7E00 Enable own energy consumption PV
Enabling utilisation of power generated on site from
the PV system.
Utilisation of power generated on site is active, when
all of the following criteria apply:
■ "Enable own energy consumption PV 7E00" is set
to "1" or "2".
At least 1 function, e.g. DHW heating, is enabled for
■
utilisation of power generated on site ("Enable own
energy consumption for DHW heating 7E11" set
to "1").
■ Over a certain period, the electrical output exported
to the grid is greater than the electrical output of the
heat pump.
"Standby mode" and "Holiday program" are disa-

bled.

7E02 Prop. of external current

Enabling for drawing power from the grid during utilisa-
tion of power generated on site: Applies only to com-
pressors with output-dependent control.
Value Meaning
"0" to The compressor must not be operated with
"9" power from the grid during utilisation of pow-
er generated on site.
If the output of the photovoltaic system is in-
sufficient for reaching the adjusted set tem-
peratures, the compressor output will be re-
duced accordingly.
Note
In order not to undershoot the minimum
speed, the compressor is operated with pow-
er from the grid if necessary.
"10" to If the output of the PV system is insufficient
"100" for reaching the adjusted set temperatures,
the compressor will draw a required propor-
tion of power from the grid.

Meaning
Utilisation of power generated on site is not
enabled.
Utilisation of power generated on site is ena-
bled. The energy meter is connected to the
heat pump control unit via Modbus. Con-
sumption data for the utilisation of power
generated on site is transferred directly from
the energy meter to the heat pump.
Utilisation of power generated on site is ena-
bled. Consumption data for the utilisation of
power generated on site is transferred to the
heat pump control unit via a Smart Home
system, e.g. Vitocomfort 200.
