System operation switches off — Water temperature protection or overload

What does System operation switches off mean?

The system may switch off if the water inlet temperature drops below 10°C, engaging the backup heater, or due to other protection controls.

• Incoming water temperature is too low (< 10°C).
• System protection activated.
• Potential issue with the water inlet sensor.
