3. appliance description
The electronically controlled instantaneous water heater with
automatic output matching maintains a consistent outlet tem-
perature. This is irrespective of the inlet temperature, up to the
maximum output of the appliance.
dHw temperature
The DHW outlet temperature can be variably adjusted. The select-
ed temperature is displayed.
display backlighting
The display has white backlighting. During the draw-off process
or a temperature adjustment, backlighting is enabled.
temperature limit (child-proofing) / anti-scalding protection
The temperature limit (child-proofing) can be individually set
using the Tmax key. The selected temperature then limits the
setting range of the DHW outlet temperature.
The qualified contractor can also enable static anti-scalding pro-
tection from 43 °C for you (see chapter "Alternative installation
options / Anti-scalding protection"). The anti-scalding temperature
then functions as the upper limit for the DHW outlet temperature
and for the temperature limit (child-proofing).
Heating system
The heating system is suitable for hard and soft water areas; it
has low susceptibility to scale build-up. This system ensures rapid
and efficient DHW availability.
Note
The appliance is equipped with an air detector, which
largely prevents damage to the heating system. If, during
operation, air is drawn into the appliance, heating out-
put is shut down automatically for one minute, thereby
protecting the heating system.
