PRODUCT DESCRIPTION
Control your sauna the smart way with the Harvia Fenix FX170 WiFi Core 17 kW Control Unit.
The Harvia Fenix FX170 WiFi Core is a modern and intelligent sauna control unit designed for electric sauna heaters up to 17 kW. It features a high-quality 4.3” Fenix glass touch-screen control panel, giving you precise control over temperature, timer settings, lighting, ventilation, and sauna operation.
With support for the MyHarvia mobile app, you can monitor your sauna from your smartphone, including sauna temperature, session statistics, and notifications. Full remote-control functionality is available with the MyHarvia Control Upgrade.
The Fenix system also features an intelligent user interface that continuously learns and adapts to your electric heater’s performance. As a result, it helps make sauna control more intuitive and efficient over time.
The control panel can be surface mounted or embedded and may be installed inside the sauna room, bathroom, or nearby living space where suitable. However, the FX170 power unit must be installed in an interior dry area, such as a changing room or outside the sauna room.
The FX170 power unit includes inputs for the temperature sensor, door sensor, heater safety device, lighting, and fan. This makes it a smart and reliable control system for residential sauna setups and professional sauna installations when the required additional safety device is used.
