thermal system, observe the following information:
- The DHW temperature may exceed the set tempera-
ture or a set temperature limit.
- The dynamic anti-scalding protection between the
appliance and a wireless remote control may not be

WARNING Injury
!
The appliance may be used by children aged3 and older
and persons with reduced physical, sensory or mental
capabilities or a lack of experience and know-how, provided that they are supervised or they have been instructed 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 appliance or perform user maintenance unless they are
supervised.
WARNING
!
For continued safety of this appliance it must be installed, operated and maintained in accordance with
the manufacturer's instructions.
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-domestic 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 inappropriate. 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
If using preheated water, the tap can reach a temperature of up to 50°C during operation. There is a risk of
scalding at outlet temperatures in excess of 43 °C.
CAUTION Burns
If children or persons with limited physical, sensory or
mental capabilities use the appliance, set a temperature
limit. Once set, check the temperature limit is working
correctly.
If a permanent and unchangeable temperature limit is
required, have the internal anti-scalding protection set
by a qualified contractor.
WARNING
!
This appliance must only be installed in accordance
with the acceptable plumbing configurations specified
in these instructions. Failure to do so may result in conditions where delivery temperature control is inadequate.
Material losses
!
The user should protect the appliance and its tap against
frost.
2.3 Test symbols
See type plate on the appliance
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 set temperature is adjustable. Upwards of a certain flow rate, the control unit
selects the required heating output, subject to the temperature
selected and the cold water temperature.
The electronically controlled instantaneous water heater with automatic output matching maintains a consistent outlet temperature. 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 temperature, the word "hot"
and the inlet temperature are displayed alternately, and the "hot"
LED flashes. The water is not heated further.

OPERATION
Settings and displays
You can store different set temperatures and call them up quickly.
With the ECO function, the flow rate is limited to 3 preset levels.
The appliance has setting options for a temperature limit (Tmax
function, user) and internal anti-scalding protection (qualified
contractor). The backlight switches on automatically as soon as
water starts to flow through the appliance or you make a change
on the user interface. The backlight switches off automatically
after water stops flowing or if no action is performed.
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 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, during operation, air is drawn into the appliance, the appliance
shuts down for one minute, thereby protecting the heating system.

is set to maximum, then more water is flowing through
the appliance than can be heated by the heating system
(appliance working at maximum output).

the required temperature is achieved.
4.4 Temperature limit via internal anti-scalding
protection (qualified contractor)
If required, the qualified contractor can set a permanent temperature limit, for example in nurseries, hospitals,etc.

flashes continually once the set temperature has been reached.

OPERATION
Settings and displays
4.5 Temperature limit Tmax (user)
The temperature limit allows you as a user to restrict the adjustable set temperature at the appliance to a maximum value.
Your qualified contractor can set an additional temperature limit
for anti-scalding protection. This temperature then dictates the
upper limit of the setting range for the temperature limit function.
4.5.1 Enabling the temperature limit
f Press and hold buttons "1" and "2" for longer than 5seconds,
until "Tmax" and the temperature display flash.
f Select a temperature limit.
10seconds after completing the setting, the menu item will disappear automatically.
If the high limit safety cut-out is enabled, "Tmax" is continuously
displayed.
Check that the upper temperature limit has been correctly applied.
4.5.2 Disabling the temperature limit
f Disable the high limit safety cut-out by pressing and holding
buttons "1" and "2" for longer than 5seconds.
4.6 Allocating temperature memory buttons
Memory buttons "1" and "2" can each be assigned a required
temperature.
f Select the required temperature.
f To store the required temperature, press and hold button "1"
or "2" for longer than 3seconds. The selected temperature
flashes once to confirm.

4.9 Inlet temperature information
If the appliance is operated with preheated water and the inlet
temperature exceeds the selected temperature, the word "hot"
and the inlet temperature are displayed alternately, and the "hot"
LED flashes.
4.10 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 recommend that you:
f Set the temperature at the instantaneous water heater to the
maximum temperature. Then set the required set temperature on the thermostatic valve.
Saving energy
The following recommended settings will result in the lowest energy consumption:
If required, the qualified contractor can set a permanent temperature limit, for example in nurseries, hospitals,etc.
Limiting it in this way prevents water from flowing out of the
appliance at temperatures which could cause injury.
f To call up the menu, press and hold the ECO button for
longer than 5seconds.
f To select, turn the temperature selector.
f Press the ECO button once more.
f To quit the menu, press and hold the ECO button for longer
than 5seconds.
The menu switches off automatically if no operation has been
performed for 30seconds.
Note
To call up the menu when the operating lock is enabled,
press and hold the ECO button for longer than 10seconds.

INSTALLATION
7. Safety
Only a qualified contractor should carry out installation, commissioning, maintenance and repair of the appliance.
7.1 General safety instructions
We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the appliance
are used.
Material losses
!
Observe the maximum inlet temperature. Higher temperatures may damage the appliance. You can limit the
maximum inlet temperature by installing a central thermostatic valve.
CAUTION Burns
If operating with preheated water, e.g. if using a solar
thermal system, observe the following information:
- The DHW temperature may exceed the set tempera-
ture or a set temperature limit.
- The dynamic anti-scalding protection between the
appliance and a wireless remote control may not be
effective.
f In such cases, limit the temperature with an up-
stream central thermostatic valve.
Note
Programming unit displays and selected settings are retained following a power failure.
If you cannot remedy the fault, contact your qualified contractor.
To facilitate and speed up your request, provide the number from
the type plate (000000-0000-000000).
