very good solution for fan cooling in our root cellar. We set it up opposite of the directions for solar hot water systems. It also helps to maintain the proper humidity for vegetable storage, not too high or low. We used a power relay to protect the controller, as suggested, and set the differential at only 3ºF. For humidity control, this setting works best in New Mexico. In wetter conditions, use higher differentials. Last issue, use a larger radial fan than the normal household vent system - - you need to move more air than you may think to get good results.
