INSTALLATION INSTRUCTIONS

NOTE: Instructions are for indoor or outdoor use.

Find a location near a 110V (220V for 8574, 8576, 8578, and 8582 models) outlet or a 110V wiring source. Install the SmartZone™ EZ near eye level if possible. Open the face panel by loosening the panel locking screw and pulling the tab on the right of the front panel to swing the panel open on its hinges. Use the three holes in the case to mark and pre-drill pilot holes in the wall. The left two hole guides in the SmartZone™ EZ are vertically aligned for mounting the controller to a stud. (See Figure 1) Insert screws through the holes in the case and screw each into the corresponding pilot hole in the wall.

NOTE: The front panel can be removed to aid in installation by removing the ribbon connector from the interconnect board and pulling the front panel off its hinges.

INSTALLATION INSTRUCTIONS

Terminal Strip

All zone, pump and sensor wire connections made inside the SmartZone™ EZ utilize tool-less connectors. Press on the terminal strip lever with a pen or small screwdriver and insert the wire into the bottom. The terminal strips in the SmartZone™ EZ controller accept 12 AWG (4.8mm) wire or smaller.

Connecting Master Valve or Pump-Start Relay

The SmartZone™ EZ is equipped with a shared circuit to operate either a pump-start relay or a master valve. Connect one wire from the pump-start relay to COM (common) on terminal strip, the other to PMP/MV (pump/master valve) on the terminal strip. Refer to the pump-start relay manufacturer's instructions for specific installation details.

Wiring the Transformer*

*110 VAC in United States, Canada and Mexico; 220 VAC in Europe and Australia NOTE: Refer to and follow local codes if different from these instructions.

CAUTION:

Disconnect 110V (220V for 8574, 8576, 8578, and 8582 models) power source before wiring transformer. Complete all wiring and installation before connecting the transformer to power source. This will avoid accidental shorting which could damage the controller.

INSTALLATION INSTRUCTIONS

For models 8504, 8506, 8508, 8512

With front panel open to provide access to the internal transformer, bring 110V wires up through 1/2'' conduit hole in the bottom of the case. (For field connection, AC wires must have an insulation rated at 75^ minimum). Conduit should be secured to the case (follow local codes). Attach AC wires to transformer wires using wire nuts. Also, ensure earth ground wire is attached to green with yellow stripe ground wire. Please check local codes for the grounding requirements in your area. Bundle wire within cable tie loop and tighten cable tie to prevent loose wiring from touching secondary circuits. The transformer is now wired. DO NOT turn on power yet.

For models 8574, 8576, 8578, 8582

With front panel open to provide access to the internal transformer, bring 220V wires up through 1/2'' conduit into the left hole in the bottom of the case. (For field connection, AC wires must have an insulation rated at 75^ minimum). Conduit should be secured to the case (follow local codes). Connect AC wires to connector provided and tighten screws. Observe proper polarity of wires as you install them (ie. L1, L2 and ground). Bundle wire within tie loop and tighten cable tie to prevent loose wiring from touching secondary circuits. The transformer is now wired. DO NOT turn on power yet.

NOTE: Failure to ground unit properly may cause severe damage to the controller and/or personal property and will void warranty.

For models 8514, 8516, 8518, 8522:

The transformer has been pre-wired with a 6 foot AC power cord with grounding plug. We recommend that you do not alter this connection. Replacement of this cord must follow local codes and in all cases the unit must be properly grounded.

INSTALLATION INSTRUCTIONS

Connecting Rain/Moisture Sensor

The SmartZone™ EZ is equipped to operate a sensor with normally-closed leads. The sensor port on the SmartZone™ EZ is the first tool-less connector on the interconnect board (see Figure 2). To install a sensor, remove the factory-installed jumper wire from the sensor connector on the terminal strip and insert the sensor wires. Refer to the sensor manufacturer's instructions for specific installation details.

FIGURE 2

If a sensor has suspended watering, the sensor indicator segment will appear on the LCD. The symbol will go off when the sensor has dried out or when the controller is set in one of the manual modes (see pages 23-25). The SmartZone™ EZ will resume operation based on the selected program.

