▪
No
▪ Yes
Restriction: Only applicable in case of room
thermostat control, and if [9.8.4]=Smart grid.
To set if room buffering will be enabled.
Enable room buffering:
▪ No: The extra energy from the photovoltaic
panels is NOT buffered in space heating circuit.
▪ Yes: The extra energy from the photovoltaic
panels is buffered in the space heating/cooling
circuit (i.e. heat up or cool down the room).
Limit setting kW
Restriction: Only applicable if:
▪ [9.8.4]=Smart grid.
▪ There is no pulse meter (power meter) for
photovoltaic panels
Electricity meter 2 = None)
Normally, when a pulse meter is available, the
following happens:
▪ The pulse meter measures the power
produced by the photovoltaic panels.
▪ The unit limits its power consumption during
the Smart Grid's "Recommended ON" mode to
only use the power provided by the
photovoltaic panels.
However, when the pulse meter is not available,
you can still limit the unit's power consumption
using this setting (Limit setting kW). This
prevents overconsumption and thus requiring
the use of power from the grid.
