    Honeywell TH8000 intermittent
    I have a few months old Lennox heat pump with Honeywell TH8000 thermostat. Most of the time the thermostat works great but once every two weeks or so the inside temperature on the unit says 75, the thermostat is set to turn on heat at 72, and the heat comes on! The programming is set for manual, the fan is on "auto", the system is set to "heat". The dealer has looked at it several times and said that "he's set everything to manual that he knows of" -and it still does this. For A/C last summer we had it programmed and it worked the program flawlessly.
