Description
A Virta Combi heats the stones and produces steam, so it needs a control that handles both — the standard Cilindro/Virta control will not run it. This is that control, in the two Harvia lines.
Xenio or Fenix?
Xenio is the established line with a touch panel and a fixed program. Fenix is the current generation: a glass screen, ventilation control, and software that learns how your heater behaves and adapts to it. Both give you Wi-Fi control from your phone, the same 104–194 °F range and a pre-set start up to 12 hours ahead.
1-phase or 3-phase?
This follows your electrical supply, not your preference — check with your electrician before ordering. The 3-phase versions (208 V) handle heaters to 10.8 kW; the Xenio 1-phase runs on 240 V and the Fenix 1-phase covers up to 12.7 kW, which is the widest of the four.
Each unit includes the panel, temperature sensor and power unit. If a sensor came with your heater, fit that one following the heater’s manual.
