Harvia Fenix FX45 WiFi Digital Sauna Control

This is the Harvia Fenix WiFi control for the same heaters we already map to Xenio CX45 — Club K12.5G / K15G, Cilindro PC80E / PC90E / PC110E, Spirit SP80E, Virta HL80E / HL90E / HL110E. The heater is sold separately. Virta Pro HL160E is 16 kW — over Harvia’s FX45 11 kW (240V) / 15 kW (208V) cap — so we do not auto-offer Fenix there. Pick Xenio or Fenix on a heater page, not both.

FAQ

Is a heater included?
No. Control only.

Xenio or Fenix?
Pick one. Do not add both.

Virta Pro 16 kW?
Harvia FX45 max is 11 kW at 240V / 15 kW at 208V. HL160E is 16 kW — we do not auto-offer this SKU there. Email us.

Virta Combi?
No. That is FX30C, 1-phase only on this shop.

Can I check out?
Yes. Email hello@selfcaresaunas.com if Club 12.5 / 15 is 240V 1PH — that is over the 11 kW FX45 1PH cap.

A licensed electrician reads the nameplate and the manufacturer manual — we do not guess breaker size.
