Description
The Harvia Fenix FX001XW is a 4.3 inch glass touchscreen control panel with built-in WiFi. Harvia designed it as a plug-and-play upgrade for Harvia Xenio control panels, so you can replace an existing Xenio panel and keep the power unit. It controls temperature, humidity, the heater, ventilation and lighting, and learns your heater's heating curve for a smart timer.
