Appliance description

You can adjust the DHW outlet temperature via the temperature
selector. From a flow rate of approx. 3 l/min and above, the control
unit regulates the correct heating output, subject to the tempera-
ture setting and cold water temperature.
Heating system
The bare wire heating system has a pressure-tested plastic casing.
The heating system is suitable for (both) soft and hard water and
is largely resistant to scale build-up. This heating system ensures
rapid and efficient DHW availability.
Note
The appliance is equipped with an air detector that large-
ly prevents damage to the heating system. If, during op-
eration, air is drawn into the appliance, the appliance
shuts down for one minute, thereby protecting the heat-
ing system.
4. Operation
The DHW outlet temperature can be adjusted in 3 stages.
2
1
1 Hand washbasin (approx. 35 °C)
2 Shower / bath (approx. 45 °C)
3 Kitchen sink (approx. 55 °C)
f Turn the temperature selector to the required position. f
Should the outlet temperature fail to reach the required level with
the tap fully open and the temperature selector set to maximum,
then more water is flowing through the appliance than can be
heated by the heating element.
f Reduce the flow rate at the tap. f
4.1

Recommended settings

Your instantaneous water heater offers maximum precision and
maximum convenience in DHW provision. Should you nonetheless
be operating the appliance with a thermostatic valve, we recom-
mend that you:
f Adjust the set temperature on the appliance to over 50 °C. f
Then set the required set temperature on the thermostatic
valve.
Saving energy
The following recommended settings will result in the lowest en-
ergy consumption:
- 35 °C for hand washbasins and bathtubs
- 55 °C for kitchen sinks
