Product Overview

The New Generation of Harvia Sauna Control

The Harvia Fenix FX30 WiFi Control Package represents Harvia’s latest control direction: a cleaner touchscreen interface, integrated WiFi functionality, mobile app support, and a smarter user experience designed around modern sauna ownership.

Harvia states that the Fenix control panel can be used to control the electric sauna heater, lighting, and ventilation. The panel features a 4.3” high-quality, temperature- and moisture-resistant glass screen and can be installed inside the sauna, bathroom, or living room depending on the installation requirements.

The Fenix FX30 is designed for electric heaters up to 7kW at 240V single-phase or up to 10.5kW at 208V three-phase, with the ability to extend output using a compatible Harvia LTY45 power unit when appropriate.

For customers comparing control options, the biggest difference is the user experience. Fenix looks and feels more current than older control panels, with a touchscreen interface that mirrors the MyHarvia 2 app experience and helps make daily sauna operation more intuitive.

Why You'll Love it!

Why Choose the Harvia Fenix FX30?

Harvia’s Latest Control Platform

Fenix is Harvia’s newest generation of sauna control panel, designed for a more modern and connected sauna experience than older mechanical or basic digital controls.

4.3” Glass Touchscreen

The sleek touchscreen gives the sauna a clean, premium control interface. Harvia describes the Fenix panel as a 4.3” high-quality, temperature- and moisture-resistant glass screen control panel.

MyHarvia App Support

Fenix supports remote control through the MyHarvia app and MyHarvia WebPortal when paired with the applicable MyHarvia control features. This allows supported sauna operation from a smartphone or tablet.

Controls Heater, Lighting & Ventilation

The FX30 can control your electric sauna heater as well as supported lighting and ventilation functions, helping simplify the sauna experience from one control platform.

Smarter Heater Performance

Harvia describes the Fenix interface as a modern, user-friendly system that continuously learns with AI and adapts to your electric heater’s performance.

Flexible Control Panel Placement

The glass panel can be surface-mounted or embedded, and Harvia notes it can be installed inside the sauna room, bathroom, or even a living room depending on the installation plan and manual requirements.

Designed for Select Harvia Heater Families

The FX30 is intended for compatible Harvia Club, Spirit, Cilindro, and Virta Series electric sauna heaters.

What Sets Fenix Apart from Older Harvia Controls?

Fenix Feels Like a Modern Smart Sauna Interface

Older sauna controls can be functional, but many feel dated compared to today’s smart-home expectations. The Harvia Fenix FX30 is different because it was built around a more modern control experience.

The 4.3” glass touchscreen gives the sauna a cleaner, more premium look. The interface is designed to match the MyHarvia 2 app experience, which makes the wall control and mobile control feel more consistent. The system can also manage more than just heater temperature, including supported lighting and ventilation functions.

Most importantly, Fenix is the newest Harvia control platform — the option I would position for customers who want the latest control technology, WiFi convenience, modern design, and a more intuitive sauna operation experience.

Compatible Harvia Heaters

The Harvia Fenix FX30-U1-U3-XC is designed for select Harvia electric sauna heaters, including:

Harvia Club Series
Harvia Spirit Series
Harvia Cilindro Series
Harvia Virta Series

Always confirm compatibility with your exact heater model before ordering. Some Harvia heaters have built-in controls and do not require an external control package, while others require a compatible external control system such as Fenix.

Final heater compatibility, breaker size, conductor size, grounding, sensor placement, control location, conduit, disconnect requirements, and installation method must always be confirmed by your licensed electrician using the official Harvia manual and local code.

Installation Location Notes

The Fenix FX30 control panel and the FX30 power unit have different placement considerations.

Harvia’s current product page says the Fenix glass control panel can be surface-mounted or embedded and installed inside the sauna room, bathroom, or even a living room. However, Harvia installation documentation also lists the power unit as on-wall and notes installation in the sauna: no for the FX30 power unit.

For outdoor saunas, this means your electrician should carefully review the manual and plan placement for the control panel, power unit, sensors, and wiring before installation. The power unit should be installed only where allowed by Harvia’s instructions and local electrical code.

Protect Your Sauna’s Electrical Equipment

Depending on your installation location, weather-resistant or waterproof enclosures may be needed for the heater control box, controller, or related electrical components. Please review the manufacturer manuals and consult your licensed electrician for proper placement and code-compliant installation.
