No zones working - Rain sensor?
Went to fire up the system for the first time in a new house, and nothing. Here's what I know:
1. I can manually activate 4 out of 5 zones (the 5th zone I am unable to find the valve).
2. I have correct voltage at the controller. I do not seem to be getting any voltage at the solenoids.
3. I found the wire coming from the rain sensor was cut (I'm guessing unintentionally). I connected it back up and still nothing.
What's odd is I have no idea where the rain sensor is wired to. The controller does not appear to support a rain sensor, and the wire coming from the sensor definitely doesn't terminate at the controller. The only thing I can possibly think of is somehow the sensor is wired to the valve box that I am unable to find, but this doesn't seem likely because there's a valve box about 5 feet from the sensor, and the wire is not in there either.
It seems like the issue may be with the rain sensor, but that's just my uneducated guess. Any suggestions on how to find this missing valve box, and how to figure out how this sensor is wired?
