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.

ENGLISH

www.stiebel-eltron.com DHEConnect | DHETouch |63

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.
