INFORMATION
You cannot combine calculating the consumed energy (example: for backup heater
(if applicable)) 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 (if applicable) 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 (if applicable)
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.
1 power meter. You only need 1 power meter that measures the entire system
(compressor module, hydro module, backup heater and booster heater) in the
following cases:
▪ Normal kWh rate power supply
▪ Preferential kWh rate power supply WITHOUT separate normal kWh rate power
supply
Power meter
1 Measures: Entire system
Connection: X5M/5+6
Power meter type:
▪
▪
2 power meters. You need 2 power meters in case of preferential kWh rate power
supply WITH separate normal kWh rate power supply.
Description
Three-phase power meter in case one of the following
conditions is met:
- Power supply of the external backup heater kit (if any) is
3N~
Single-phase power meter in other cases.
