To check instantaneous or cumulative water/gas flow:

1. While the unit is running, press and hold the query button (often indicated by a square icon) for 3 seconds.
2. Within 5 seconds, the display will show the instantaneous water flow (L/min).
3. Press the query button again to view the instantaneous gas flow (m³/h).
4. To view cumulative flow, stop the unit from running, then press and hold the query button for 3 seconds.
5. Within 5 seconds, the display will show the cumulative water flow.
6. Press the query button again to view the cumulative gas flow.

6. Maintenance
