Blauberg ISOB-125EC boxventilator 357m3/h - geluidgedempt - Ø125mm - EC-motor

  • I used de dimmer on the Blauberg ISOB-125EC boxventilator 357m3/h - geluidgedempt - Ø125mm - EC-motor. It does work but the slider up-side down. So dimming down fan blows harder and slide the dimmer up makes it go slower. Can one adjust this in the app?



  • according to the fans datasheet it should ramp up when increasing voltage / slider goes up
    is it correctly wired ? jumper removed ?

    a have a similiar fan running with that blue gen 3 dimmer and it works as expected. inverting via software isnt possible with stock firmware / without scripts
