OPERATION
Settings
ECO Dynamic (with single circuit operation)
This energy saving mode allows you to achieve maximum energy
efficiency through automatic dynamic matching to your draw-off
patterns.
ECO Dynamic mode works best if you always require comparable
volumes of hot water at the same time of day, regardless of the
day of the week.
ECO symbol flashes
The set temperature is automatically set imme-
diately to 60 °C.
When you select ECO Dynamic mode, the appli-
ance evaluates your draw-off times and quanti-
ties for a week. At this time, the appliance ini-
tially operates in ECO Comfort mode.
After analysing, the calculated mixed water vol-
ume is made available, subject to the day and
time. Up to 60 % of the cylinder content can be
drawn off before the appliance reheats. If the
currently available mixed water volume is not
sufficient for the expected draw-off, the entire
cylinder content is heated in good time to 60 °C.
If the draw-off times and volumes change, the
appliance analyses the changes and adjusts the
available mixed water volume as required.
You can select this mode in the menu (see chapter "Menu settings
/ Displaying and adjusting ECO mode").
Note
If you change the set temperature in ECO Dynamic mode,
the appliance switches automatically to ECO Comfort
mode.
4.2.2 Commercial mode
The heating contractor can adjust the appliance for commercial
applications, e.g. in doctors' practices or butchers' shops (see
chapter "Installation / Settings"). The set temperature is then ad-
justed manually. The ECO mode menu setting is not possible in
commercial mode.

4.2.3 Adjusted use of off-peak tariff periods
(reverse control with dual circuit operation)
This function is not enabled in the factory settings. The contractor
can switch on the appliance reverse control function (see chapter
"Installation / Settings").
This means that the appliance evaluates the cheap rate periods
of your power supply utility for 7 days to make the most of off-
peak times.
During the analysis, the appliance heats the cylinder content ready
for the start of the off-peak tariff period in case the set tempera-
ture is not reached.
The aim is to start heat-up at the right time so that the full cylinder
content heated to the set temperature is only available to you at
the end of the off-peak tariff period. This means less energy is
required to maintain the water at this temperature, i.e. the standby
energy consumption falls.
The appliance starts heating at the cal-
culated time.
Heat-up symbol appears.
Once heat-up has finished, the heat-up
symbol disappears.
If the set temperature is not reached, you can activate heat-up
with rapid heating if required (see chapter "Standard settings
/ Rapid heating") in the off-peak tariff period, even before the
automatic start time.
