If room buffering is enabled, the extra energy from photovoltaic panels is buffered
in the DHW tank and in the space heating/cooling circuit (i.e. heat up or cool down
the room). With the room comfort setpoints (cooling/heating) you can modify the
maximum/minimum setpoints that will be used when buffering the extra energy in
the space heating/cooling circuit.
