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
- The power consumption of the booster heater (if applicable) in the domestic
hot water tank
▪ Setup and configuration:
- No additional equipment needed.
- Only in case a booster heater is present in the system, measure its capacity
(resistance measurement) and set the capacity via the user interface.
Example:
If you measure a booster heater resistance of 17.1Ω, the capacity of the heater
at 230 V is 3100 W.
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 and booster heater (if applicable)
- 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 and step 2) (if applicable)
- The booster heater
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.
