2. Safety
2.1 Intended use
This appliance is suitable for heating domestic hot water or for
reheating preheated water. The appliance can supply one or more
draw-off points.
Water will not be reheated if the maximum inlet temperature for
reheating is exceeded.
The appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in non-do-
mestic environments, e.g. in small businesses, as long as it is
used in the same way.
Any other use beyond that described shall be deemed inappro-
priate. Observation of these instructions and of the instructions
for any accessories used is also part of the correct use of this
appliance.

2.2 General safety instructions
CAUTION Burns During operation, the tap can reach temperatures in ex-
cess of 60 °C.
There is a risk of scalding at outlet temperatures in ex-
cess of 43 °C.
CAUTION Burns If operating with preheated water, e.g.from a solar ther-
mal system, the DHW temperature may vary from the
selected set temperature.
!WARNING Injury
The appliance may be used by children aged3 and older
and persons with reduced physical, sensory or mental
capabilities or a lack of experience and know-how, pro-
vided that they are supervised or they have been in-
structed on how to use the appliance safely and have
understood the potential risks. Children must never play
with the appliance. Children must never clean the ap-
pliance or perform user maintenance unless they are
supervised.
Where children or persons with limited physical, sensory or men-
tal abilities are allowed to use this appliance, we recommend a
permanent temperature limit. The following limitation options
are available:
- user adjustable: "MAX" temperature limiting/ childproofing,
- qualified contractor adjustable: "Internal anti-scalding
protection".
!Material losses
The user should protect the appliance and its tap against
frost.
Note The mini wireless remote control has a lithium button
cell as battery for the power supply.
Remove spent batteries. Leaking batteries cause dam-
age which is excluded from any warranty. Never use re-
chargeable batteries.
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. You can adjust the
DHW outlet temperature via the touchscreen, via the Touch wheel
or via the mini wireless remote control. From a certain flow rate,
the control unit regulates the correct heating output, subject to
the temperature selected and the current cold water temperature.

OPERATION
Appliance description
This appliance with full electronic control and output matching
keeps the outlet temperature constant. The water is heated by
the electronic control unit with motorised valve to precisely the
selected temperature. This occurs regardless of the inlet tem-
perature.
If the appliance is operated with preheated water and the inlet
temperature exceeds the chosen set temperature, a warning mes-
sage appears on the display. The water is not heated further.
You can save and quickly call up different temperatures. The ECO
function limits the flow rate. The appliance has childproofing
functions, a wellness shower program, automatic water volume
control, dynamic anti-scalding protection, and permanent tem-
perature limiting. The backlight switches off automatically with
no intervention (user adjustable switch off time). As soon as water
flows through the appliance, or you make a change on the dis-
play or mini wireless remote control, the backlight switches on
automatically.
Prerequisites for use of extended functions (weather data, in-
ternet radio, app-based operation) with “DHEConnect”: WLAN
802.11, broadband internet connection, registration with email
address, terms of use and data protection consent agreement
(www.stiebel-eltron.com/terms-of-use/dhe).
The "DHE Connect" appliance has an integrated loudspeaker.
Alternatively, an external Bluetooth®loudspeaker can also be
used. In addition, it is also possible to output music from a mobile
terminal device to the integrated loudspeaker in the DHEConnect.
Heating system
The bare wire heating system is enclosed within a pressure-tested
plastic jacket. The heating system with its stainless steel internal
indirect coil is suitable for hard and soft water areas and is largely
insusceptible to scale build-up. The heating system ensures rapid
and efficient DHW provision.
Note
The appliance is equipped with an air detector that
largely prevents damage to the heating system. If, dur-
ing operation, air is drawn into the appliance, the ap-
pliance shuts down for one minute, thereby protecting
the heating system.

- "OFF" = heating system switched off
Dynamic anti-scalding protection
With the dynamic anti-scalding protection, after selecting a tem-
perature on the appliance or wireless remote control, the user has
automatic priority for maximum temperature setting. The priority
is active for 2minutes or until 2 minutes after the current draw-off
ends. After this, the priority is automatically disabled.
During the priority period, you can reduce the temperature or
increase it to a maximum of 43°C using other wireless controls.
Internal anti-scalding protection
If desired, your qualified contractor can set a permanent tem-
perature limit; forexample in nurseries, hospitals, and so on.
This prevents the flow of water at scalding temperatures from
the appliance.
