By connecting a DHW pump, instant hot water can be available
at the tap.
The DHW pump and the installation are field supply and the
responsibility of the installer.
For more information about connecting the recirculation
connection (for integrated DHW tank), see the installation
chapter.
Configuration
For more information, see the configuration chapter.
You can program a schedule to control the DHW pump via the
user interface. For more information, see the user reference
guide.

The DHW pump and the installation are field supply and 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 the configuration chapter.

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
5.5.1 Produced heat
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
Setup and configuration:
No additional equipment needed.
Only in case a booster heater is present in the system,
measure its capacity (resistance measurement) and set the
capacity via the user interface. Example: If you measure a
booster heater resistance of 17.1 Ω, the capacity of the
heater at 230 V is 3100 W.
