6.5.1 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.
6.5.2 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 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.
Power supply layouts with power meters
In most cases
, one power meter that measures the entire system (compressor,
backup heater and hydro) is sufficient.
