Simply plug it into a power receptacle and then plug your cooling device into its outlet, then choose your preferred room temperature setpoint with the rotary knob. When its built in sensor senses that the room temperature has exceeded the setpoint by at least 1F, it will automatically activate your cooling device by powering the outlet.
