Display And Fault Codes - Riello START AQUA 24 BI Installer And User Manual

The bacteria is eliminated by bringing the stored water to a tempera-
ture exceeding 50°C/55°C.
It is therefore recommended that the DHW temperature selection
knob be set to the maximum value at least every 2/3 days to bring
the water temperature to 63°C, maintaining this temperature for at
least 5 minutes.
