Installation
You should definitely read the manual and watch the videos on the Tailwind site before you start installing the iQ3. While it’s not difficult, it’s not intuitive and the instructions are essential to doing it right. The entire process took about 35 minutes.
You start by putting the two-part sensor on the garage door. The switch clips to the track, while the magnet goes on the door itself. It’s important to align the two parts properly so the module knows when the door is opening or closing.
Next, you run a wire from the sensor to the module, which should be located on the side of the garage door opener. Using the included clips helped keep the wire tight along the track and kept the wire out of the way. The wire then connects to the module. If you have a garage door opener with a “learn” button (as I do), you’ll need to connect an adapter to the module. Press the learn button on the opener and hold down the appropriate door button on the adapter to teach it the code.
