Siemens RVS41.813 - Counter;Performance Factor; Electric Source Output; Heat Delivered; Mean Gas Energy Content

Pulse unit energy = m3
The pulse or its volume value calculates, via the average natural gas content, the
natural gas energy which is then added to the counter for employed energy.

Line no. Operating line
3106 Mean gas energy content
The employed natural gas energy is calculated using the counted volume and the
adjustable average natural gas content if the pulse count for volume is parameterized
(
pulse unit energy = m3):
Natural gas energy [kWh] = Volume [m3] * average natural gas energy content
[kWh/m3]
The value of the natural gas energy is then added to the counter for employed energy.
Line no. Operating line
3108 Electric source output
Electric sourc
e output
This function calculates, using an adjustable electrical source performance, the runtime
and rpms theoretically electrical energy used to operate the source (pump/fan).
Source operation [kWh] = runtime [Min] / 60 * rpms [%] *
Electrical source performance
[kW]
Runtime is recorded at an accuracy of 1 minute. The state of source pump Q8 or the air
fan K19 is recorded.
The determined energy for source operation is added to the counter for employed
energy (electrical or natural gas).
The function must be sw
itched off via both parameters ("---") if metering of source
energy via the performance parameter is not desired.
Counter/performance factor
The following parameters are display values for the counted or calculated values
Line no. Operating line
3110 Heat delivered
Heat delivered
Heat supply as determined using the pulse counter and the calculated delivered heat
are added every minute to the counter
Delivered heat.
Delivered heat =
dT * volume (calculated) + dT * volume (counted) + heat (counted)
Internal to the controller, delivered heat for heating and DHW are recorded separately,
but only the total value is displayed. They are, however, listed separately in the fixed
day storage (Par. 3120-3188)
