I often make my own gadgets but it's a lot cheaper than I could make one not to mention the hassle. I use it to control the temperature of the Leach amp heatsinks. All I had to do was extend the thermal sensor to get to the heatsink and now the amp runs with no fan noise. When I'm driving it hard, the volume is loud enough to drown out the fan noise when the controller accelerates to increase cooling. The data in the list is not enough to understand how the device is used, but you can find videos on the Internet to clarify the situation.
