4.4 Further functions
4.4.1 Dynamic anti-scalding protection
The appliance is equipped with dynamic anti-scalding protection.
The user who is first to select a temperature on the appliance or
via the wireless remote control sets the temperature for the next
draw-off. No other user can increase the temperature above 43°C
in the following two minutes or during a draw-off or for two min-
utes following the end of a draw-off.
4.4.2 Anti-scalding protection
The qualified contractor can permanently limit the temperature
(see chapter "Troubleshooting/ Customer service mode"). This
prevents water from flowing out of the appliance at temperatures
which could cause injury.
4.5 Recommended settings

ergy consumption:

Thermostatic valve
If the appliance is being operated with a thermostatic valve, we
recommend setting the temperature on the appliance to maximum
(temperature selector set to 60°C). You can then select the required
temperature at the thermostatic valve.
