3100 Pulse count energy
The parameter Pulse count energy determines which input H1 or H3 is used to counter
electrical energy or natural gas 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 supplied energy).
With input H1, with input H3:
The pulse count is read from the set input and the established energy (electrical or
natural gas) is added to the counter for employed energy.
It is important that the count input set here is also set in the configuration for the pulse
count.

Pulse value energy numer

Pulse value energy denom

The value of a pulse is entered with three setting parameters as a quotient (nominator
and denominator) and the physical unit:
Pusle valency = (numerator / denominator) * unit
Example 1: Pulse unit energy numer = 1
Pulse value energy denom = 100
Pulse unit energy = m3
Pulse valency = 0.01 m3/pulse (or 100 pulse/m3)
Example 2: Pulse unit energy numer = 1
Pulse value energy denom = 100
Pulse unit energy = kWh
Pulse valency = 100 pulse/kWh (or 0.01 kWh/pulse)
The selection of the pulse unit distinguishes recording of used energy for electrical or
natural gas operated heat pumps:
Pulse unit energy = kWh
The pulse or its energy value is added directly in the counter for employed energy.
