A quick guide to the five Fenix options

Which Harvia Fenix Is Right for You?

The choice is simpler than it looks. First identify whether you are controlling a standard electric heater or a Combi heater with a steamer. Then match the control unit to the heater output and electrical configuration.

Standard Electric Heater Choose FX30 or FX45 according to voltage, phase, and kW.
Combi + Steamer Choose the FX30C version matching the system's 240V or 208V configuration.
Display Upgrade Only Choose FX001XW only when upgrading a compatible existing Harvia system.
Standard electric control

Fenix FX30

Choose FX30 for compatible standard electric sauna heaters within these power limits.

240V · 1-Phase Up to 7 kW
208V · 3-Phase Up to 10.5 kW
Higher-output electric control

Fenix FX45

Choose FX45 when a compatible standard electric heater requires greater control capacity than FX30 provides.

240V · 1-Phase Up to 11 kW
208V · 3-Phase Up to 15 kW
Combi heater + steamer control

FX30C 240V

For compatible 240V Combi sauna systems where Fenix controls both sauna heating and the steamer or humidity function.

Configuration 240V
Maximum Rating Up to 12.7 kW
Combi heater + steamer control

FX30C 208V

For compatible 208V Combi sauna systems where both electric heat and humidity or steamer functions are part of the experience.

Configuration 208V
Maximum Rating Up to 10.8 kW
Interface upgrade

Fenix FX001XW Display Upgrade.

Choose this only when you already have a compatible Harvia control system and need the Fenix touchscreen interface. This is a display upgrade, not a complete FX30, FX45, or FX30C control package.

The easiest way to choose: standard electric heater means FX30 or FX45 based on your heater's voltage, phase, and kW. A Combi heater with steamer functionality uses the appropriate FX30C configuration. The FX001XW is for a compatible display upgrade only.

Built-in intelligence

Tailored to You.

Harvia Fenix helps you control sauna temperature and duration with precision. Its intelligent learning technology remembers how your sauna heats, adapts to support consistent performance, and includes ready-made heating profiles such as Mild, Cozy, and Hot. Each profile can also be personalized around the way you prefer to unwind, recover, or prepare for the day.

Always WiFi-connected

Ready Before You Arrive.

Every Fenix control unit comes WiFi-enabled by default, with no separate connectivity module required. Built-in access supports remote use through the MyHarvia app, allowing you to prepare the sauna before you step inside. Over-the-air updates also help keep the system current as the Fenix experience continues to evolve.

Fast Setup, Easy to Enjoy.

It can be recessed into the wall, mounted on the surface, or installed inside the sauna where compatible. Guided setup, QR-based WiFi pairing, and plug-and-play preparation help create a smoother path from installation to the first session.

From homes to hotels and beyond

Control for Every Setting.

From private home saunas to hotels, spas, gyms, retreats, and shared wellness spaces, Harvia Fenix adapts across a wide range of environments.

Do Your Thing. Your Sauna Can Prepare Itself.

Life does not need to pause while your sauna warms. With the MyHarvia app, Fenix brings the ritual closer to the rhythm of your day. Begin heating after a workout, while cycling home, or before the final moments of an evening practice. Check the sauna status, see when it will be ready, and arrive to warmth that has already been waiting for you. It is not simply remote control. It is the quiet luxury of having restoration prepared before you ask your body to slow down.
