Double doors
For double doors, the MASTER door must be learned first and thereafter the SLAVE door. When the
SLAVE door is learned, the MASTER door will open up to fully open position during the learning
phase of the SLAVE door.
The doors can also be learned separately before connecting the sync cable. In case of astragal doors
and separate learning, the MASTER door must be held open before the SLAVE door learn is carried
out.
