I'm not sure about your thermostat, but I had one that had a detent you had to pass before it was really off. Some of these OEM 'stats have the on/off/auto so close together that I've had to put the selector all the way to one side and count the detents as I move the lever to be sure off is off.
Most thermostats with those slide switches usually have two of them. One selects the mode (off/heat/cool), the other switch (on/off/auto) is for the fan.
