Resetting the overheat Protector (page 31 of the manual)
If the temperature of the sauna room becomes dangerously high, the overheat protector will permanently cut off the supply of the heater.
The overheat protector can be reset after the heater has cooled down.
 
Reset button location
The reset button is located inside the heater’s connection box (as attached). only persons authorised to carry out electrical installations can reset the overheat protector.
Prior to pressing the button, the cause of the fault must be found.

Are the stones crumbled and pressed together?

• Has the heater been on for a long time while unused?
• Is the sensor of the thermostat out of place or broken?
• Has the heater been banged or shaken?
