Automatic Sprinkler System Basics
The three main operating components of every automatic
sprinkler system are the timer, control valves and
sprinklers /drip emitters.
The timer is the brain of the system, signaling the control
valves when to start and stop the flow of water to the
sprinklers. The sprinklers and/or drip emitters apply the
water.
Each valve controls a group of sprinklers called a water-
ing zone. The watering zones should be planned and
installed according to the type of plant material being
watered, the sun/shade conditions, the amount of water
delivered by the sprinkler/emitter and the available water
flow and pressure.
The timer controls automatic operation based on a
watering schedule that you set. The watering schedule
determines when and how long each zone will be
watered. The ECXTRA provides three independent
watering programs (called A, B and C). Each program
can have it's own watering schedule. This feature
enables each zone to follow three different watering
schedules. It is important to remember that you only
need to use one program to operate the timer. The two
remaining programs are there if you need them.
When an automatic program starts, the valves operate
one at a time in numeric order. In other words, one zone
would water completely before another zone would turn
14
on. This is called a watering cycle.
