The power is supplied by a transformer, and when the thermostat makes contact between the 24 volt power and one or two of the other wires, a relay back at the heating/cooling unit activates the corresponding heat/fan/cool function of the unit(s).
This points to a bad thermostat. Try this: take the batteries out of the thermostat and turn the power to the furnace off for 30 minutes. Now replace batteries with fresh alkaline batteries and turn furnace power back on. Try again.
