Flex-a-lite 31163 Variable Speed Control Module with Threaded Temperature Sensor
Product Description
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 160-240 fahrenheit. When
fans come on with temperature, they are activated at 60 per cent
run using a soft start feature, which greatly reduces startup
amperage. As the temperature rises about 10 degrees, the controller
gradually increases fan speeds up to 100 per cent.
