Manual timer - Great for testing that your wiring works! You can also use this to give your plants a good water if you feel they are under-watered before you adjust the timing.

Overlaps are sometimes not practical due to water pressure limitations as well as limitations on the solenoid valve power supply.

Time overlap detection - ezSprinkle will still allow you to overlap area times, but an indicator warns you of the overlap.

This will save many people a lot of time. The effect is an easy to configure back-to-back watering program.
