4 Operation
Only if external passive cooling
is installed:
The symbol indicates that the heat
pump is in cooling mode. The cur-
rent heating flow temperature is
displayed under the symbol
(in the example 20 °C).
Energy yield display
The energy yield display graphically depicts 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 corre-
sponds to the yield for the month in the previous year (to
permit comparison). During commissioning, the height of
the bars is zero for all months, as no information is yet
available.
The scaling (in the example, 4000 kWh) adapts automati-
cally to the month's highest value.
In the top right, the total of the environmental yield since
start-up is displayed (in the example: 13,628 kWh).
