Timer Components
The three main components of every automatic sprinkler
system are the timer, zone control valves and sprinklers.
The timer is the brain of the system, telling the control
valves when and how long to supply water to the sprinklers. The sprinklers direct and control the water applied to
the lawn and plants.
Each valve controls a specific group of sprinklers called
a watering
zone. The zones are generally laid out and
installed according to the type of plant material to be
watered, the location plant within the landscape and the
maximum amount of water which can be supplied. Each
valve is connected to a numbered terminal within the
timer, identifying it as Zone 1, Zone 2, etc.
The timer operates the valves in order, one at a time. In
other words, one zone would water completely before
another zone would turn on. This is called a watering
cycle. The information stored in the timer memory which
determines when and how long the zones will water is
called a
program.
The next section of this guide is very important. It
explains what a program is and how the ECx controls the
operation of the sprinkler system.

A watering program requires three basic instructions to
operate automatically:
• What days to water –called
watering days
• When to water – called a program start time
• How long to water – called zone run time
The following example illustrates how a typical watering
program could be set for the sprinkler system shown on
the previous page.
Example: The program start time is set for 5:00
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 exclud-
ed from this program. (These zones will be set to oper-
ate on separate programs).
As shown in the watering program diagram, at 5:00
AM
the timer starts the program watering cycle. Zone 1
sprinklers run for 10 minutes and shut off. Zone 2 sprin-
klers turn on, run for 10 minutes and shut off. The timer
skips zone 3 and turns on zone 4, which runs for 20 min-
utes and shuts off. Zone 5 is skipped and the watering
cycle ends at 5:40
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 ECx
provides three separate programs. The programs, called
A, B and C, are completely independent 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 ECx offers the multiple program feature,
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.

Watering Program Diagram
This section covers in detail each of the three parts of a
watering program – watering days, program start times
and zone run times.
Selecting Watering Days
The ECx provides three options for scheduling watering
days: Calendar, Interval and Off.
Calendar Schedule
A Calendar schedule enables you to select specific days
of the week to water, for example, Monday, Wednesday
and Friday. This is a seven-day schedule which starts on
Sunday and ends on Saturday.
This illustration shows how a Calendar schedule would
be displayed when the control dial is in the
SET WATER-
ING DAYS position.
In this example, program
A
has watering days set for MO
(Monday), WE (Wednesday)
and
FR (Friday).
Interval Schedule
An Interval schedule enables you to set watering days
without regard to the actual days of the week. For example, if you want to water every third day, you would
select a 3-day Interval.
Interval schedules range from 1-day (watering every
day) to 7-day (watering every seventh day). Once you
have selected an Interval schedule, you can choose
which day of the week will be the first day of the Interval.
The number of days in the Interval determines the available start days. For example, if you have selected a 3day Interval and today is Sunday, you may choose to
start the Interval today, Monday or Tuesday.
This illustration shows how
an Interval schedule would
be displayed. In this example, program
B has a 3-day
Interval schedule which will
start on Monday.
Program Off
Selecting Off suspends the operation of the program
when it is not needed. Turning the program Off does not
alter or erase the Calendar or Interval schedule information of the program, it simply places the program on hold
until it is needed.
This illustration shows how a
program would be displayed
if its watering day schedule
is turned Off. In this example, program
C is Off.

Selecting Program Start Times
A program start time is the time of day you select to
begin an automatic program watering cycle.
It is important to remember that a program only
requires one start time to operate automatically.
When a program starts, each zone assigned to a program will water in numerical order, one at a time for its
set run time.
Sometimes it is necessary to run a watering program
more than one time per day. For example, when growing
a new lawn. The ECx enables each program to have up
to four separate start times per day.
Program start times are numbered 1 through 4. These
numbers are shown at the top left of the display next to
the start time symbol when the control dial is in the
SET PROGRAM START TIMES position and indicate how
many start times are currently set for the program.
This illustration shows how
a program start time is
displayed. In this example,
program
A has one start
time (start time number 1)
set for 5:00
AM.
Setting The Zone Run Time
A zone run time is the length of time the zone (controlled
by the valve) will water during the program watering
cycle. The run time for each zone can be set from Off
(no run time) to 4 hours, in one-minute increments.
A zone is
assigned to a program when it is given a run
time. If the run time for a zone is turned Off in a program,
it will not operate during the program watering cycle.
This is how the ECx enables you to assign watering
zones to different programs.
All zones assigned to the program are shown on the
lower portion of the display when the control dial is in
the
SET ZONE RUN TIMES position.
This illustration shows how
a zone run time is displayed
for a program. In this example, zones 1–6 are assigned
to program
A. Zone 1 has a
10-minute run time and
zone 2 is set to run for 25
minutes.
The zone run time being
displayed is identified by the
flashing zone number.

