Heater ventilation control box

I designed this control box to make the ventilation system I previously proposed very simple.This is used to start the fans automatically once the radiator reaches the temperature you have set.In addition, the speed regulator also has an on/off function.The construction requires a minimum knowledge of electrical connections.In the print file, two bases of the box are introduced.This is because the supplies of the speed regulation cards can vary.I point out the links where you can get the components used.
