    Rheem Mod Stat: common problem?

    When my Mod was installed, the contractor programmed it, showing me how the 'copy' feature worked.

    On a few occasions, I tweaked the program, but I could not get the copy feature to work (in 7 day mode). I did discover that it would work in 5/2 mode (a minor inconvenience).

    Some months later, after complaining about a room temperature droop, the contractor and a Rheem specialist, came out and checked out my furnace and stat. They wound up replacing a 411 with a 411.

    I could not get the stat to copy (7 day) so I just programmed each day individually, thinking that I was doing it improperly.

    After re-reading the manual several times, and still being unable to copy properly, I just changed to 5/2 day mode and everything works just fine.

    Since my droop (main problem) was corrected, I decided to leave well enough alone and just use the stat as is.

    It seems unusual that the first stat would lose the 7 day copy feature, but retain the 5 day copy, and the second one would not be able to do it at all.

    Just wondered how many of you PROs have (or haven't) come across this problem.

    Seems to me, I did mine on 7 day, but then again, it's been a while

    I have no issue using copy on 7 day setup.
