Water will not turn on
I have power to my box. I have programmed the system numerous times. I changed the backup battery. If I open the valves manually, the water comes on and the nozzles spray great. The are no broken pipes. The auto and the semi auto options will work though. I have an Irrtirol-600 box. When I try the semi auto to start the cycle, the box blinks, it says it is starting, but no sprinklers come on.
