Attic Breeze solar attic vents ship standard with a thermal switch included to control the operation of the vent based on the temperature of the attic. The thermal switch minimizes attic heat loss during colder months and extends the run life of the unit. Removal of the thermal switch allows the solar attic fan to be operated continuously, where attic temperature does not control fan operation.
