Technical description
Temperature display in Fahrenheit
What causes this fault?
This happens when the boiler's internal control unit has been adjusted to display temperature units used in the United States rather than the UK standard. It is usually triggered by someone accidentally changing the display settings within the user menu or during a recent service. It does not indicate a mechanical failure or a safety risk to your heating system.
DIY fix possible
Navigate to the main menu on the control panelSelect 'Settings'Change the temperature unit from '°F' back to '°C'
