The Green-Vent Solar Attic Extraction Fan is an attic ventilation system that can be installed into commercial or residential rooves to remove the trapped heat between the ceiling and the roof. The temperature inside your roof/attic space can reach temperatures up to 70°C (170°F) during the summer months which creates a heat load on ceiling insulation and air conditioning duct work. Green-Vent Solar utilizes the renewable energy source, the sun, meaning it costs you nothing to quietly exhaust the hot air and help reduce the cooling costs of your building.
During the winter months any moisture laden air trapped inside your roof/attic space can condense in the cooler temperatures, resulting in the growth of mold and mildew. Circulating clean fresh air will reduce the occurrence of this and prolong the life of your roof.
The amount of ventilation an attic needs is determined by many factors, but in general the more the ventilation your attic has, the better off you will be. As attic air turnover is increased and fresh make-up air is brought into the attic, the attic temperature will begin to approach that of the ambient outside air temperature, which in turn minimizes heat transfer into your home. As long as your attic has plenty of fresh air make-up ventilation, more airflow through the attic will only increase the cooling performance of your attic fan.

The ECS is an automated system for running the fan when the environmental conditions demand it. If the temperature or humidity in the attic space is too high the fan will operate. Once conditions return to lower levels, the fan will stop running. When running on mains power the fan will run for 8 minutes every half hour.
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.
