The following can be selected as measured
values:
-
Heat power
-
Flowrate
-
Flow temperature
-
Return temperature
-
Temperature difference
The following can be selected for the output
signal:
-
0..20 mA
-
4..20 mA
-
0..10 V
A minimum value can be defined for each channel, below which the output does not fall,
irrespective of the measured value. This enables detection of a wire break, for example.
Parameter setting (selection of the measured value, output measuring range, and minimum
value) is performed via the heat meter using the PappaWin software.
The output signal is updated in a 4-second timebase. An LED (ERR) indicates the current
mode.

(analog module)
Power supply
The power supply of the module is drawn from an external connector power supply unit (not
included in the scope of supply). If the heat meter is operated with a battery, a 6-year battery of
type D (“for all applications”) is required.
Note: CE compatibility (“CE mark”) is only ensured in conjunction with the intended power
supply unit.
Use only the
specified power supply unit
! Use of an unsuitable power supply unit can
result in malfunctions or destruction of the heat meter or module.
Analog output
For the current output, a maximum burden (load) of 100 ohm is permissible.
The voltage output is not short-circuit-proof.
The
pulse module
permits the output of pulses (“
tariff
pulses
”) that can be derived from the quantity of heat, the
volume, tariff register 1, tariff register 2, or the mode. Two
channels are available whose functions can be
parameterized with the PappaWin software.
Output takes the form of
standard pulses
or “
fast pulses
”.
The pulse duration is identical for channel 1 and channel 2.

Note: If two pulse modules are plugged, please note the restrictions!
