I just got this set up and all looked well. Nice design....except it won't stay in contact with the outsidebase that is only 20 feet away on the front porch (covered and protected) only one wall to penetrate.Have to reset the clock 2 and 3 times a week. It's a shame, this is a nice designed unti with a backlite.UPDATE...........called Honeywell.....they say when it looses contact.PUSH THE DOWN BUTTON to reestablish contact with the base..it works, the outside temp came back on........but for how long it let you know in a new update in a week.
