Wiring issue swapping out old controller Richdel 446pri

I recently moved into a new house that had an older sprinkler controller. I tested the system to confirm it worked before switching in my rachio gen 1. When I wired up my rachio gen1 no zones turn on. I swapped the unit back and everything worked with the old controller. There is an extra red and white wire attached to the old controller that I’m not sure what it’s used for so it was not connected to the rachio. Any ideas? I attached a picture of the original wiring.
