Open/Close/Stop Operation

(Only if you have a Multifunction door control)
Your Security✚® remote control can be programmed to operate one door using all 3 buttons: the left button will only open the door, the middle button will only close the door, and the third button will stop the door’s movement. You may set up this feature as follows:

  2. Press and hold the Lock button on the door control.
  3. Press and hold the door control push bar.

When the opener lights flash, release all buttons. Test by pressing the left (Open) button on the remote. The door should open. Press it again while the door is open and nothing should happen. Press the middle (Close) button and the door should close. Press the third (Stop) button while the door is moving and it should stop immediately
