a Cold water IN
b Hot water OUT (shower (field supply))
c DHW pump (field supply)
d Heater element (field supply)
e Non‑return valve (field supply)
▪ The DHW pump is field-supplied and its installation is the responsibility of the
installer. For the electrical wiring, see
"9.3.5 To connect the domestic hot water
pump" [ 4 118].
▪ If the applicable legislation requires a higher temperature than the maximum
tank setpoint during disinfection (see [2-03] in the field settings table), 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
"10 Configuration" [

6.5 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.
6.5.1 Produced heat
INFORMATION
The sensors used to calculate the produced heat are calibrated automatically.
INFORMATION
If glycol is present in the system ([E‑0D]=1]), then the produced heat will NOT be
calculated, nor will it be displayed on the user interface.
▪ The produced heat is calculated internally based on:
- The leaving and entering water temperature
- The flow rate
