Hank Hill, the zero'd out feature must be new. mine doesn't do that when it loses signal, it just continues to show the last read temps. i wish mine did zero out. the only way to tell sometimes is if the temps don't change for awhile, i go out side and look at the outdoor part. usuually it will fix itself and start reading again, but every once in a great while i have to turn everything off and back on.
