I only have 1 valve/zone, a Rain Bird DAS-075 3/4" and I got the 8 zone Rachio3 so I can automate the usage with my phone. There is a black and red cord coming from the valve that the manual says can be interchanged. I put the black into the common on the Rachio and the red into zone 1, but nothing happens when the Rachio runs a test. Should I put the red cord into the master valve instead? Thanks in advance for any help.
Manual for the DAS-075 is https://www.rainbird.com/sites/default/files/media/documents/2018-02/man_ASVF.pdf
