▪ You can read out the energy data:
- Per two hours (for the last 48 hours)
- Per day (for the last 14 days)
- Per month (for the last 24 months)
- Total since installation
INFORMATION
The calculated produced heat and consumed energy are an estimation, the accuracy
cannot be guaranteed.
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
- 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.
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.
