ting the preset pot until the LED is flashing red/green. After calibration is complete, remove the diode from the chilled water. The LED should stop flashing and turn steady red, and then to green. Repeat this process to validate the system is operational. The system is now ready for installation.The first thing to decide, in the installation process, is where to place the three main components of the system. The sensor diode should be placed as low to the ground as possible. Two areas are recommended. Behind the front license plate or in a protected area within a forward wheel well. Next are the LED and the Box. If both are going on the dashboard the LED may be mounted on the Box itself. If a separate mounting is preferred, then the Box can be mounted under the dash and the LED can be mounted in another small box, or in an unused vehicle switch location. Once the location is determined for all the components. Measurements are taken to determine length for the wires that connect the system. Care must be taken to insure the wire path is protected from fraying, corrosive conditions and moving vehicle parts. Now that the Frost Box is installed and operational, the operator will be able to determine black ice conditions. The primary application for the Frost Box is installation on motor vehicles. Another application for the Frost Box is installation in green houses, to determine when heating should be turned on. I found this system interesting to report on. Not only because of its simple design, but because my husband constantly warns me to be careful during the inclement winter weather here in Ohio. I hope you found it interesting too....
