Calculation and update of the energy counter occurs periodically every minute. The
following occurs when the functions are switched on:
•
The pulse counter is read and the energy or volume value are calculated.
•
Calculates electrical energy to operate the source.
•
Measures temperature difference.
•
Calculates volume flow.
•
Calculates electrical energy, natural gas energy and heat volume.
•
Energy counter plus the increase (per operating state heating, cooling, defrost,
DHW generation).

3090 Pulse count heat
The parameter Pulse count heat determines which input H1 or H3 are used to counter
heat volume or water volume flow:
None:
No metering from input H1 or H3. This setting is important if the inputs are used for
other pulse counts (e.g. recording employed energy).
With input H1, with input H3:
The pulse count is read from the set input and the established energy is added to the
counter for supplied heat.
It is important that the count input set here is also set in the configuration for the pulse
count.

Pulse unit heat numer

Pulse unit heat denom

The value of a pulse is entered with three setting parameters as a quotient (nominator
and denominator) and the physical unit:
The selection of the pulse unit distinguishes recording of supplied energy for heat
metering or volume flow count:
Pulse unit heat = kWh
The pulse or its energy value is added directly in the counter for supplied heat.
Pulse unit heat = Liter
The pulse or its volume value is calculated via the measured temperature difference
between the flow and return of the heating energy and then added to the counter for
supplied heat.
Pusle valency = (numerator / denominator) * unit
