The three main components of every automatic sprin-kler system are the timer, zone control valves andsprinklers.

The timer is the brain of the system, telling the controlvalves when and how long to supply water to the sprin-klers. The sprinklers direct and control the water appliedto the lawn and plants.

Each valve controls a specific group of sprinklers calleda watering zone. The zones are generally laid out andinstalled according to the type of plant material to bewatered, the location of the plant within the landscapeand the maximum amount of water which can be sup-plied. Each valve is connected to a numbered terminalwithin the timer, identifying it as zone 1, zone 2, etc.

The timer operates the zones in order, one at a time. In other words, one zone would water completelybefore another zone would turn on. This is called awatering cycle. The information stored in the timermemory which determines when and how long thezones will water is called a program.

The next section of this guide is very important. Itexplains what a program is and how the ECx controlsthe operation of the sprinkler system.

A watering program requires three basic instructions tooperate automatically:• What days to water –called watering days• When to water – called a program start time• How long to water – called valve run time

The following example illustrates how a typical wateringprogram could be set for the sprinkler system shown onthe previous page.

Example: The program start time is set for 5:00 AM. Lawnzones 1 and 2 each have a run time of 10 minutes andlawn zone 4 is set to run for 20 minutes. Note that zones3 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 1sprinklers run for 10 minutes and shut off. Zone 2 sprin-klers turn on, run for 10 minutes and shut off. The timerskips zone 3 and turns on zone 4, which runs for 20 min-utes and shuts off. Zone 5 is skipped and the wateringcycle ends at 5:40 AM.

As you can see from this example, only one programstart time was needed to operate three different zones.

Because of variations in plant watering needs, the ECxprovides three separate programs. The programs, calledA, B and C, are completely independent of one another– like having three timers in one housing.

Using more than one program for example, would enablelawn zones to be watered every day on program A,shrub zones to run on on Monday, Wednesday and Fri-day on program B, and drip irrigation to soak the flowerbeds 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 itmeets your needs. The other programs can remainturned off until you need to use them.

Watering Program Diagram

This section covers in detail each of the three parts of awatering program: watering days, program start timesand valve run times.

Selecting Watering Days

The ECx provides four options for scheduling wateringdays: Calendar, Interval Odd/Even and Off.

Calendar Schedule

A Calendar schedule enables you to select specific daysof the week to water, for example, Monday, Wednesdayand Friday. This is a seven-day schedule which starts onSunday and ends on Saturday.

This illustration shows howa Calendar schedule wouldbe displayed when the con-trol 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 dayswithout regard to the actual days of the week. For exam-ple, if you want to water every third day, you wouldselect a 3-day Interval. Interval schedules range from 1-day (watering every day) to 7-day (watering every sev-enth day). Once you have selected an Interval schedule,you can choose which day of the week will be the firstday of the Interval. The number of days in the Interval

determines the available start days. For example, if youhave selected a 3-day Interval and today is Sunday, youmay choose to start the Interval today, Monday or Tues-day.

This illustration shows howan Interval schedule wouldbe displayed. In this exam-ple, program B has a 3-dayInterval schedule which willstart on Monday.

Odd/Even Schedule

The Odd/Even schedule enables you to select odd oreven numbered days of the month as watering days.

This illustration shows howan Odd day schedule wouldbe displayed.

Program Off

Selecting Off suspends the operation of the programwhen it is not needed. Turning the program Off does notalter or erase the watering schedule information of theprogram, it simply places the program on hold until it isneeded.

This illustration shows how aprogram would be displayedif its watering day scheduleis turned Off. In this exam-ple, program C is Off.

Selecting Program Start Times

A program start time is the time of day you select tobegin an automatic program watering cycle. It is important to remember that a program onlyrequires one start time to operate automatically.When a program starts, each zone assigned to the pro-gram will water in numerical order, one at a time for itsset run time.

Sometimes it is necessary to run a watering programmore than one time per day. For example, when growinga new lawn. The ECx enables each program to have upto four separate start times per day.

Program start times are numbered 1 through 4. Thesenumbers are shown at the top of the display next to thestart time symbol when the control dial is in theSET PROGRAM START TIMES position and indicate howmany start times are currently set for the program.

This illustration shows howa program start time is displayed. In this example,program A has one starttime (start time number 1)set for 5:00 AM.

Setting the Valve Run Time

A valve run time is the length of time the zone (controlledby the valve) will water during the program wateringcycle. The run time for each valve 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 valverun time. If the run time for a valve is turned Off in a pro-gram, it will not operate during the program wateringcycle. This is how the ECx enables you to assign water-ing zones to different programs.

All zones assigned to the program are shown on thelower portion of the display when the control dial is in the SET VALVE RUN TIMES position.

