: The availability of these measurements requires that the data register 00302 VolumeFlow is available and that a differential temperature
measurement is established by one of the below means:
MGE model H and later:
• Direct measurement, where an analog or temperature input has been configured to Remote differential temperature RemoteDiffTemp
(register 00346).
• PumpLiquidTemp (register 00322) measured by build-in Grundfos sensor and RemoteTemp2 (register 00337) measured by analog or
temperature input.
• RemoteTemp1 (register 00320) and RemoteTemp2 (register 00337) measured by analog or temperature input.
MAGNA3:
For the calculation, an estimated flow value and measurement of the liquid temperature by the build-in temperature sensor is used.
Connection of an external temperature sensor is needed for the pump to calculate the needed differential temperature.
A data value of 0xFFFF indicates "not available".
Estimated flow can be used for monitoring purposes only. We do not recommend it for controlling purposes.
