system statuses at start-up and during operation. As soon as the diagnostic
software identifies an error, the sauna control unit switches the sauna heater off.

the flashing lights on the LED wheels c and f. Furthermore, the error number
is displayed with the help of the power level display 3. The number of LEDs on
it which are flashing indicates the error number. The following table describes
