I bought a Rachio 3 - 8 zone system to replace my Hunter SRC 900i, but have not connected it yet. I have following questions:
It seems my current system has something called SRR(image attached) and it is wired in the system, does Rachio have connection ports for this or should I just leave those wires not connected?
Also attached is my current wiring diagram. I am confused which one would be my common wire because as per hunter’s documentation (also attached) RS port has Common and the weather sensor wire attached together. From general wiring practice is white wire would most likely be a common wire?
Also because Rachio supports hyperweather, can I skip connecting the weather sensor (do not know what current model is)?
Regardless, If I decide to connect the weather station to the Rachio system, how do I wire them, meaning on which port the current brown wire connected on RS would connect on Rachio? and where do I connect the black wire connected to C currently?
No SRR exists for Rachio and is not really needed as you would use the app on your smartphone.
Wiring: see below
At least to begin with, I would not connect the weather sensor to see how well the weather works for you. You can always add it later.
If you add the weather sensor in the future, I believe it depends on the sensor itself. In any case and as long as it is two wires, one wire goes to S1 -or- S2 and the other to common, 24VAC, OR -24VAC.
AC--------Black & Red----use supplied Rachio power and app (not SRR)
Black believe power, red seems to be for SRR
AC--------Black & White–use supplied Rachio power and app (not SRR)
Black believe power, use supplied Rachio power; white seems to be for SRR
