▪
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.
6.5.1 Produced heat
INFORMATION
The sensors used to calculate the produced heat are calibrated automatically.
INFORMATION
In the produced heat calculation:
▪
The energy losses in the piping between indoor and outdoor unit are NOT taken
into account.
▪
Besides the produced heat by the compressor, the produced heat by the backup
heater is added as well.
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.
▪
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 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
▪
The consumed energy is calculated internally based on:
-
The actual power input of the outdoor unit
-
The set capacity of the 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
backup heater (step 1).
