    Your thermostat doesn't have a "fan" switch on it? Maybe if you put another thermostat on your system that does will make it easy without causing other problems.

    Thermostat doesn't have a Fan ON side? Otherwise use a single pole, double throw switch. Hot to the middle terminal, Switched one way the heater circuit is energized, thrown the other, only the fan. You will need a hot jumper to the fan only side.

    If your thermostat doesn't have a switch marked ON/AUTO it should be replaced with one that does for about $25
