The Harvia Xenio CX30C is a Wi-Fi digital sauna control unit for Harvia heaters up to 12.7 kW, supplied for 240V single-phase or 208V three-phase. The panel can be mounted inside the sauna or outside it. It is sold separately from the heater and is required for heaters supplied without built-in controls.
The Xenio CX30C is the combi version: it runs the heating elements and the integrated steamer on a Harvia Combi heater, with independent temperature and humidity setpoints. It cannot be used with a dry heater, and a dry-heater control cannot run a Combi.
- For up to 12.7kW heaters Works with Virta Combi Series WiFi connectivity for control and monitoring
- Touch control panel, surface-mounted or flush-embedded
- Wi-Fi for remote start and monitoring from the MyHarvia app
- Controls heater, lighting and fan from one panel

Heaters with controls built into the body — Harvia KIP-B, The Wall, Vega Compact and the Cilindro PC range — do not take a separate control unit.
- The power unit is hardwired between the supply and the heater by a licensed electrician; the panel and the temperature sensor are wired back to it to the lengths the installation manual gives.
- The temperature sensor mounts inside the hot room, on the wall above the heater, at the height the manual specifies. Sensor position changes how the room behaves more than any setting on the panel does.
Which Harvia heaters does the Xenio CX30C work with?
Harvia lists it for the Virta Combi series. Heaters with controls built into the body do not take a separate control unit.
Can the Xenio CX30C be mounted inside the sauna?
Yes — the panel is rated for installation inside the hot room as well as outside it. Most people still mount it outside, because the point of a separate control is starting the sauna before you walk in.
Will the Xenio CX30C run a standard dry heater?
No. This is the Combi version — it controls a heater and its integrated steamer with separate temperature and humidity setpoints. A Combi heater needs a Combi control, and a dry heater needs the standard version.
