First use: type the 5-digit serial number of this trailer. It becomes the panel's Bluetooth name, "Schubi" + the number. The panel restarts under that name, and you pick it once more.
You are driving this trailer. To drive another one, tap Switch trailer and pick it from the list (Schubi + its serial number).
Change this trailer's serial number
Settings change how the panel works. A wrong change can stop the trailer from working. Only continue if you know what you are doing.
Overrides
Dach, RW, Schl W and Spriegel: on while you hold them. The others: tap to switch on, tap again to switch off. Several can be on at once.
Support
Safari can't use Bluetooth. This iPhone needs the free app Bluefy to drive the panel.
