Upgraded Smart Sauna Control Technology - The Harvia Fenix FX45 is a sauna heater control unit with a touch control panel and Wi-Fi connectivity. Fenix provides a modern and intelligent user interface for controlling the heart of the sauna, the heater. The glass screen control panel is easy to install. The control panel with its Wi-Fi feature enables you to monitor and adjust your sauna settings remotely, ensuring it's always at the right temperature.
The Harvia Fenix touchscreen control panel is more than just a digital interface – it's an intelligent companion for your fitness routine. Using advanced AI learning technology, Fenix analyzes how your sauna heater performs and uses that data to optimize heating times for maximum efficiency. Simply set when you want your sauna ready for your post-workout recovery session, and Fenix automatically calculates the perfect start time.
Personalized Heating Profiles for Every Recovery Need
Fenix offers three scientifically designed heating profiles to match your recovery goals: Mild (gentle heat for active recovery days), Cozy (balanced warmth for standard sessions), and Hot (intense heat for deep muscle recovery). These pre-programmed sauna temperature profiles provide ready-made settings for different wellness experiences and can be fully customized or replaced with your personal favorites for consistent recovery results.
MyHarvia App – Remote Sauna Control
The updated MyHarvia sauna app complements the Fenix control panel with comprehensive remote control capabilities, detailed usage statistics to track your recovery routine, and proactive maintenance notifications to ensure optimal performance. With built-in WiFi connectivity, both the Fenix control panel and MyHarvia app receive automatic over-the-air software updates, ensuring your combi sauna control system stays current with the latest features and improvements.
