accessories).

ACTIVATION button or wall control:
• If open, the door will close. If closed, the door will open.
• If closing, the door will stop.

and exit of pets and for fresh air).

closed position, it will reverse direction.

door to open and prevents an open door from closing. It
is STRONGLY RECOMMENDED for homeowners with
