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

 An automatic or manual control valve 

located between the irrigation water source and the 

sprinkler system valves and/or backflow preventer.
Normally Closed
A switch or control device that remains closed (off) 

unless energized or activated by a control source.
Normally Open
A switch or control device that remains open (on) unless 

energized or activated by a control source.
Odd/Even Schedule
An Odd or Even watering day schedule based on either 

all odd-or even-numbered calendar days.
Outdoor Timer Model
A timer model with suitable for outdoor installation.
Plug-in Module
A small module that plugs into the ECXTRA that pro-

vides for the connection two additional watering zones. 
Power Supply
The plug-in transformer used to supply 24 VAC to the 

timer from 115 VAC house current.
Pump/Master Valve Control
The timer automatically turns on the Pump/Master Valve 

circuit at the beginning of each watering cycle. 
Pump Delay Time
The Pump/Master Valve control circuit is energized 

before a program watering cycle begins, and is adjust-

able from 1 to 60 seconds. This feature enables the 

pump to pressurize or master valve to open completely 

prior to the start of the watering cycle.

Pump Start Relay
Since the timer is not designed to connect directly to 

the pump, a 24 VAC pump start relay switch must be 

installed between the timer and pump start circuit. 
Rain Delay
This feature enables all watering operations to be 

delayed from 1 to 7 days. For example, rain is forecast 

for the next two days, and instead of turning the timer off 

(and possibly forgetting to turn it back on), a rain delay of 

3 days can be set. At the end of 3 days, the timer auto-

matically resumes watering operation as scheduled.
Rain Sensor
A rain sensor is a remote sensing device that signals the 

timer to postpone automatic watering operation when rain 

has been detected. The timer resumes watering operation 

as scheduled when signaled by the rain sensor.
Rain Sensor Control Switch
The rain sensor control switch is provided to override 

rain sensor operation as needed.
Rain Sensor Configuration Switch
Rain sensors are available in normally open (NO) and 

normally closed (NC) configurations. The type used with 

the ECXTRA is selected with the corresponding switch 

setting.
Scheduling 
Planning how long to water (zone run time), when to 

water (program start time) and which days to water 

(watering days).
