the bath has cooled down (see also chapter 8).

The electronic over-temperature protection controls the temperature limit (actual bath temperature

may not exceed the given temperature by 2 °C for more than 2 minutes), the heating rate (actual

temperature may not rise by more than 5 °C during 5 seconds) and the function of the temperature

sensor.