It is always helpful to plan your watering schedule on
paper before beginning the programming steps. You will
have a record of your watering schedule and zone locations which can be kept with your ECx after it is installed.
A watering schedule form is provided on page 12 for you
to fill out.
••
Guidelines For Watering
There are several factors to be considered when deciding when and how long to water. For example, the content of your soil, the part of the landscape being watered,
climate conditions and the type of sprinklers being used.
Because of these variables, we cannot give you an exact
schedule to follow, but here are some general watering
guidelines to help you get started.
• Water early in the morning, one to two hours before
sunrise. You will have the best water pressure at this
time and the water can soak into the plant root zone
while evaporation is minimal. Watering during mid-day
or in the evening may cause plant damage or mildew.
• Watch for signs of under- or over-watering and make
program adjustments immediately.
Filling Out The Watering Schedule Form
When filling out this form, use a pencil so changes can be
easily made. Carefully remove the page from the booklet
to use as a guide during programming. After installing the
timer, fold the form in half and store it in the pocket
behind the timer.
Refer to the example form shown on the opposite page
and fill out your form in a similar manner with the following information:
•
Location - Identify the location of each watering zone
and the type of plant being watered.
Note: Enter the following information for each pro-
gram. If the program is not needed, leave its information column blank.
•
Watering Day Schedule - For a Calendar schedule,
indicate which day(s) of the week watering is desired.
For an Interval schedule indicate the desired Interval
number.
•
Zone Run Time - Indicate the amount of run time
(1 minute to 4 hours) for each zone. Write “Off” for any
zone which you do not want to operate in the program.
•
Program Start Times - Indicate the time of day to
start the program. Each program can have 1 to 4 start
times per watering day.

The ECx timer features the ability to be fully programmed
before installation. Installing its 9-volt battery brings the
ECx to life, so you can program your new timer while in
the comfort of your home.
The ECx can use either type of 9-volt battery: Alkaline or
rechargeable Nickel-Cadmium (NiCd). The Alkaline battery provided will keep the timer’s clock and programmable memory functioning for about 72 hours and should be
replaced every year. A fully-charged NiCd battery will last
about 24 hours, but is continuously recharged to provide
service for many years.
If your home has frequent power interruptions, installing a
rechargeable NiCd battery is recommended.
Note: The battery does not supply power to operate the
zone control valves; power from the transformer must be
supplied.
1. Slide the lower housing cover toward the bottom of
the timer to remove. Locate the battery clip and attach
it to the battery terminals.
2. Insert the battery into the timer housing as shown in
Figure 1.
3. Slide the battery switch (7) to the left for Alkaline or
right to activate the NiCd battery charging circuit.
See
Figure 2.
Caution: The battery switch (7) must be set correctly.
Damage to the timer can result from an Alkaline battery which may fail if charged.
4. Press the +/ON button to stop the display from flashing. The colon (
:) will continually flash while displaying
the time and during watering operation.

24-Hour Clock Mode
The ECx is set to display time in the 12-hour clock mode.
If you prefer to use a 24-hour clock mode (military time)
select this option by following the steps below.
15-Second Run Delay
The 15-second run delay feature is useful for sprinkler
systems utilizing a pump or master valve. For example, a
pump usually requires a few seconds to build pressure
after first turning on. With the 15-second run delay
selected, the pump would be running (or the master
valve would open) 15 seconds before the first zone
begins watering. A 15-second delay would also occur
between zone operations. This helps ensure that one
valve is closed before another valve opens.
Note: A 2-second run delay will occur if this option is not
selected.
Caution: To prevent timer
damage, ensure transformer is disconnected
during this procedure.
1. Using small wire cutters,
clip jumper (13) to select
24-hour clock mode. Clip
jumper (12) to select
15-second run delay.
The ECx has a permanent watering schedule within its
memory to assist you in two ways. First, it will restore
watering operation in case your watering program is lost
due to a power interruption lasting longer than the battery life. This prevents your landscape from going unwatered if the power outage occurs while you are away.
Secondly,
if you do not want to program your ECx,
you may use the permanent watering schedule to
operate your sprinklers. Just set the current time
and day and your ECx will be ready to operate automatically.
The permanent watering schedule operates as follows:
When power is applied, the timer clock is set to 12:00
AM
Sunday. Program A has a Calendar watering schedule
set to water every day. One program start time is set for
5:00
AM (5:00) and a run time of 10 minutes is set for
each zone. Programs
B and C are turned Off and have
no program start times or run times.
Note: An optional feature is provided which enables the
The ECx memory to be reset to the permanent program
or cleared completely if you choose. If you do not want to
use this option, skip the next procedure “Resetting The
Timer Memory” and continue at page 16 to begin programming.

