The ECOFIT fan regulator is especially designed to be used with ECOFIT motorized backward wheels on «G9» and «V8» motors (motors with electronic commutation). It is made of a specific box with a pressure sensor and a microcontroller. The drive cable of the motor is connected to the regulator. The regulator has also a drive cable for the user. It is then possible to control the pressure and the airflow according to the selected mode.
