Note
The consumption figures displayed in the energy cock-
pit are not based on metering equipment but instead
are computed values. The calculation takes into
account the existing system components and the user
behaviour (e.g. operating time and utilisation level).
Depending on system-specific parameters (e.g. instal-
lation altitude and type of flue system), differences
may arise between the displayed (computed) and
actual consumption values.
Due to seasonal climate conditions and other factors,
further discrepancies are possible. The Energy cockpit
serves to visualise previous energy flows. It can show
increases and decreases in consumption within spe-
cific comparative periods. It cannot be used as a bind-
ing basis for billing.
Electrical output of the fuel cell module
Electrical output is influenced by the gas quality and
the geodetic head. Electrical output is also reduced by
a decrease in the fuel cell module’s electrical efficiency
over time.
The fuel cell module is operated with constant heat
input (gas input) and constant overall efficiency. This
means that the ratio of electrical output to heating out-
put changes over the service life. As the overall output
remains constant and electrical output decreases over
the service life, heating output increases.
Heating output, operating times and consumption
Tap the following on-screen buttons:
1. If necessary, for the home screen
2.
3. For example in "Gas consumption history"
4. Required period:
■ Current month
■ Last month
■ Current year
■ Last year
Gas consumption is shown as a graph.
5. Period in diagram (day of the week or month)
The gas consumption for that period is displayed
numerically.
Energy statement for power generation and power consumption
The current power generation and power consumption
data can be checked.
Tap the following on-screen buttons:
1. If necessary, for the home screen
2. for the energy statement
3. for the required period:
■ Current month
■ Last month
■ Current year
■ Last year
Energy statement in conjunction with power stor-
age unit:
The data displayed for power consumption and power
export does not differentiate between power from the
power storage unit and power from the public grid.
