Default
Combi and Bi-O sauna control panels are designed for heaters with an integrated vaporizer. One panel lets you choose between a dry Finnish sauna and a humid mode and adjust the humidity. Finnish manufacturers use the name Combi, while EOS calls these heaters Bi-O. Read more
How does a Combi control panel differ from a standard one?
A Finnish (dry) sauna control panel only controls the heater. A Combi or Bi-O panel also controls the vaporizer and lets you set the humidity level. Humid mode usually runs at a lower temperature; the exact ranges are specified by the manufacturer.
How to choose a control panel for a Combi or Bi-O heater
Compatibility
The panel must be compatible with your heater and its vaporizer. Panels from the same manufacturer are usually the right fit.
Output
The panel's maximum switching capacity must be at least equal to your heater's output. Some panels can be extended with power extension units.
Features
Besides temperature and humidity, panels may also control lighting and ventilation or allow remote start via a mobile app.
Important: a Finnish (dry) sauna control panel is not suitable for a Combi or Bi-O heater, as it cannot control the vaporizer. Contact us with your heater model and we will check which panel fits.
