5.4.3 Setup and configuration – DHW tank
▪ For large DHW consumptions, you can heat up the DHW tank
several times during the day.
▪ To heat up the DHW tank to the desired DHW tank temperature,
you can use the following energy sources:
▪ Thermodynamic cycle of the heat pump
▪ Anti-legionella heater
▪ Solar panels
▪ For more information about optimizing the energy consumption for
producing domestic hot water, see "8 Configuration" on page 50 .
5.4.4 Combination: Standalone DHW tank +
Solar panels
By connecting the DHW tank to solar panels, the DHW tank can be
heated by solar energy.
For installation instructions, see the installation manual of the solar
kit and addendum book for optional equipment.

▪ The DHW pump and the installation are field supply and the
responsibility of the installer.
▪ For more information about connecting the recirculation
connection: see "7 Installation" on page 29 .
Configuration
▪ For more information, see "8 Configuration" on page 50 .
▪ You can program a schedule to control the DHW pump via the

▪ The DHW pump is field-supplied and its installation is the
responsibility of the installer.
▪ The temperature of the DHW tank can be set to maximum 60°C. If
applicable legislation requires higher temperature for disinfection,
you can connect a DHW pump and heater element as shown
above.
▪ If applicable legislation requires disinfection of the water piping
until the tapping point, you can connect a DHW pump and heater
element (if needed) as shown above.
Configuration
The indoor unit can control DHW pump operation. For more
information, see
"8 Configuration" on page 50 .

▪ For the standalone DHW tank: If there is no electrical backup
heater in the space heating circuit, you must install a DHW pump
for tank preheating.
Configuration
The indoor unit can control DHW pump operation. For more
information, see
"8 Configuration" on page 50 .
5.5 Setting up the energy metering
▪ Via the user interface, you can read out the following energy data:
▪ Produced heat
▪ Consumed energy
