The dial on the temperature regulator will allow you to adjust the heat output from low to high as needed. Number 1 is the lowest setting (20% of total output) and number 7 is the highest setting (100% of total output). Just plug the 3-pronged end of the regulator cord into the wall and plug your Chick Brooder Heating Plate into the other end.
Specifications: 110 volt cord is 29" long and the temperature regulator is 6"x3"x1"
Safety Note: This product is only for use with the Chick Brooder Heating Plates. It is not for use with equipment that draws more than 110 watts and it
