised price on the Fenix line and enforces it, so the number is the same at every authorized dealer. What differs is whether anyone checks the fit before your money moves.

The panel is 3.4 by 4.4 by 1 inch and 0.4 lbs, 1.5 lbs boxed. It mounts on the surface or recessed, rated for the sauna room, a bathroom or a living space. Temperature adjustment runs from 85°F to 229°F. The box holds the panel, a 5m panel cable, screws and the manual. Harvia states this panel includes a MyHarvia Control subscription.

Heaters with controls built into the unit, which have no separate panel to replace

Panel Only or Complete Control

The difference is the power unit, the box that switches the heater. This panel assumes yours is installed and working. A complete Harvia Fenix control unit includes both parts and is the right choice for a new install. If you are still running the older generation and want to see it before deciding, the Harvia Xenio digital control is the system this panel upgrades.

BEFORE YOU ORDER

Confirm two things: that you have a separate wall panel rather than controls built into the heater, and which system it belongs to. Harvia's compatibility statement names Xenio panels and lists no heater models, so we verify the rest against your setup.

Why This Is the One to Buy

Most people who want app control of an existing sauna assume they need a whole new system. On a Xenio setup they usually do not.
