Navien Combi boiler icon help

Options

Does anyone know what this display icon in the upper right hand corner means? I have looked in my manual and all over the internet but, still can’t figure it out

Thanks in advance!

    THANK YOU!

    I have literally been in that manual for hours and missed that icon.

    Thanks again!
