Technical description
Return temperature actual value
What causes this fault?
This is not a fault, but rather a status message triggered when the boiler is actively monitoring the temperature of the water coming back from your radiators. It occurs during normal operation to help the boiler's internal computer calculate how much heat is needed to keep your home comfortable. You do not need to take any action as your heating and hot water will continue to work as normal.
DIY fix possible
No action required as this is an informative status code, not an error.Press the 'i' or 'back' button to clear the status from the display.Monitor the boiler to ensure it continues to provide heating and hot water as normal.
