5.7 Avoiding retardation of boiling
At temperatures above 60 °C, the ultrasound is activated automat-
ically for 3 seconds every minute to mix the fluid to avoid retarda-
tion of boiling. This function cannot be switched off. You can
configure the system so that this function is always active when
the heating is switched on, even at temperatures below 60 °C.

Procedure
Hold down the button for setting the heating temperature and
press the on/off button to switch on the ultrasonic bath.
» As soon as the heating is switched on, the ultrasound is acti-
vated once per minute regardless of the temperature.
Information
– The device does not save the setting. The next time it is
switched off and back on again, the function for preventing
retardation of boiling will be active again from 60 °C.
