Starting once-only cylinder heating
Tap the following on-screen buttons:
1.
"One-off cylinder heating", to start once-only cyl-
inder heating by the boiler.
The DHW cylinder is heated to the selected set
DHW temperature.
To terminate cylinder heating early, tap "One-off
cylinder heating" again.

Energy situation of the heat generator

You can call up for the following information about the
energy situation and operating data of the heat gener-
ator:
Current heating output
■
■ Runtime (operating hours)
■ Electricity consumption
■ Gas consumption
Heating output, runtimes and consumption
1. Use / to call up the energy cockpit from the
standard menu.
2. Tap the heat generator to call up the current output
and the runtime.
To reset the runtime, see page 35.
3. Electricity consumption
Tap "Electricity consumption".
4. Tap the required period.
You can call up the following periods:

Note
The energy cockpit provides the system user with
information about the thermal and electrical consump-
tion of the heating system throughout the year. These
values are calculated taking account of the system
components used and user behaviour (e.g. runtime
and utilisation level). Due to system-specific parame-
ters (e.g. elevation of the installation or flue system
design), there may be discrepancies between the dis-
played and actual consumption values.
To improve the accuracy of the display, we recommend
that the system user enters the calorific value, gas cor-
rection factor and gas meter readings. Seasonal envi-
ronmental conditions and other factors may neverthe-
less continue to cause discrepancies. Therefore, it has
to be noted that the displayed values are not deter-
mined using measuring equipment but are only calcu-
lated. The energy cockpit is intended to visualise con-
sumption to date and is useful for highlighting
increased or decreased consumption in specific com-
parison periods. It cannot be used as a reliable basis
for billing.
To enter additional data, see page 20.
5. Tap the diagram for a period (e.g. day). The elec-
tricity consumption for this period is displayed as a
numerical value.
6. Gas consumption
Tap "Gas consumption".
