Parameter "Pulse count yield" is used to select input Hx for metering the amount of
heat or the flow of water:
None
No metering via input Hx. This setting is important if the inputs are used for other
pulse counts (e.g. acquisition of energy input).
With input Hx
The pulse counter is read by the selected input and the energy determined from it
is added to the reading of the meter used for metering the heat delivered.
It is important that the Hx input selected here is also selected in the configuration
for the pulse count.

The pulse measurement occurs via the input Hx selected via line 3886.
The sum of the counted pulses is displayed in the pulse counter (line 7842).
None
The pulse value is not counted.
kWh
The pulse value is interpreted as kWh and added to operating line 8526 "24-hour
yield solar energy".
Liter
The pulse value is counted as liters. The yield in kWh is determined based on the
volumetric flow and temperature differential between collector flow and return and
then added to operating line 8526 "24-hour yield solar energy".
The calculation model is compared to the applied pulse counter using the settings
counter and denominator.
