We put in an attic fan because of poor roof ventilation with the ridge vent. This combined with not enough attic insulation caused us to have a moisture problem in the attic. The fan we had installed has both a temperature switch and a humidifier switch, so if it gets too hot or too moist it turns on. Combined with the addition of blown in insulation, we noticed a huge improvement in both heating and AC costs, and didn't have the horrible moisture problem. Don't remember the name of the fan unit, but it was hard wired to electric and was only about 8" diameter.
