Matching the cylinder volume that can be heated up (only for
the Vitocal 242, if required)
If solar collectors are connected to the
equipment, we recommend you limit
the cylinder volume that can be
heated by the heat pump in favour of
heating by the solar collectors.
If this is not required, we recommend
the adjustment of the switching times
for DHW heating, so that the total
cylinder volume will only be enabled
for heating in the afternoon of each
day.
