What measurements does the meter provide?
It measures active energy (import/export), reactive energy, instantaneous power, voltage, current, frequency, and power factor. All values are accessible via KNX group objects.
Can I use the meter for billing purposes?
The meter is MID-compliant (optional) and can be used for sub-billing when correctly installed and sealed. Check local regulations for legal metrology requirements.
How do I read the display?
The backlit LCD cycles through measured values automatically. You can also navigate manually using the button. The display shows total energy, current power, and tariff information.
What is the accuracy class and is it reliable?
The accuracy is Class 1.0 according to IEC 62053-21, meaning a maximum error of ±1% for active energy. It is suitable for monitoring and efficiency analysis.
Does the meter require external power?
No, it is powered via the KNX bus (29 V DC). No additional power supply is needed. Ensure the bus voltage is within specifications (21-30 V DC).
How do I reset the energy counters?
Energy counters can be reset via KNX (write to appropriate group object) or through the ETS configuration. The device also supports partial counters for billing periods.
What should I do if the display is blank?
Check the KNX bus connection and voltage. Ensure the bus power supply is functioning. If the issue persists, try a bus reset by disconnecting the bus voltage for 10 seconds.
