    Honeywell TH8000 Series Thermostats
    I have 11 Honeywell TH8000 series stats. All purchased and installed at the same time, 1 year ago. Only one of them offers the "auto" option under "SYSTEM" How can I get the rest to offer me this option. I searched the Owner's Guide but can find nothing other than description.
