Dynamic anti-scalding protection

With dynamic anti-scalding protection, once the user selects a
temperature at the appliance programming unit or the wireless
remote control, they then automatically have priority for setting
the maximum temperature. This priority is available for 2 min-
utes or until 2 minutes after the end of the current draw-off.
After this, the priority is automatically disabled.
Whilst the priority is enabled, the temperature can be reduced
or increased to a maximum of 43 °C by other programming
units.
