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 (comparison possible). On
commissioning, the height of the bars is zero for all months, as no in-
formation is available yet.
The scaling (in the example, 4000 kWh) adapts automatically to the
month's highest value.
Top right the total of the environmental yield since commissioning is
displayed (in the example: 13628 kWh).
Day, date, time as well as flow temperature, heating system pressure
16:49 1
and heat source pressure are displayed.
