1 = supply temperature probe is not connected, pipe is interrupted or broken
2 = return temperature probe is not connected, pipe is interrupted or broken
3 = negative temperature difference; temperature probes were exchanged (except in
case of combined heating/cooling metering)
4 = Analog to digital converter is broken (instrument must be replaced)
b = low battery voltage (replace battery)*
A1 = trouble with flow measurement
1 = backflow in meter or in pipe system
2 = air in the pipe system, broken ultrasound probes or very strong deposits on the
probes (cleaning or inspection required)
3 = exceeding the maximum admissible flow
* this message is a warning and does not cause measurement shut down.
4 = connection cable with flow transponder or connection to the ultrasound probes
has been disconnected.
5 = no flow for > 24 hours, but ΔT > 15 K
6 = no data communication between integrator and flow meter
7 = problem with the option board
