I am planning a 300cm long reef aquarium against an outside wall. A company specializing in ventilation can sell me three extractor ventilation fans that will go in the wall over the tank. They have fans that can be controlled via a 1-10v connection.

So I want to use my Profilux 4 with a humidity/temp sensor to control the speed of these ventilation fans depending on the humidity above the tank.

Is this possible? If so, how would I connect the ventilation fans' 1-10v connection to the 1-10v inputs on the Profilux?

Thanks!
