# Code Description
[9.8.7] N/A 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 only buffered in the storage tank (i.e.
heat up the storage tank).
▪ Yes : The extra energy from the photovoltaic
panels is buffered in the storage tank, and in
the space heating/cooling circuit (i.e. heat up
or cool down the room).
[9.8.8] N/A Limit setting kW
Restriction: Only applicable if:
▪ [9.8.4]= Smart grid .
▪ There is no pulse meter (power meter) for
photovoltaic
panels available ([9.A.2]
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.

functionality.
# Code Description
[9.9.1] [4-08] Power consumption control :
▪ 0 No : Disabled.
▪ 1 Continuous : Enabled: You can set one
power limitation value (in A or kW) to which
the system power consumption will be
limited for all the time.
▪ 2 Inputs : Enabled: You can set up to four
different power limitation values (in A or kW)
to which the system power consumption will
be limited when the corresponding digital
input asks.
