The Flex-a-lite Variable Speed Control Module is an adjustable fan controller that can be set to have your fans come on at any temperature between 160-240F. When fans come on with temperature, they are activated at 60% run using a soft start feature, which greatly reduces startup amperage. As the temp rises about 10 degrees, the controller gradually increases fan speeds up to 100%.
