THANK YOU for purchasing the Smartzoneril EZ electronic irrigaiion
controller. You'll soon discover why we've dubbed it the "E2". We are
confident it will be ihe easiest and most reliable controller you will ever use.
It's so "EZ", you'll probably be able to install and program this feature-packed
controller without instructions. However, belore instailing and programming
the controller, we recommend you read these instructions carefully to take full
advantage ol all the SmartzoneirM EZ has to offer.
lf you have questions, problems or comments on your new Smartzonerrl EZ,
please call our Technical Services Department toll-free at 1-800-NELSON8.

INSTALLATION INSTRUCTIONS
TerminalStrip
Al zone, pump and sensor wire connections rnade jnside the SmartzonerM EZ utilize tool-less
connectors. Press on lhe terminal strrp lever wilh a pen or small screwdriver and insert ihe wrre
nto the botlom. The lerminal strips in the SmartzonerM EZ contro ler accept 14 AWG (1.6 mm)
wire or smaller,
Connecting Master Valve or Pump-Start Relay
The SmartzonerM EZ is equipped with a shared circuil to operate either a purnp start relay or a
master valve. Conneci one wire lrorn the pump sta( relay to COt\,4 (common) on term nal strjp. the
other to PMP/IV]V (pump/rrasler vave) on the termina strip. Fefer to pump-start re ay
mafufaciurers instruct ons for specilic nstalatron deta ls.
Connecting Rain/Moislure Sensor (see figure 2)
The SmartzonerM EZ is equipped to operate a sensor with normally-closed leads. The sensor
port on the SmartzonerM EZ is the frrst tool-less connector on the intercon|ect board (see F gLlre
2). To install a sensor, remove the iactory-instal ecl jumper w re from the sensor connector on the
terminai slrjp and insert the sensor wires. Reier to the sensor rnanufacturer,s instructions jor
specific instal alion detai s.
lf a sensor has suspended watering, the sensor indrcator segnrent will appear on the LCD@.
The symbol wil go off when the sensor has dried out or when the controller is set in one oi the
manual modes (see pages 23-25). The SmartzonerM EZ w l resume operation based on the
selected program.

Connecting Battery and Resetting Controller
Connect one 9V A kaline battery to the baliery clip and ifseri inlo the battery ho der on the back
ol the front panel. The baitery enables the SmartzonerM EZ to be programmed without AC power
and maintains the real time c ock in the event oi a power outage. lt a battery is noi insial ed, the
controller wil lose real time in the event oi a power outaqe. The bal1ery shou d be replaced ofce
a year.
Alter installing the battery, press ihe black reset button on the back oi the front panel lo reset lhe
conlroller (does not affeci prograrn(s)). To reset the controller 10 its defauli settings, press both the
b ack reset button and the SELECT A key simultaneous y. Felease reset bulton before re easing
seleci /i: key. Close ihe front panel, being sure not to damage wires. lf wires are stifJ, you may
lind it helpful to pre-bend them. Tighten the panel screw 1o secure the tronl panel to lhe case.
Pluq in the AC cord for the transformer or turn on the poweT source.
NOTE: Since all programs are stored in non-volatile memory, you will not lose program
settings during a power failure - even if there is no battery installed.
No AC Power Symbol
When AC power is lost, the no AC Power Symbol (@ ) wil be dlsplayed. lf a program is running, it
will stop. Water ng operat ons will resume with the next scheduled program aiter AC is restored.

