Single Station
Figure 3 shows a Water Saving Irrigation Sensor operating a single solenoid valve. The Water Saving Irrigation Sensor is mounted directly under the line of sprinklers or drippers it's controlling.
If you want to only irrigate at certain times you can ad an Irrigation Controller/Timer as shown in Figure 3. In this case the Irrigation Controller/Timer can be any type of Brand Name irrigation controller. Or it could be a common electronic time clock controlling a 240 v to 24 v step-down transformer. The Water Saving Irrigation Sensor and the 24 v solenoid valve are wired in series.
This installation method can also be used with the multi-station controller/timer shown in Figure 5.

Remote Sprinkler or Dripper
You can install the Water Saving Irrigation Sensor near your main irrigation controller/timer and use a remote sprinkler or a special remote dripper to supply it with water. This saves on electrical wiring.
Figure 4 shows a Water Saving Irrigation Sensor operating a single solenoid valve. The Water Saving Irrigation Sensor is mounted remotely from the main sprinklers or drippers. However, it still has a sprinkler or dripper installed above it, so that will collect water while irrigating.
The sprinkler can be replaced by a special remote dripper. The special remote dripper automatically fills the Water Saving Irrigation Sensor's water reservoir at the end of the irrigation cycle without wasting water. This enables the Water Saving Irrigation Sensor to be used with drip irrigation systems. This installation method can also be used with the multi-station controller shown in Figure 5.

Figure 5 shows a Water Saving Irrigation Sensor in a typical multistation automatic irrigation system. It is installed at the end of the last irrigation line.
The Water Saving Irrigation Sensor is connected in series with all of the Common wires between the solenoid valves and the irrigation controller. When installed this way the Water Saving Irrigation Sensor will inhibit all subsequent programmed irrigation cycles after the last valve has operated and watered. Irrigation recommences when the water in the Water Reservoir evaporates.
