Customer's Fault Description
Same problem you repaired in late 2017. Low battery displayed on screen, despite new batteries.
This Velux control arrived safely and on adding batteries was confirmed to have a low battery display and a cycling display.
On opening the issue was found to be corrosion over the battery terminal, this was re-coated using conductive paint which restored normal functionality.
