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.
▪ The produced heat is calculated internally based on:
- The leaving and entering water temperature
- The flow rate
▪ Setup and configuration: No additional equipment needed.
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).
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.
General rule
One power meter that covers the entire system is sufficient.
