You can use the following methods to determine the consumed energy:
▪ Calculating
▪ Measuring
INFORMATION
You cannot combine calculating the consumed energy (example: for the backup
heater) and measuring the consumed energy (example: for the rest of the 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 indoor unit
- The set capacity of the backup heater
- The voltage
▪ Setup and configuration: None.
Measuring the consumed energy
▪ 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.
In most cases, one power meter that measures the entire system (compressor,
backup heater and hydro) is sufficient.
Power meter
1 Entire system
In case of the following combination, you need 2 power meters:
▪ Dual cable power supply (= split power supply)
▪ + Preferential kWh rate power supply with separate normal kWh rate power
supply

1 Hydro and backup
heater
2 Compressor
(1) 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.