The ECx program memory can be reset to the permanent program values or cleared completely at any time
without removing power.
Resetting the permanent program erases all user input
and replaces it with the permanent program values.
Clearing the program memory sets all program values to
Off (i.e., no active days, program start times or zone run
times). You may find that this simplifies programming the
timer if your watering requirements are quite different
than the permanent values.
Note: When power is first applied, the ECx will always
reset to the permanent program values.
To Reset The Permanent Program (Figure 3)
Turn the control dial to the OFF position. OFF will be
displayed.
Press the +/ON and –/OFF buttons at the same time
until CLR is displayed.
Return the control dial to the
AUTO/ON position.
To Clear The Memory (Figure 4)
Turn the control dial to the OFF position. OFF will be
displayed.
Press the +/ON and –/OFF buttons at the same time
until CLR 0 is displayed.
Return the control dial to the

Note: The ECx timer is not weather resistant and
must be installed indoors or in a protected area.
For
outdoor installation, an optional weather-resistant outdoor cabinet (model # 53335) is available.
1. Select a location for the timer within 4' (1.2m) of an
electrical outlet to enable the transformer wires to
easily reach. Make sure the outlet is not controlled by
a light switch.
2. Remove the mounting bracket attached to the back
of the timer housing by pulling the lower edge of the
bracket away and downward from the timer housing.
3. Place the mounting bracket (A) against the wall align-
ing the top edge at about eye level. Drive three 1"
(25mm) wood screws (B) into the wall through the
three holes provided in the bracket.
Note: If you are installing the bracket on drywall or
masonry, install screw anchors (C) to prevent screws
from loosening.
4. Align the slotted openings on the back of timer hous-
ing with the mounting bracket tabs. Slide the timer
downward to engage the tabs.

1. Route the valve control wires between the valves and
the timer.
Note: Using 18 AWG (0.75 mm2) multi-wire sprinkler
valve connection cable is recommended. This cable
is insulated for direct burial and is color-coded to simplify installation.
2. Attach the white color-coded wire from the cable to
one
wire from each valve solenoid. (Either solenoid
wire can be used for this connection.) This is called
the
valve common wire.
3. Attach a separate cable wire to the remaining wire
from each valve solenoid. Make a note of the wire
color code used for each valve and the watering zone
it controls. You will need to have this information
when connecting the valve wires to the timer.
4. Use screw-on wire fasteners to secure each wire con-
nection. Waterproof all connections with grease caps
or simular insulation method.
5. Route the wire cable into the timer. Strip insulation
back 1/2" (13mm) from all cable wires.
Note: The ECx has snap-in wire terminals. To attach
wires, simply raise the lever, insert the stripped wire,
and press the lever down to secure.
6. Referring to the Timer Components on page 5 and the
diagram above, secure the valve common wire to the
terminal labeled COM (11). Connect the individual
zone valve wires to the appropriate zone module terminals (14). Connect the master valve wire (if applicable) to the terminal labeled PUMP/MV (10).
Note: Connecting a master valve (or pump relay) is
optional and may not be required in your sprinkler
system.

The Toro Rain Switch (model # 53221) is a remote rain
sensing device which can be connected directly to your
ECx to automatically interrupt watering during rain.
A sensor bypass switch is provided in the ECx which
enables the Rain Switch operation to be turned On and
Off.
When the Rain Switch absorbs rain water it automatically
signals the ECx to suspend all watering operations. The
“No Watering” symbol will appear in the upper right
corner of the display until the Rain Switch drys out and
automatically resets. The “No Watering” symbol will dis-
appear and timer operation will resume as programmed.
1. Route the wire cable from Toro Rain Switch into the
timer housing with the valve wires.
2. The Rain Switch cable has four wires: two copper
wires and two silver wires. Only two of the wires are
used. Connect the heavier 18 AWG (0.75mm
2
) copper
wire and the thin 24 AWG (0.50mm
2
) silver wire to the
terminals labeled SENSOR (8). Trim off the remaining
two cable wires.
3. Set Sensor Switch (6) as required: ON allows the
Rain Switch to interrupt watering; OFF bypasses the
Rain Switch input.