PROGRAMMING INSTFUCTIONS
Programming Overview
Beiore programming the SmartzonerM EZ, it rnay be helpf!i to become jamlliar with some general
pro9rarn ng ouide'ine.:
. lf a segrnent(s) on the LCD is llashing, it means that it can be changed by the user.
. when using,i:. or !:'keys, hold the buiion three seconds to start a iast scroll.
. Be sure the appropriaie program letter is displayed when you are programming; program
changes are specific to the prograrn lelter displayed on the LCD.
. There is no "ENTER" key. Key-presses and dial settings are stored automatically for you.
. Jf you make a prograrnming change while a prograrn is runnrng, the program lerninales
immediale y. The new program staris at the next slart tirne scheduled.
. When not rLrnning, the controller displays the current time and the current day.
. During manual operations, lhere is a 10 second delay before the operation begins. During this
time, you can change your seitrngs. Each time yoLl make a change, the de ay resels to T0
seconds.
. N,'IANUAL, CYCLE, and 3 N,4INUTE TEST procedures only operate wth ihe program dia set n
the AUTO posltion.
. Afler a test procedure runs, the coniroller reverts back to the AUTO procedure and rur.rs the
next prograrn sched!led.
. The test procedures ignore the sensor connect on; this allows you to waler or tun your
prograrn even if the sensor has suspended operalion.
. Siart tirnes programmed in A, B, or C will rLrn regardtess oi A_ B, C dia positron. programs in
A, B. or C can not overlap siari and stop limes.
PROGHAMMING INSTHUCTIO
Front Panel Layout
Looking ai the front panel (see figure 4), you see a arge LCD, 4 rubber buttons, one large rotary
dial, arld two small roiary dials. The rubber buttons are marked ',SELECT,, and ',ADJUSi' and jre
the heart of Nelson's exctusive SELECT&ADJI.JST'" programmtng. The keys are identrJied
wilh,i.i. for increasing or decreasing the segment youle working on.
SELECT&AOJUSTI; works on ihe principle that you iirsi SELECT what you want to set, and
ADJUST lhe va|ables of what you seleciecj. For example, if you want a run time oi 1O rninutes on
zone 5, you would use the SELECTA.T keys to selecl zofe S and, once on zone 5, you would
use the ADJusT.tiT keys io set the run trme to 1o minutes.
There are instances when only SELECT or only ADJUST is required. They will be explained in

SCHEDULING
A quick note on scheduting and the SmartzonerM Ez ..-
The SmadzonerM EZ controller has three scheduling options:
. WATER DAYS, or daily, lets you choose which days of the week you want to waier (i.e ,
Nlonday, WednesdaY, Friday only).
. ODD/EVEN lells the controller to water on either the odd or even days oi ihe rnonth (i.e , lhe
controller will water on the 31t and the ld when an ODD schedule is chosen)
. INTERVAL walers every X nlmber oi days (from 1 to 30 days) (i e , water every 3 days' water
every l0 days, etc.). A va ue of l in an interval schedu e n.eans to water every day When
uslng the interval option, yo! have the llexibillty to lell the contro ler what day to start the
lnterval program on (up to 30 days oul).
PROGRAMMING INSTRUCTIONS
NOTE: The MODE dial must be in the "Program" position to set a schedule'
When the dla is sei io any oi lhe scheduling options, lhe LCD will dlsplay the currently scheduled
program (deiau t is a 1 day interval schedule with today's date ior a stari date) Be sure the
PBOGRANI dial is set on the program you wanl to change (A, B, or C) and that yotr want to
change the current schedu e. A schedLllng oplion is chosen atter you press a button, either

ADVANCED FEATURES
The Smartzonerir EZ incorporates three manual/test procedures for checking the function of the
controler or alowing you to bypass the current program to water immediately. The iolowing
section will show you how to set up the conlroler to:
. run a 70ne manually
. run a progtan narLaly
. run a 3 mrnlle tesl Of every proqrarnmed zone
NOTE: All test procedures ar€ run wlth the l\,lODE dial in the AUTO position. This allows lhe
contro ler 10 reset to the AUTO setting afler running a manual/test procedure. lt also
allows you the ability to walk away from the controller afler sening up a manual/test
procedure and nol have 1o come back to reset the conkoller io AUTO.
NOTE: All manual^est p.ocedures ignore the sensor connection. Therefore, you can water
utilizing one of the manual/test procedures even iI lhe sensor has suspended your
scheduled program.
Run a Zone Manually
Turn the large dlal to ihe MANUAL posit on. The delau t ol zone 01 and 00:T 0 minutes wi I be

ADVANCED FEATURES
The SmartzonerM EZ incorporales Nelson's ManualAdvance-'r fealure in the MANUAL
procedure. ManualAdvancen allows you to cease the currently running zone and immediately
advance to any new zone you seJect. W th lhe MANUAL procedure running a zone, pTess
SELECT !: lo advance lo a new zone. The last enlered run time will be displayed- Press
ADJI,ST !: to enter a new run time lor the new zone (the controller w lt delay ] O seconds belore
