Designed to control solar powered pumps in closed loop solar heating systems, this differential temperature controller will improve performance by preventing a solar powered pump from running if the collectors become cooler than the storage tank. This typically occurs on overcast days and early and late on cold days when there is enough sunlight on the solar panel to power the pump, but the collectors are not hotter than the storage tank.