This illustration shows how a valve run time is displayedfor a program. In this exam-ple, zones 1–6 are assignedto program A. Zone 1 has a10-minute valve run timeand the valve for zone 2 isset to run for 25 minutes.

The valve run time being displayed is identified by theflashing zone number.

Flashing

It is always helpful to plan your watering schedule beforebeginning the programming steps. You will have a recordof your watering schedule and zone locations which canbe kept with your ECx after it is installed. A wateringschedule form is provided on page 12 for you to fill out.When you have finalized your schedule, transfer the infor-mation to the watering schedule decal provided on theinside of the cabinet cover.

▼ Guidelines For Watering

There are several factors to be considered when decid-ing when and how long to water. For example, the com-position of your soil, the part of the landscape beingwatered, climate conditions and the type of sprinklersbeing used. Because of these variables, we cannot giveyou an exact schedule to follow, but here are some gen-eral 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 thistime and the water can soak into the plant root zonewhile evaporation is minimal. Watering during mid-dayor in the evening may cause plant damage or mildew.

▼ Watch for signs of under- or over-watering and makeprogram adjustments immediately.

Filling Out the Watering Schedule Form

When filling out this form, use a pencil so changes can beeasily made.

Refer to the example form shown on the opposite pageand fill out your form in a similar manner with the follow-ing information:

• Location - Identify the location of each watering zoneand the type of plant being watered.

Note: Enter the following information for each pro-gram. If the program is not needed, leave its informa-tion 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 Intervalnumber. For Odd or Even days, simply mark theappropriate box.

• Valve Run Time - Indicate the amount of run time (1 minute to 4 hours) for each zone. Write “Off” for anyzone which you do not want to operate in the program.

• Program Start Times - Indicate the time of day tostart the program. Each program can have 1 to 4 starttimes per watering day.

Note: The ECx will run only one watering cycle at atime. Therefore, when using multiple start times withina program or when using multiple programs, makesure that each watering cycle will be able to run com-pletely before the next watering cycle is scheduled tostart. A program start time that occurs while a wateringcycle is in progress will be delayed until the currentwatering cycle is finished.

(Example)

The ECx timer features the ability to be fully programmedbefore installation. Installing its 9-volt battery brings theECx to life, so you can program your new timer while inthe comfort of your home.

The ECx can use either type of 9-volt battery: Alkaline orrechargeable Nickel Metal Hydride (Ni-MH). The Alkalinebattery provided will keep the timer’s clock and program-mable memory functioning for about 72 hours and shouldbe replaced every year. A fully-charged Ni-MH battery willlast about 24 hours, but is continuously recharged to pro-vide service for many years.

If your home has frequent power interruptions, installing arechargeable Ni-MH battery is recommended.

Note: The battery does not supply power to operate thezone control valves; power from the transformer must besupplied.

1. Pull outward on the lower housing cover handle toremove. Locate the battery clip and attach it to thebattery terminals.

2. Insert the battery into the timer housing as shown inFigure 1.

3. Slide the battery switch (14) to the left (ALK) for Alka-line or right (RCHG) to activate the Ni-MH batterycharging circuit. See Figure 2.

Caution: The battery charger switch must be setcorrectly. Damage to the controller can result froman Alkaline battery which may fail if charged.

4. Press the +/ON button to stop the display from flash-ing. The colon (:) will continually flash while displayingthe time and during watering operation.

WARNING:

Always replace battery with the same or equivalenttype. Dispose of used batteries according to the battery manufacturer’s recommendations.

24-Hour Clock Mode

The ECx is set to displaytime in the 12-hour clockmode. If you prefer to use a 24-hour clock mode (military time), select thisoption by removing the12/24 Hour SelectorJumper (4). To store thejumper, install it on one pinas shown. See Figure 3.

15-Second Run Delay

The 15-second run delay feature is useful for sprinklersystems utilizing a pump or master valve. For example, a pump usually requires a few seconds to build pressureafter first starting. With the 15-second run delay selected,the pump would be running (or the master valve wouldopen) 15 seconds before the first zone begins watering.A 15-second delay would also occur between zone oper-ations. This helps ensure that one valve is closed beforeanother valve opens. Note: A 2-second run delay will occur if this option is notselected.To select the 15-second delay option, remove the DelaySelector Jumper (5).

Odd/Even Watering Days

If you plan to use an Odd or Even day watering schedule,remove the Odd/Even Selector Jumper (6) for this option.

The ECx has a permanent watering schedule within itsmemory to assist you in two ways. First, it will restorewatering operation in case your watering program is lostdue to a power interruption lasting longer than the bat-tery life. This prevents your landscape from going unwa-tered 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 tooperate your sprinklers. Just set the current timeand day and your ECx will be ready to operate auto-matically.

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 scheduleset to water every day. One program start time is set for5:00 AM and a run time of 10 minutes is set for eachzone. Programs B and C are turned Off and have noprogram start times or run times.

