Flex-a-Lite Variable Speed Controller with Temperature Sensor
The Flex-a-lite Variable Speed Controller turns the electric fan on and off at the desired temperature. Fans turn on at 60-percent power and fan speed increases as the temperature rises. You can easily adjust the activation temperature between approximately 160-240 degrees Fahrenheit. It also turns the electric fan on when the vehicle air conditioner is engaged. Fan will run for up to 45 seconds after the vehicle is turned off.
