I have a sprinkler system using an 8 Zone ESP controller and rain sensor installed. Works fine as best I can tell. The other nite I got awakened by a tapping sound, sounded like my zone valves were being operated. I found my Esp controller in its normal position (on-but program was not running). Outsize, one of my zones was up an running, and i heard some valve chatter.
We had a lot of rain in this time period. I figured that my rain sensor was doing it, maybe that water had seeped back into the control box..but I saw no signs of water in the ESp controller. I removed rain sensor and wiring.
I also noted that the valve box that houses the valve for the zone that I found running was full of water from recent rain. I have silicone wire nuts on the wiring connections, however these are not taped up and 100% waterproof.
If my ESP controller was in its normal (on) position, but the timer was not set to be turned on...is there current going outside to the solenoids that open the valves?..that would allow a short circuit to occur if the connections were wet? This is weird. My box is wired up per the wiring diagram from Rain Bird.
or did something really go wrong with the rain senson (i had a drip loop in this wiring and it was installed per the instructions).
any help is appreciated.
