The Harvia Fenix FX45 is a WiFi sauna control unit with a 4.3-inch glass touchscreen panel, designed to run electric sauna heaters up to 11 kW at 240 V or up to 15 kW at 208 V, along with lighting and ventilation. Remote operation runs through the MyHarvia app, and the panel's interface matches the app, so settings look the same locally and remotely.
The touchscreen can be surface-mounted or recessed in a bathroom, a living area or another indoor space. Ready-time scheduling, preset and user-created profiles, child lock, door sensor support and over-the-air updates are built in. The SP232 / SP232M heater sensor is included, and the unit is UL certified for the U.S. market.
