Harvia Fenix / Xenio Power Unit — Replacement Control Box (No Screen)

This is the power unit, the metal control box that comes with a Harvia Fenix or Xenio control panel. It's the part that's wired to your heater and does the heavy lifting: it switches the heater's power, reads the sauna temperature sensor and talks to the touch screen out in the sauna.

If the box has been damaged, or you've lost power to the heater and the circuit board isn't the only problem, this lets you replace just the box and keep the screen you already have. Screen not included.

Which one do I need?

Match the box to the model of your control panel (it's on the label inside the box and in the Harvia app):

Not sure which you have? Send us a photo of the label or your panel and we'll confirm it for you.

What's included

• Genuine Harvia power unit (control box) with circuit board fitted
• Installation and operating instructions
• Touch screen display, temperature sensor and data cable not included, you keep your existing ones

Good to know

• Must be installed by a registered electrician, as it's wired to the heater and mains supply
• Only need the screen? We sell the Fenix and Xenio displays separately
• Only need the circuit board inside the box? Get in touch and we can source that too
