Recirculation connection
▪ The DHW pump is field-supplied and its installation is the
responsibility of the installer.
▪ For the integrated DHW tank, 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 48
.
5.5
Setting up the energy metering
▪ Via the user interface, you can read out the following energy data:
▪ Produced heat
▪ Consumed energy
▪ You can read out the energy data:
▪ For space heating
▪ For space cooling
▪ For domestic hot water production
▪ You can read out the energy data:
▪ Per month
▪ Per year
INFORMATION
The calculated produced heat and consumed energy are
an estimation, the accuracy cannot be guaranteed.
5.5.1
Produced heat
INFORMATION
The sensors used to calculate the produced heat are
calibrated automatically.
▪ Applicable for all models.
▪ The produced heat is calculated internally based on:
▪ The leaving and entering water temperature
▪ The flow rate
▪ The power consumption of the booster heater (if applicable) in
the domestic hot water tank
