5 Application guidelines
h Domestic hot water OUT
i Recirculation connection
j Anti-legionella heater
▪ 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 70°C. If
the applicable legislation requires a 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
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 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 anti-legionella heater in the
domestic hot water tank
▪ Setup and configuration:
▪ No additional equipment needed.
▪ Measure the capacity (resistance measurement) of the anti-
legionella heater and set the capacity via the user interface.
Example: If you measure an anti-legionella heater resistance of
24Ω, the capacity of the heater at 230 V is 2200 W.
5.5.2 Consumed energy
You can use the following methods to determine the consumed
energy:
▪ Calculating
▪ Measuring
Installer reference guide
18
page 47.
INFORMATION
You cannot combine calculating the consumed energy
(example: for anti‑legionella heater) and measuring the
consumed energy (example: for outdoor unit). If you do so,
the energy data will be invalid.
Calculating the consumed energy
▪ The consumed energy is calculated internally based on:
▪ The actual power input of the outdoor unit
▪ The set capacity of the backup heater (if applicable) and anti-
legionella heater
▪ The voltage
▪ Setup and configuration: To get accurate energy data, measure
the capacity (resistance measurement) and set the capacity via
the user interface for:
▪ The backup heater (step 1 and step 2) (if applicable)
▪ The anti-legionella heater
Measuring the consumed energy
▪ Applicable for all models.
▪ Preferred method because of higher accuracy.
▪ Requires external power meters.
▪ Setup and configuration: When using electrical power meters, set
the number of pulses/kWh for each power meter via the user
interface.
INFORMATION
When measuring the electrical power consumption, make
sure ALL power input of the system is covered by the
electrical power meters.
5.5.3

Normal kWh rate power supply

General rule
One power meter that covers the entire system is sufficient.
Setup
Connect the power meter to X5M/5 and X5M/6.
Power meter type
In case of...
▪ Single-phase outdoor unit
▪ No backup heater or optional
backup heater supplied from a
single-phase grid
In other cases (i.e. a three-phase
outdoor unit and/or optional
backup heater connected to a
three-phase grid)
ERGA04~08DAV3(A) + EHVH04+08S23DAV
Use a... power meter
Single-phase
Three-phase