The ECx timer has three modes of operation: Automatic,
Manual and Off. In the Automatic mode the timer tracks
the time and day and operates the automatic watering
schedules. The Manual mode enables the watering programs to be started and controlled manually at any time.
The Off mode shuts off all watering activity and prevents
any zones from operating automatically or manually.
The Rain Delay and Season Adjust control features are
provided to enable quick, temporary changes in operation
to help compensate for variables in weather and season.
Each of the operating modes and control features are
explained in this section of the guide and can be found
on the following pages:
• Automatic Operation, page 26
• Manual Operations, page 27 & 28
• Turning Off The ECx, page 29
• Using the Rain Delay Feature, page 29
• Using the Season Adjust Feature, page 30
In the Automatic mode, the ECx keeps track of the current time, day of the week and the automatic watering
program schedule. Automatic operation will occur whenever a programmed watering day and start time match
the current time and day.
The Automatic mode is selected when the control dial is
in the
AUTO/ON position. While in the automatic mode,
the display will show two types of information:
status and operation.
This illustration shows the
status display. In this
example the current time is
2:45
PM and the current
day is Monday. Programs
A and B are active on
Monday.
When watering starts, the operating display appears and
is shown for the duration of the program.
In this example, program
A
is operating. Zone 1 is
watering and has 10 minutes of run time remaining.
Zones 2, 3 and 4 will operate during this program.
Note: If the control dial remains in any other position
(except
OFF) for more than 8 minutes, the timer reverts to
the Automatic mode.
The
PROGRAMS switch is not functional in the Automatic
Mode.

Watering Contr ol Features
28
When the control dial is turned to the OFF position, the
timer immediately shuts off any watering operation currently in progress. Leaving the control dial in the
OFF
position will prevent all automatic and manual watering
operations. The timer will continue to track the current
time and day of the week.
For extended shutdown of the
sprinkler system leave the control
dial in the
OFF position.
The word OFF will be displayed
for 8 minutes. The automatic status display will then appear with
the “No Watering” symbol as
shown in this illustration.
Automatic operation is resumed by turning the control
dial to the
AUTO/ON position.
This feature enables all watering operations to be
delayed from 1 to 7 days. For example, rain is forecast in
your area for the next two days. Instead of turning the
timer off (and possibly forgetting to turn it back on), a
rain delay of 3 days can be easily entered. At the end of
3 days, the timer will resume automatic operation as
scheduled.
Turn the control dial to the
RAIN DELAY position. The
rain delay display will begin alternating with the automatic status display.
To set the number of rain delay days, press the
+/ON
or –/OFF button until the desired number (1–7) is
flashing.
Return the control dial the control to the
AUTO/ON
position.
Note: The rain delay number will automatically
decrease as each day passes. When the number
reaches 0 (zero), automatic operation will resume at
the next scheduled start time.
To cancel the rain delay, turn the control dial
momentarily (3 seconds) to the
OFF position.

Changes in season and temperature generally require a
change in zone run time to maintain a healthy landscape
and conserve water. The season adjust feature enables
you to change the run time of all zones assigned to a program, simultaneously up or down, in 10% increments –
with just the press of a button. Adjustments can be
reduced to 10% or increased to 200% of the programmed
run time of each zone.
A 50% setting, for example, would decrease a 20-minute
zone run time to 10 minutes. Increases however, work a
little differently. With any adjustment above 100%, the
ECx will first increase the run time by the adjustment
percentage, then split the time in half and run the water-
ing program twice. This allows the water to soak-in
instead of pooling or running off. For example, adjusting
to 150% would first increase a 20-minute zone run time
to 30 minutes, then split the time in half and run two
watering cycles back-to-back with 15 minutes in each
operation. During operation the % symbol will flash to
indicate a multiple watering operation.
Note: All zone run times are retained in the timer memory
and returned to their set value when the season adjust is
reset to 100%. The only time a zone run time will appear
changed is during operation.
Turn the control dial to the
SEASON ADJUST position.
The season adjust display will be shown and 100%
will be flashing.
Check the
PROGRAMs switch setting. If necessary,
reposition the switch to select the desired program.
Press the

value is flashing.
