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.
▪ The produced heat is calculated internally based on:
▪ The leaving and entering water temperature
▪ The flow rate
▪ Setup and configuration: No additional equipment needed.
5.5.2
Consumed energy
Measuring the consumed energy
▪ Requires external power meters.
▪ Setup and configuration:
▪ For the specifications of each type of meter, see
"14 Technical
data" on page 66
.
▪ When using electrical power meters, set the number of pulses/
kWh for each power meter via the user interface. Consumed
energy data 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.
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/7 and X5M/8.
Power meter type
Use a three-phase power meter.

Exception
▪ You can use a second power meter if:
▪ The power range of one meter is insufficient.
▪ The electrical meter cannot easily be installed in the electrical
cabinet.
▪ Connection and setup:
▪ Connect the second power meter to X5M/9 and X5M/10.
▪ In the software the power consumption data of both meters is
added so you do NOT have to set which meter covers which
power consumption. You only need to set the number of pulses
of each power meter.
▪ See
"5.5.4 Preferential kWh rate power supply" on page 16
for
an example with two power meters.
5.5.4
Preferential kWh rate power supply
Setup
▪ Connect power meter 1 to X5M/7 and X5M/8.
▪ Connect power meter 2 to X5M/9 and X5M/10.
Refer to
"6.4.3 Overview of electrical connections except external
actuators" on page 22
.
5.6
Setting up the power consumption
control
▪ The power consumption control:
▪ Allows you to limit the power consumption of the entire system
(sum of indoor unit and backup heater).
▪ Configuration: Set the power limitation level and how it has to
be achieved via the user interface.
▪ The power limitation level can be expressed as:
▪ Maximum running current (in A)
▪ Maximum power input (in kW)
▪ The power limitation level can be activated:
▪ Permanently
▪ By digital inputs
