Setting Up The Energy Metering; Produced Heat; Consumed Energy; Normal Kwh Rate Power Supply - Daikin Altherma ERLQ004-006-008CA Reference Manual

i Recirculation connection
▪ 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.
▪ To ensure a complete disinfection, you have to open the tapping
point.
WARNING
When opening the tapping point, the water temperature
can be up to 55°C.
Configuration
The indoor unit can control DHW pump operation. For more
information, see "8 Configuration" on
5.4

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.
5.4.1 Produced heat
INFORMATION
The sensors used to calculate the produced heat are
calibrated automatically.
▪ The produced heat is calculated internally based on:
▪ The leaving and entering water temperature
▪ The flow rate
▪ Setup and configuration: No additional equipment needed.
5.4.2 Consumed energy
You can use the following methods to determine the consumed
energy:
▪ Calculating
▪ Measuring
INFORMATION
You cannot combine calculating the consumed energy
(example: for backup
consumed energy (example: for outdoor unit). If you do so,
the energy data will be invalid.
Calculating the consumed energy
▪ Only applicable for EHVZ04+08.

heater) and measuring the
5 Application guidelines
▪ The consumed energy is calculated internally based on:
▪ The actual power input of the outdoor unit
▪ The set capacity of the backup 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).
Measuring the consumed energy
▪ Applicable for all models.
▪ Preferred method because of higher accuracy.
▪ Requires external power meters.
▪ Setup and configuration:
▪ For the specifications of each type of meter, see
data" on page 71.
▪ When using electrical power meters, set the number of pulses/
kWh for each power meter via the user interface. Consumed
energy data for EHVZ16 model will only be available if this
setting is configured.
INFORMATION
When measuring the electrical power consumption, make
sure ALL power input of the system is covered by the
electrical power meters.

Normal kWh rate power supply

General rule
One power meter that covers the entire system is sufficient.
Setup
Connect the power meter to X5M/7 and X5M/8.
