on the installation and configuration on
the user interface, we distinguish its
functionality.

of
the
domestic hot water pump when it
should run. Control of this pump is
possible through the indoor unit.

preheating. Necessary for EHBH_CBV
without backup heater. It runs when
the domestic hot water tank is being

and 3. It runs when the disinfection
function of the domestic hot water tank
is running, or when the domestic hot
