Meaning
Excess electrical energy from the photovoltaic system is fed into the power grid.
The electrical power consumed by the heating system is taken into account (utilisa-
tion of power generated on site), with the exception of lag heat pumps in a heat
pump cascade.
Power from the grid is consumed in the building.
Consumers in the building and the heating system are not consuming electrical
■
energy.
or
The energy meter is faulty.
■
Electrical power measured by the energy meter in kW for each phase:
Positive value: Electrical power is fed into the power grid.
Negative value: Electrical power is drawn from the power grid.
Note
The polarity can be changed by a heat pump installer certified by Viessmann.

Once a week, the DHW cylinder is fully heated with power from the photovoltaic
system to "Set DHW temperature 2 600C" ("Enable own energy consumptn for
set DHW temperature 2 7E10").
Function not available
