What causes this fault?
This fault occurs when there is a software mismatch or a data corruption issue between the boiler's internal computer and the display unit. It typically happens because the two components are unable to 'talk' to each other correctly due to a failing circuit board or a loose communication cable. Effectively, the boiler recognizes that the software version installed isn't compatible with the hardware it is trying to control.
DIY fix possible
Turn the boiler power off at the fused spur switch for 30 secondsTurn the power back on and wait for the system to rebootCheck if the display returns to the standard temperature screen
