Introduction
All you need to know about Fenix
Harvia Fenix is a modern, smart, and easy solution for controlling your sauna, whether at home or for professional use. The intuitive user interface, built-in WiFi connection, and flexible installation options make controlling your sauna easy: from temperature and humidity to lighting and ventilation, you can personalize your sauna with a single touch.
The Fenix & MyHarvia 2 mobile app represents the latest technology in electric heater control. Compared to the previous generation Xenio control, Fenix offers a significant number of new features and uses:
Key new features
- New intuitive user interface and easy guided setup
- Built-in WiFi and automatic OTA updates
- Remote control using a smartphone or Apple Watch
- Multiple customizable heating profiles
- Smart timer that learns how the heater works in any sauna room
- Guest mode
- Week timer function
- Harvia IO Web portal & remote diagnosis for error messages
- Compatible with previous generation XE and XW heaters
Remote control
You can remotely start the heater wherever and whenever you want - using your smartphone or Apple Watch*. In professional use, you can control multiple saunas using the Harvia IO Web Portal.
The visual design of the user interface is consistent regardless of whether the heater is controlled via the control panel, smartphone, or Apple Watch.
*Requires a separate data plan for the Apple Watch if you don't have your iPhone with you.

Licenses for remote use
Core & Control license - What is the difference between them?
Every product in the Fenix series has built-in WiFi connectivity. The products come with a MyHarvia Core license. If you want to use remote control, you need to upgrade your license to MyHarvia Control license. The upgrade is purchased directly in the MyHarvia app.
With the free Core license, you can remotely monitor the heater's operation, receive notifications related to heating, and view the sauna's usage history. The key difference between the Core and Control licenses is that Core does not include an option for remote start of the heater. See the comparison between licenses below:
All new products with Core include a free 3-month trial of the Control tier.
Pricing - Lifetime control license
A lifetime Control license costs 99€ as a one-time payment. The upgrade is purchased directly in the MyHarvia app.
Safety device
Heater remote control requires a safety device.
Door switch included with Fenix products is required for home use, unless the heater has its own integrated safety device.
SFE safety device is required for professional use (e.g., common saunas in apartment buildings, public saunas)
More information: Safety devices for electric heaters
Compatibility
Fenix product family is compatible for many purposes. Below you will find various options for purchasing new products or updating your existing products:
Buying a new heater for home use
Fenix heaters for home use (FC models) include all necessary parts in one package. The Spirit FC heater includes an integrated safety device, so you don't need a separate door sensor or other safety device for remote use.
The heaters are delivered with a MyHarvia Core license. If you want to use remote control, you need to upgrade your license to MyHarvia Control license. The upgrade is purchased directly in the MyHarvia app.
You can calculate the power requirement (kW) of the heater using the Harvia sauna calculator.
Buying Fenix control panel for my current heater
You can upgrade any current XE or XW heater to Fenix simply by replacing the control panel. No electrician* is needed for installation, as the control panel data cable does not need to be replaced. The same RJ10 data cable is compatible with both XE and XW models as well as Fenix.
Note: Fenix remote control functions are not compatible with the CX110 (CX110400) control unit!
Recommended option: Upgrade your current heater with the FX002XW accessory package
- FX002XW accessory package includes a Fenix control panel and door sensor for home remote use. *Please note that the installation of the door sensor requires a qualified electrician.
Second option: Upgrade the control panel only
- If you already have a safety device installed, or alternatively don't need remote control functions, choose the FX001XW accessory package (control panel only).
Both FX accessory packages include a Control license as standard.
Backward compatibility
Fenix is compatible with all XE and XW heaters equipped with a Xenio control panel. Older-generation Xafir and EE control panels are not compatible.
Note: Fenix remote control functions are not compatible with the Xenio CX110 (CX110400) control unit!
Buying a new heater for professional use
We recommend purchasing an E-model heater with a separate control unit for professional use.
E model heater for professional use
The difference between the E model and the standard model intended for home use is that all control electronics are located in a separate power unit outside the heater.
The Fenix separate control unit is compatible with almost any E model heater.
When selecting a control unit, consider the following
- Heater power (kW)
- Does the heater have a steam function
- Safety device:
The E model heater, control unit and safety device* are sold separately. If the E model heater is installed for home use, the door sensor supplied with the control unit is used as a safety device. *The safety device is only required for remote use - otherwise, it is not necessary.
You can calculate the power requirement (kW) of the heater using the Harvia sauna calculator. The control unit model is selected based on the power and/or features of the heater as follows:
Control unit FX110
- Maximum heater power 11 kW. Can be expanded to 28 kW with the LTY17 power unit
- IPX5 rating: Separate power unit can be placed in the sauna room
- SFE safety device must be purchased separately (professional use)
Control unit FX170
- Maximum heater power 17 kW. Can be expanded to 34 kW with the LTY17 power unit
- A separate power unit is placed in a dry space.
- SFE safety device must be purchased separately (professional use)
Control unit FX110C
- For heaters with steaming function (vaporizer)
- Maximum heater power 11 kW. Can be expanded to 28 kW with the LTY17 power unit
- IPX5 rating: Separate power unit can be placed in the sauna room
- SFE safety device must be purchased separately (professional use)
+ Safety device SFE
- Home use: a door sensor for home use is included in the sales package. No SFE safety device required.
- Professional use: SFE safety device is purchased separately.
- A safety device is also required when remote control is performed via potential-free tip data (on/off) instead of the MyHarvia app, for example, via home automation
+ Power extension unit LTY17/LTY17C
- Only required when heater power (kW) exceeds the maximum power of the control unit, or if the heater has 2 power groups (two supply cables)
- LTY17C only for Combi sauna heaters equipped with two separate steamer units.
Note: Fenix remote control functions are not compatible with the Xenio CX110 (CX110400) control unit!

Guest mode
Guest mode allows you to restrict or hide certain settings from the control panel view behind a PIN code. This feature is useful in facilities where sauna users can be granted access to limited functions.
Guest mode features
- Temperature limit (selected minimum and maximum values)
- Heater on-time limit
- Timer function enabled or disabled
- Access to settings menu enabled or disabled
Example of Guest mode use as shown in the image above: In a hotel room with a sauna, the heater settings are limited so that the customer can adjust the temperature between 60 and 80 degrees Celsius, and the heater's operating time (on-time) is permanently locked for two hours. Access to the settings menu is disabled with a PIN code.
How to enable Guest mode
- Activate Guest mode from the control panel settings and select the four-digit PIN code of your choice.
- The settings menu icon disappears from the control panel display.
How to disable Guest mode
- Press and hold the upper-left corner of the control panel until the PIN code view appears.
