This guy's boiler was faulting out, now this morning he says it's working again, anyone seen a wb2b stop working and display Without Function? Normally there's a code! Anyway, we will call Viessmann if need be.

    Was he playing around with the settings? He have kids that would have touched it? Gremlins?

    from the manual:

    ”Without function” is displayed

    Cause: No function is allocated to the key you have
    pressed.

    Remedy: No action required. Select appropriate key."

    don't think the kids got to it, yet there was a fault (he sent me a pic) and he could not get the fault code to show on the display. The system started working and we postponed going there today (too busy anyway)
