Data scope
- Update on each read-out
Property number; unit number; firmware version; fault messages; missing time; operating time;
quantity of heat; tariff register; volume; mounting location; adjustment values; unit configuration
data; measuring range; M-bus addresses; system date and time; previous year’s values with set
day for quantity of heat, tariff and volume; maximum for power; fault duration and 18 monthly
values for quantity of heat, tariff register, volume, missing time, maximum for power, flowrate
maximum, measuring period with maxima for power, flowrate and temperatures; actual values
for power, flowrate and temperatures.
With its integrated antenna, the
radio module
permits
wireless read-out from a distance of up to 100 meters.
For special mounting situations, the radio module can be
supplied as a version with an external antenna.
The module is programmed via radio telegrams. With a
button, the transmit parameters can be reset to default
values.
Two LEDs indicate the current mode.
Radio module;
with internal or
external antenna
Pulse inputs:
Channel 1,
Channel 2
The power supply of the module is drawn from the heat meter. If the heat meter is operated
with a battery, a 6-year battery of type D (“for all applications”) is required.
The module contains an additional two pulse counters to acquire external counting pulses.
The following must be noted concerning the inputs for the pulse counters:
- Only connect isolated contacts (Reed contact, no open collector)
- No galvanic isolation of the electronics of the heat meter
- External power source or grounding not permissible

Technical data pulse counters
Pulse counters:
2 inputs for external pulses
Counter range:
0..99,999,999
Pulse significance: 0.001...999.99
Counter identifier: 8-digit
Min. pulse length: 50 ms
Max. pulse rate:
5 pulse/s when using both
channels
Max. pulse rate:
10 pulse/s when using only one channel
The radio module reads the data either when data is requested or only once per day.
The heat meter must be in normal mode.
The data are packed and output in various telegram types.
Data content
All telegrams are preceded by the time stamp (date and time) and the property number.
