These will include a WEATHER STATION and FAN CONTROL SYSTEM which will only allow the fan to run when temperatures and humidity are within the range that the grain manager/farmer has preset. More specifically, the fan will not run if humidity is too high or perhaps even too low (to prevent over drying) or when the temperature is too high or too low, both programmable. There will be additional modules that will allow the DELAYED START of multiple fans. A RESETTABLE TIMER that will let you know how many hours your fans did run. Lastly, a MANUAL OVERRIDE.