Note: An optional feature is provided which enables theThe ECx memory to be reset to the permanent programor cleared completely if you choose. If you do not want touse this option, skip the next procedure “Resetting TheTimer Memory” and continue at page 16 to begin pro-gramming.

The ECx program memory can be reset to the perma-nent program values or cleared completely at any timewithout removing power.

Resetting the permanent program erases all user inputand replaces it with the permanent program values.

Clearing the program memory sets all program values toOff (i.e., no active days, program start times or zone runtimes). You may find that this simplifies programming thetimer if your watering requirements are quite differentthan the permanent values.

Note: When power is first applied, the ECx will alwaysreset to the permanent program values.

The ECx timer has three modes of operation: Automatic,Manual and Off. In the Automatic mode the timer tracksthe time and day and operates the automatic wateringschedules. The Manual mode enables the watering pro-grams to be started and controlled manually at any time.The Off mode shuts off all watering activity and preventsany zones from operating automatically or manually.

The Rain Delay and Season Adjust control features areprovided to enable quick, temporary changes in operationto help compensate for variables in weather and season.

Each of the operating modes and control features areexplained in this section of the guide and can be foundon the following pages:

• Automatic Operation, page 27• Manual Operation, page 28• Watering Control Features, page 29• Turning Off The ECx, page 30• Using the Rain Delay Feature, page 30• Using the Season Adjust Feature, page 31

In the Automatic mode, the ECx keeps track of the cur-rent time, day of the week and the automatic wateringprogram schedule. Automatic operation will occur when-ever a programmed watering day and start time matchthe current time and day.

The Automatic mode is selected when the control dial isin the AUTO/ON position. While in the automatic mode,the display will show two types of information: status andoperation.

This illustration shows thestatus display. In thisexample the current time is2:45 PM and the currentday is Monday. ProgramsA and B are active on Monday.

When watering starts, the operating display appears andis shown for the duration of the program.

In this example, program Ais operating. Zone 1 iswatering and has 10 min-utes of run time remaining.Zones 2, 3 and 4 will oper-ate during this program.

Note: If the control dial remains in any other position(except OFF) for more than 8 minutes, the timer reverts tothe Automatic mode.

Note: The position of the PROGRAMS switch does notdetermine which program will run during automatic con-troller operation. In other words, if a program has anassigned watering day schedule, start time and a zonewith run time, it will operate automatically regardless ofthe position of the PROGRAMS switch.

Watering Control Features

29

When the control dial is turned to the OFF position, thetimer immediately shuts off any watering operation cur-rently in progress. Leaving the control dial in the OFF

position will prevent all automatic and manual wateringoperations. The timer will continue to track the currenttime and day of the week.

For extended shutdown of the sprinkler system leave thecontrol dial in the OFF position.

The word OFF will be displayed for 8 minutes.

Automatic operation is resumedby turning the control dial to theAUTO/ON position.

This feature enables all watering operations to bedelayed from 1 to 7 days. For example, rain is forecast inyour area for the next two days. Instead of turning thetimer off (and possibly forgetting to turn it back on), arain delay of 3 days can be easily entered. At the end of3 days, the timer will resume automatic operation asscheduled.

Turn the control dial to the RAIN DELAY position. Therain delay display will begin alternating with the auto-matic status display.

To set the number of rain delay days, press the +/ON

or –/OFF button until the desired number (1–7) isflashing.

Return the control dial the control to the AUTO/ON

position.

Note: The rain delay number will automaticallydecrease as each day passes. When the numberreaches 0 (zero), automatic operation will resume atthe next scheduled start time.

To cancel the rain delay, turn the control dialmomentarily (3 seconds) to the OFF position.

Changes in season and temperature generally require achange in valve run time to maintain a healthy landscapeand conserve water. The season adjust feature enablesyou to change the run time of all valves assigned to aprogram, simultaneously up or down, in 10% increments– with just the press of a button. Adjustments can bereduced to 10% or increased to 200% of the programmedrun time of each valve.

A 50% setting, for example, would decrease a 20-minutevalve run time to 10 minutes. Increases however, work alittle differently. With any adjustment above 100%, theECx will first increase the run time by the adjustmentpercentage, then split the time in half and run the water-ing program twice. This allows the water to soak-ininstead of pooling or running off. For example, adjustingto 150% would first increase a 20-minute valve run timeto 30 minutes, then split the time in half and run twowatering cycles back-to-back with 15 minutes in eachoperation. During operation the % symbol will flash toindicate a multiple watering operation.

Note: All valve run times are retained in the timer memo-ry and returned to their set value when the season adjustis reset to 100%. The only time a valve run time willappear 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 +/ON or –/OFF until the desired adjustmentvalue is flashing.
