Harvia Replacement Power Unit Control Box (No Screen)

This is the power unit, the metal control box that comes with a Harvia Fenix or Xenio control panel. It's the part that's wired to your heater and does the heavy lifting: it switches the heater's power, reads the sauna temperature sensor and talks to the touch screen out in the sauna. If the box has been damaged, or you've lost power to the heater and the circuit board isn't the only problem, this lets you replace just the box and keep the screen you already have. Screen not included. Which one do I need? Match the box to the model of your control panel (it's on the label inside the box and in the Harvia app): Fenix FX110 power unit Fenix FX110 WiFi Core, heaters up to 11 kW.
