SPRINKLER SYSTEM FUNDAMENTALS .............................................................................
There are three main components that are involved with all automatic
sprinkler systems that are made today. They are the controller, valves,
and the sprinklers.
The controller is what makes the whole system operate efficiently. It is
technically the brain of the entire system, instructing the valves when to
supply water to the sprinklers and for how long to do so. The sprinklers,
in turn, will direct the water towards the surrounding plants and lawn.
A valve controls a group of sprinklers called a watering station.
These stations are laid out in a fashion according to the type of plant,
the locations of the plants, and the maximum amount of water that
can be pumped to the location. Each valve is connected via wire to the
controller. Here the wire is connected to a number that corresponds to
the valve’s station number.
The controller will operate the valves in numerical sequence, only one at
a time. When a valve has completed its watering; it will switch to the next
station that has been programmed. This process is called the watering
cycle. The information pertaining to the watering times of the individual
stations and the duration of them is called a program.
