In place of using the pulse count, the flow can also be measured with a flow sensor
(10 V or Hz) connected to one of the Hx inputs.
The parameter Flow measurement yield determines which input Hx is used to
meter flow:
None
No metering at input Hx.
With input Hx
The flow via the selected input is acquired and used for calculating the volume. The
determined volume is multiplied by the measured temperature difference and
added to line 8526 "Daily yield solar energy".
The Hx input selected here must be set in the configuration for the flow
measurement.
