Automatic Sprinkler System Basics
The three main operating components of every auto-
matic 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 water-
ing schedule that you set. The watering schedule deter-
mines 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 fol-
low three different watering schedules. It is important to
remember that you only need to use one program to oper-
ate 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
on. This is called a watering cycle.
