Operation – for users and qualified contractors

3. Equipment description

The appliance heats water as it flows through it. The
DHW outlet temperature can be infinitely adjusted at
the temperature selector. From a certain throughput, the
control unit regulates the correct heating output, subject to
the temperature selected and the cold water temperature.
The throughput is automatically reduced by the flow
regulator valve when supply temperatures are low and
the selected outlet temperature is high. This ensures
that the required temperature can be achieved reliably.
An ERROR is displayed if the appliance is operated with
preheated water above 45 °C.
Temperature selector
You can infinitely adjust the required temperature by
turning the rotary selector. The adjusted temperature is
shown on the display. The available temperature range
is specified in the chapter "Specification".
Memory keys 1 and 2
These keys enable you to quickly select two different
temperatures. You can determine these temperatures.
ECO key
This key enables you to switch the ECO function ON and
OFF. Switching the ECO function ON illuminates a green
LED below the key. In addition the ECO symbol appears
on the display.
The ECO function limits the flow rate to the ECO
throughput and sets the preselected ECO temperature.
You can match both values via this key.
Note
Any temperature adjustment on the appliance (with
temperature selector or via the memory keys) results
in the ECO function being cancelled. If required you
may then have to restart the ECO function.
If the temperature is selected via the wireless remote
control, the ECO function will also be restarted
automatically after the draw-off event has been completed.
INFO menu
You reach the INFO menu by pressing the ECO key,
where you can set comfort functions individually and/or
scan values (see chapter "Selecting ECO"): The ECO key
also enables you to determine the display brightness and
the orientation light.
You call up the setting options by holding down the ECO
key longer than three seconds.
If you now keep pressing the ECO key, you will reach the
respectively next function.
Once you have called up the required function, make your
function adjustments by turning the rotary temperature
selector.
Remote control via wireless remote control
With the wireless remote control you can influence the
appliance temperature from a distance (for example from
the kitchen sink).
The wireless remote control features four keys (38 °C
and 55 °C permanently set; + and - adjustable in steps
of 0.5 °C) for temperature selection. The transmission of
signals to the appliance is indicated by the red LED on
the wireless remote control illuminating. The transmitter is
waterproof and can be used whilst showering or bathing.
With the appliance in ECO mode, the ECO function is
suspended for the next draw-off event if a key on the
wireless remote control is pressed. Two minutes after
drawing has ceased, the appliance is reset to ECO mode.
In standard mode, a constant temperature setting can
be achieved via the wireless remote control (see chapter
"Wireless remote control key").

Dynamic anti-scalding protection
The appliance is equipped with dynamic scalding
protection. The user that selects a temperature first, either
at the appliance or at the remote control, determines the
temperature for the next draw-off event. No other user
can increase the temperature above 43 °C within the next
two minutes, during the draw-off event, or for two minutes
after the event.
Child-proof system
You can set the appliance to a maximum temperature (see
chapter "Start childproofing").
Wellness comfort function
You can permanently select the Wellness comfort
function, which reduces the temperature by 10 °C after
three minutes' draw-off and raises it again 10 seconds
later. After a further 10 seconds, the temperature is
again reduced by 10 °C, and then raised after another
10 seconds (see chapter "Setting Wellness comfort
functions"). These temperature changes continue until
the draw-off event ends.
Automatic water volume control
You can select an automatic water volume control that
reduces the throughput to approx. 4 l/min after a specified
volume has been drawn off (see chapter "Setting automatic
water volume control"). That way you can influence the
amount of water drawn as well as the duration of a shower.
The selected automatic water volume control applies only
to the next draw-off event.
Display backlighting
The appliance display is backlit. If you set temperatures
up to 42.5 °C, the backlighting illuminates in blue; at
temperatures from 43.0 °C, the colour of the display
changes to red.
The display backlighting is switched ON as soon as
you press any key, turn the rotary temperature selector,
or if water flows through the appliance with a greater
throughput than the start volume.
If no water is drawn off or the appliance is not operated for
30 seconds, the background lighting switches off (only if a
deactivated orientation light has been selected).
The brightness is dimmed if draw-off continues longer
than 15 minutes (Reduction only with the setting > 20 %).
You can adjust the brightness individually for red and blue
in five stages (see chapter "INFO menu settings").
Orientation light
The orientation light then lights up with the intensity of the
set background lighting.
