Hello, new here. Just bought the 202U v6 after failing to find a remote that will work with my old garage door opener. I have an unbranded roll up door with an external control box. I believe this will work, just need some help figuring out how to wire it up. The control box has three switches. Up, down, stop.
I do have an external 12v that I will power the 202U with.
So with this set up can I just run a wire from
N/C to down
N/O to up
COM to COM
Thanks for the help
