3. Appliance description
The appliance switches on automatically as soon as you open the
hot water valve on the tap. When you close the tap, the appliance
switches off again automatically.
The appliance heats water as it flows through it. The DHW outlet
temperature can be variably adjusted. From a certain flow rate,
the control unit regulates the correct heating output, subject to
the temperature selected and the current cold water temperature.
The electronically controlled instantaneous water heater with au-
tomatic output matching maintains a consistent outlet tempera-
ture. It is irrespective of the inlet temperature, up to the maximum
output of the appliance.
If the appliance is operated with preheated water and the inlet
temperature exceeds the selected set temperature, the word "hot"
and the inlet temperature are displayed alternately, and the "hot"
LED flashes. The water is not heated further.
You can save and quickly call up different temperatures. With
the ECO function, the flow rate is limited to 3 preset levels. The
appliance is equipped with functions to permanently limit the
temperature (e.g. for childproofing). The backlight switches on
automatically as soon as water starts to flow through the appli-
ance or you make a change on the user interface. The backlight
switches off automatically 5 seconds after water stops flowing or
if no operation has been performed for 30 seconds.
You can set the temperature unit and operating lock individually.
Heating system
The bare wire heating system is enclosed within a pressure-tested
plastic jacket. The heating system with its stainless steel heater
spiral is suitable for hard and soft water areas and is largely in-
susceptible to scale build-up. The heating system ensures rapid
and efficient DHW provision.
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.
