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
14on. This is called a watering cycle.
