What causes this fault?
This is not actually a fault, but rather a status message indicating that the boiler is currently measuring and displaying the temperature of the water coming back from your radiators. It occurs during normal operation when the control system or an engineer has requested to see the live return temperature data on the screen. Your boiler will continue to provide heating and hot water as normal while this code is visible.
