Toro EC-XTRA Landscape Timer, 6-Zone (53794) Installation Guide

A watering schedule consists of three basic instructions:  

• What days to water –called watering days 

• When to water – called a start time 

• How long to water – called a run time 
The following example illustrates how a program has a 

watering schedule set for the sprinkler system shown on  

page 14. The diagram on the right depicts how the pro-

gram runs the watering schedule to complete a watering 

cycle
The program start time is set for 4:00 

am

. Lawn zones 1 

and 2 each have a run time of 10 minutes and lawn zone 

4 is set to run for 20 minutes. Note that zones 3 and 5 

water shrubs and flowers and have been excluded from 

this program. (These zones will be scheduled to operate 

on a another program.)
As shown in the Watering Program Diagram, at 4:00 

am

 

the timer starts the program watering cycle. Zone 1 sprin-

klers run for 10 minutes and shut off. Zone 2 sprinklers 

then turn on, run for 10 minutes and shut off. The timer 

skips zone 3 then turns on zone 4, which runs for 20  

minutes and shuts off. Zone 5 is skipped and the watering 

cycle ends at 4:40 

am

. 

As you can see from this example, only one program 

start time was needed to operate three different zones.
Because of variations in plant watering needs, the  

ECXTRA provides three separate programs. The  

programs, called A, B and C, are completely indepen-

dent of one another – like having three timers in one 

housing. 

Using more than one program for example, would enable 

lawn zones to be watered every day on program A, 

shrub zones to run on on Monday, Wednesday and  

Friday on program B and drip irrigation to soak the flower 

beds every three days on program C. 
Although the ECXTRA offers the multiple program fea-

ture, you may want to have all zones on one program 

if it meets your needs. The other programs can remain 

turned off until you need to use them.
