Hey Community!

Just moved to a new house, and would like to change a 1990’s Rainbird to a Rachio3. I was hoping the community could help with which wires I need to attach to the new unit (and which ones to just ignore)

Please see the picture enclosed of my current setup. Obv 1-10 zones are easy.

What are the left 3 attachments and where are they used? (ORN, ORN, GND)

On the bottom, what and where should I plug in COM?

Thanks so much in advance

I actually think I solved everything myself.

Thanks to the community!
