Our Controls
Easy to handle
We have been developing tailor-made sauna controls for more than 30 years and in third generation with a business partner and manufacturer from the bathroom industry. As a result, the controls are optimally adapted to our tailormade saunas and in the process achieve top results when it comes to effective energy management and low power consumption, as well as the shortest heating times. Particularly noteworthy is the extremely steady sauna climate: the very slight fluctuating sauna temperature is considered especially pleasant.
Your safety is important to us!
All KOERNER sauna controls are equipped with:
- Two or three sensor comfort measurement systems
- Temperature setting up to max. 115° C
- Safety shutdown by temperature limiter
- Safety stop for sensor defect
- Power-on timer
- Operating time limiter
As thoughtful and practical as the control technology proves to be, the operation is equally simple easy to understand. Each operating step is performed via display or light-emitting diodes.
