Daikin Altherma – Low temperature split
4P384974-1 – 2015.01
▪ 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 17.1Ω, the capacity of the heater at 230 V is
3100 W.
5.5.2
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 heater) and measuring the
consumed energy (example: for outdoor unit). If you do so,
the energy data will be invalid.
Calculating the consumed energy
▪ Only applicable for EHBH/X04+08 and EHVH/X04+08.
▪ The consumed energy is calculated internally based on:
▪ The actual power input of the outdoor unit
▪ The set capacity of the backup heater and booster 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)
▪ The booster heater
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
"14 Technical
data" on page 83
.
▪ When using electrical power meters, set the number of pulses/
kWh for each power meter via the user interface. Consumed
energy data for EHVH/X11+16 and EHBH/X11+16 models 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
In case of…
Use a… power meter
▪ Single-phase outdoor unit
▪ Backup heater supplied from a
single-phase grid (i.e. the
backup heater model is *3V or
*9W connected to a single-
phase grid)
Single-phase
In other cases (i.e. a three-phase
outdoor unit and/or a *9W
backup heater model connected
to a three-phase grid)
Three-phase

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.
▪ 230 V and 400 V three-phase grids are combined (very
uncommon), because of technical limitations of power meters.
▪ 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 20
for
an example with two power meters.
5.5.4
Preferential kWh rate power supply
General rule
▪ Power meter 1: Measures the outdoor unit.
