ABOUT YOUR LAWN
Optima's PRT Series Sprinkler Timer is the central unit that controls watering times for your automatic
sprinkler system. The following information provides an overview of how the timer works.
Stations
To meet the different watering requirements of your lawn, trees, flowers, and other landscaping, you
can divide your yard into separate areas called "stations" or "zones".* Each "station" has one valve that
controls multiple spray heads or sprinklers. For example, if you have 4 valves, you can divide your lawn
into 4 "stations". See the figure below. (You cannot link more than one valve to one "station.") You can
however, select a different length of watering time for each "station".
* In the sprinkler industry, the terms "stations” and “zones” have the same meaning.
