Hello, so sorry for the lateness, had a few things on and it slipped my mind.
Here is how I have my 4CHPROR3 configured
For starters, Ignore R4. I have some lights in the garden which is what is wired up.
So power wise, I spur off the actual garage controller into the 4CHPROR3.
I have 4 wires (ignore yellow, not used)
- Black Goes into R1 COM, then i use the purple wire to link to R2 and R3 COM
- Brown R1 NO
- Red R2 NO
- Orange R3 NO
At the other end
- Black goes into Common
- Brown goes to UP
- Red goes to Stop
- Orange goes to Down
I have also wired in the original Ribbon cable as well as a backup.
Hope that helps
