If no sound is heard from the valve, check if the cable from the valve controller has
been cut or broken. Check the connector in the extension tube, make sure it is clean,
dry and the retaining nut is tightened.
1. Verify continuity of the valve solenoid with an ohmmeter, 2 to 6 ohms resistance
is typical.
2. If a sound is heard from the valve, and water does not flow, make sure the water
inlet has pressure.
3. If a sound is heard form the valve, the valve may be stuck, remove the valve and
check for an obstruction, if nothing is found, replace the valve.
4. If no click is heard from the controller, make sure the battery is charged. The
main controller shows the battery charge. If the battery charge is OK, replace the
controller. If the battery charge is low, and the solar exposure has been normal,
replace the battery.

Q: Why after learning a new current wet level, does the system not stop irrigating
right away?
A: Possibly one of the following:
A: If the moisture sensor is moved after learning the wet level, it may be incorrect.
Should redo the learning process.
B: If water is manually added to the soil, then a wet level is learned; the learned
level could be very high, since water could be temporarily accumulated on the
surface. Use the displayed % reading as a guide to determine what reading is correct.
If the learned value is too high, learn the moisture level again later when the soil
dries to the desired level.
C: The LED “Irrigating” is off, but still the system is still irrigating. See FAQ 1,
about valve problems.
D: On the main controller show this zone is irrigation, but has no problems as
described at A and B. then maybe it is sensor problem, please reference questions.
