Sounds like you have something wired wrong.

I suspect you have checked the obvious, the fan switch on the thermostat in the "auto" position and not in the "on" position. Triple check your fan wires to be absolutely certain they are hooked up per the wiring diagram before you go any further. If your fan connections are in exactly the same position as the old fan was, the fan should not run if the fan switch is in the "auto" position. If it is running continuously with the wires connected correctly, your fan relay must be stuck in the energized position. This could be because of a bad relay or it might be a shorted low voltage control wire to the thermostat. If the relay is not part of an integrated circuit control board, shut off the power and remove the red wire from the fan relay and re-energize the unit and see if the fan still runs, if it does, the relay is stuck. If the fan does not run, it means the low voltage wiring is shorted somewhere and is energizing the relay even in the "auto" fan position. If your unit is controlled by an IC board, you will need a new IC board.
