Produced Heat; Consumed Energy; Normal Kwh Rate Power Supply - Daikin EWAQ006BAVP Installer's Reference Manual

5 Application guidelines
▪ 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.
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.
▪ Applicable for all models.
▪ 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
▪ The consumed energy is calculated internally based on:
▪ The actual power input of the outdoor unit
▪ The set capacity of the optional 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 optional backup heater (step 1 and
step 2).
Measuring the consumed energy
▪ Preferred method because of higher accuracy.
▪ Setup and configuration:
▪ Requires option box EK2CB07CAV3.
▪ Requires external power meters.
▪ 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.

heater) and measuring the
5.4.3

Normal kWh rate power supply

General rule
One power meter that covers the entire system is sufficient.
Setup
▪ Install control box EKCB07CAV3 and option box EK2CB07CAV3.
▪ Connect the power meter to X2M/7 and X2M/8 of option box
EK2CB07CAV3.
Power meter type
In case of...
Backup heater supplied from a
single-phase grid (i.e. the backup
heater model is *3V or *9W
connected to a single-phase grid)
In other cases (i.e. a *9W backup
heater model connected to a
three-phase grid)

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.
