• On the top-left are REM (remote), AC2, AC2, and GND (ground). Instead, you will use the app (as remote) and the Rachio power adapter.
• On the bottom-left, you have SEN, SEN, and COM. I personally would suggest connecting without the sensor to begin with (maybe even never connect). COM (common) would be used, but I would have to remind myself how the sensor is wired in to know which way to wire so it works correctly without the sensor which would connect differently anyway.
• On the right, it looks like you have a P/MV (pump or master valve) and zones 1-7 which would go directly to Rachio

I know, more than you asked.

Thank you for the prompt response. Seems simple enough!

I would suggest making sure all the zones are working before the transition, If it has wires that are not hooked up, I would label wires (maybe anyway).
