WHAT HARVIA ACCESSORIES ARE FOR

Harvia accessories are the components that make a heater system usable day to day—especially the control layer. A compatible control panel sets temperature and time, supports safe operation, and (in some setups) enables remote start and scheduling through Wi‑Fi sauna controls. The key is compatibility: controls and power extension boxes must match the heater series and electrical service (for example, certain commercial installations use 208V/3‑phase configurations).

Control Panels, Power Extensions, and Why They Matter

Many Harvia heaters require a specific control type and, in some cases, a separate power extension box. Think of it as a simple system:

Control panel = the interface you use (temperature, time, session control)

Power extension box = the hardware that supports compatible higher‑output heaters and wiring requirements

Before you buy, confirm: heater model name + kW, voltage, and whether the install is residential or commercial. If you are still shopping for heaters, start at Harvia Sauna Products or Harvia Electric.

When to Choose Wi-Fi Sauna Controls?

If you want the sauna warming before you arrive home, look for Harvia Xenio configurations that include Wi‑Fi functionality. Always confirm local code requirements and safe-use guidelines for remote start functionality.

COMPATABILITY CHECKLIST:

• Step 1: Identify heater model + kW (from the heater product page).
  
• Step 2: Confirm electrical service (240V 1‑phase vs 208V/3‑phase where applicable).
  
• Step 3: Select the required Harvia Xenio controls configuration.
  
• Step 4: Add the required power extension box (if specified) and confirm sensor/installation notes.

FAQs

Are Harvia controls universal?

No—Harvia Xenio controls and power extension components must match your heater model and electrical service. Always confirm compatibility on the product page.

Do I need a power extension box?

Some installations require a power extension component (like an LTY unit) depending on heater output and wiring requirements. Review the product listing and your heater manual.
