Hello! Thanks in advance to anyone who takes the time to assist with my questions. Apologies in advance if they’re rather rudimentary. Just bought my first home recently and excited about installing the Rachio system but don’t want to mess anything up. I’ve attached some pictures below but please let me know if anything else is needed.
First picture is the outside of my current unit (Rain Bird ESP 6-LX Pus) and second picture is of the zones wring. I think I’m set on moving the majority of wires, looks like the COM, 1-5 on my current unit would move to the C, 1-5 on the Rachio.
The spot I’m getting hung up on is the Sensor wiring (third picture attached below) for multiple reasons. First is that I only have one sensor (which should be the white wire running to the top Sensor ports). So does anyone know what the purple wire would be for? Also what is the purpose of the red wire running between both Sensor ports? Lastly, how would those Sensor wires transfer over to the Rachio?
