Follow this replacement guide to replace your control board. You will need a 3mm Allen Key and a size 1 Phillips screwdriver before starting on this venture. There are more than a few steps but this guide also overlays other guides. Such as “opening the device”, “Replacing the Display” and “Changing the Battery of the Control Board”. I would set aside time and patience for this task. You can also check out the device’s troubleshooting page VENTImotion and VENTIlogic Ventilator Troubleshooting
For more information on replacing the control board, please refer to page 39 in the service manual.
