My sprinkler system was just installed and the installer put the Irritrol rain sensor wiring like this.
I found the support article from Rachio saying it should be wired like this:
Should I remove the white wire from S2 and put it in the 24V slot?
@mbaturin - yes.
Move the white wire from S2 and put it in the 24 VAC - slot. Then confirm that Sensor 1 is set for a rain sensor and nothing is set for Sensor 2.
