Couple of quick questions - Switching from a Rainbird to the newest Rachio. My experience with these hookups goes no further than switching to a Nest thermostat, so please forgive my stupidity in some of these questions:
(1) The 24VAC and GND from the Rainbird do not need to be connected, correct? Any need to cap these wires for protection if just leaving them unused?
(2) I have a small looped yellow wire connecting two terminals under SENS on the Rainbird. Which S terminals should I connect to on the Rachio?
(3) I also have two separate common wires on the Rainbird going to the COM terminal. Ok to connect these to any C terminal on the Rachio or do they need to connect to the same one?
