How to use
Plug in your fans, set the temperature and humidity you want for the day and for the night, then set the minimum and maximum fan speeds. The controller adjusts the fans to hold those conditions.
Balance the extraction against the intake so the room stays under negative pressure. For EC fans you need the right G.A.S cable pack, sold separately. See the other fan speed controllers.
