First determine if the RainDial controller “thinks” it’s turning on the valve by watching the LCD screen a valve is on. If a small number matching the valve number appears on the top row of the screen, the controller “thinks” it has turned on that valve.
- If you do not see the number and the LCD blinks and says off, the controller has most likely failed and there really isn’t much you can do. Simply send it to us for repair, we’ll get it back to you.
- If you do see the number, the controller has done what it can to turn on the valve and the problem is likely due to one of the other issues described below.
When the Irritrol controller “thinks” it turned on a valve but the valve doesn’t work, there are several possible reasons.
- The battery is good (so the display and timer appears to function), but the valves do not activate but he power is off so the valves cannot activate. Check breakers, power wiring… and the fuse.
- Battery is good, but transformer has failed – see links on testing the transformer. There are very simple ways to check the transformer Click here.
- Wires have broken, are disconnected, or miswired – see Check #3 in testing the rainDial Transfomer.
- Solenoid or valve is bad – see Check #3 in testing the rainDial Transfomer
- The controller/system has simply failed and should be sent in for repair.
