8. Fault

8.1 Check meter

Check the temperature and flow measurement values for plausibility after installation and then
at regular intervals.
• Is a flow volume displayed?
• Is a plausible temperature difference displayed (flow and return temperatures)?
• Is a plausible power displayed?
If not, check whether a fault code exists (see "7.4 Diagnostic display" at page 55), or carry out the following
checks/troubleshooting.

8.2 Troubleshooting

Before checking the meter itself for defects, check the following points:
• Is the heating/cooling operating?
• Is the circulation pump running?
• Are the shut-off valves completely open?
• Is the pipe clear (clean any strainers)?
• Are all the temperature sensors and meter seals intact (tampering)?
• Is the meter rating correct?
• Is the direction arrow on the flow sensor in the flow direction of the heating medium?
• Are the flow and return sensors fitted in the correct line?
• Is the meter fitted in the correct line (flow or return)?
• Is the energy unit (e.g. MWh) printed on the meter correctly selected?
If you have checked the specified points and the meter is still malfunctioning, then please email us
(including serial number, meter type, article number) with a detailed fault description and, where
necessary, a photo.
