Upgrade Unknown Rainbird Controller to Gen 2


Good Afternoon -
I am really interested in upgading my existing Rainbird controller (unknown model). I have been unable to identify the model, but was able to open it up, and it seems fairly straightforward. From the documentation online it seems that the wires on the right go into the zones, white on the lower left is common, but the mystery to me are the three in the upper left (red, yellow, blue)…
any help would be greatly appreciated.
Thanks, and have a great one.


Looks similar to PC-106: http://www.rainbird.com/documents/diy/man_pc100series.pdf

These are power input terminals, can be disregarded / disconnected. Rachio comes with its own supply.



Hi Gene -
That is it! I can’t believe I missed this. Thank you so much for the quick reply! I think I’m going to go for it!

Thanks again and have a great one!


No worries, the battery threw me for a loop, wanted to make sure it was for memory backup rather then running a DC controller. Switch over should be pretty straightforward process. Welcome to the club :wink:
