Green-vent Solar Environment Control System


The ECS is an automated system for running the fan when the environmental conditions demand it, such as excess temperatures or humidity. The ECS runs on the 12V power of the Solar Panel, so if there is no sun the ECS will not operate. Alternatively, you can plug the ECS into mains power using a transformer (included with the 30W GVS). The fan will then run on Solar Power when available, and on mains power if the environmental conditions demand it . When running on mains power the fan will run for 8 mins every half hour which is enough to provide adequate ventilation.

The settings of the ECS as as follows:

  • Temperature Control: Turns fan ON at 27°C & OFF at 25°C.
  • Humidity Control: Turns fan ON at 75%RH & OFF at 65%RH.
