Description
Energy input display
Shows the energy extracted from the environment for each of the
12 months of the current year (black bar). White-filled bars represent
the future months of the year; the height of the bar corresponds to
the yield for the month in the previous year (to permit comparison).
On commissioning, the height of the bars is zero for all months, as no
information is available yet.
The scaling (in the example, 4000 kWh) adapts automatically to the
month's highest value.
The total amount of the environmental yield since start-up is dis-
played at top right (in the example: 13628 kWh).
The day of the week, the date, the time of day and also the flow tem-