INSTALLATION INSTRUCTIONS

Connecting Battery and Resetting Controller

Connect one 9V Alkaline battery to the battery clip and insert into the battery holder on the back of the front panel. The battery enables the SmartZone™ EZ to be programmed without AC power and maintains the real time clock in the event of a power outage. If a battery is not installed, the controller will lose real time in the event of a power outage. The battery should be replaced once a year.

CAUTION: Use a 9V alkaline battery only. A 9V NiCad battery may leak or explode causing personal injury or property damage.

After installing the battery, press the black reset button on the back of the front panel to reset the controller (does not affect program(s)). To reset the controller to its default settings, press both the black reset button and the SELECT key simultaneously. Release reset button before releasing select key. Close the front panel, being sure not to damage wires. If wires are stiff, you may find it helpful to pre-bend them. Tighten the panel screw to secure the front panel to the case. Plug in the AC cord for the transformer or turn on the power 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.

You're now ready to start programming!

PROGRAMMING INSTRUCTIONS

Programming Overview

Before programming the SmartZone™ EZ, it may be helpful to become familiar with some general programming guidelines:

• If a segment(s) on the LCD is flashing, it means that it can be changed by the user.
• When using or keys, hold the button three seconds to start a fast scroll.
• Be sure the appropriate program letter is displayed when you are programming; program changes are specific to the program letter displayed on the LCD.
• There is no "ENTER" key. Key-presses and dial settings are stored automatically for you.
• If you make a programming change while a program is running, the program terminates immediately. The new program starts at the next start time scheduled.
• When not running, the controller displays the current time and the current day.
• During manual operations, there is a 10 second delay before the operation begins. During this time, you can change your settings. Each time you make a change, the delay resets to 10 seconds.
• MANUAL, CYCLE, and 3 MINUTE TEST procedures only operate with the Program dial set in the AUTO position.
• After a test procedure runs, the controller reverts back to the AUTO procedure and runs the next program scheduled.
• The test procedures ignore the sensor connection; this allows you to water or run your program even if the sensor has suspended operation.

PROGRAMMING INSTRUCTIONS

Front Panel Layout

Looking at the front panel (see figure 4), you see a large LCD, 4 rubber buttons, one large rotary dial, and two small rotary dials. The rubber buttons are marked "SELECT" and "ADJUST" and are the heart of Nelson's exclusive SELECT&ADJUST® programming. The keys are identified with for increasing or decreasing the segment you're working on.

SELECT&ADJUST works on the principle that you first SELECT what you want to set, and ADJUST the variables of what you selected. For example, if you want a run time of 10 minutes on zone 5, you would use the SELECT keys to select zone 5 and, once on zone 5, you would use the ADJUST keys to set the run time to 10 minutes.

There are instances when only SELECT or only ADJUST is required. They will be explained in this guide where appropriate. A Rule of Thumb: SELECT will select zones or a particular start time (1,2 or 3). ADJUST will adjust Times, Dates, and % Water Budget. See the hang card inside the lid of the SmartZone™ EZ for a quick reference on what buttons to use for different dial positions.

FIGURE 4

NOTE: The MODE dial must be in the "Program" position.

NOTE: Every time the or key is pressed, the time will increase or decrease one minute. Hold the or key for three seconds to initiate a fast scroll.

NOTE: Please refer to the Technical Data section for an explanation of the LCD segments

PROGRAMMING INSTRUCTIONS

Set Time of Day

Turn the large dial to the TIME position. Press ADJUST to scroll to the correct time. There is no A.M. indicator.

Set Current Day

Turn the large dial to the CURRENT DAY position. Press SELECT ± to position the current day indicator over the current day. SELECT ± will advance the indicator to the right;

SELECT will advance the indicator to the left.

Set Today's Date

Turn the large dial to the DATE position. Press ADJUST keys to scroll to the current date. The YEAR will automatically advance upon rolling over 12/31.

NOTE: A DATE is only required if you intend to use ODD/EVEN scheduling or to set a start date, other than the current date, for INTERVAL scheduling.

Select Zones and Set Their Run Times

A zone run time determines the duration a zone will run.

Turn the large dial to the ZONE / RUN TIME position. Press SELECT to select the zone you want for the selected program (A, B, or C). With the zone number displayed on the LCD, press ADJUST to adjust the RUN TIME for that zone. RUN TIMES can be set from 1 minute to 9 hours 59 minutes. Continue selecting zones and adjusting their run times until you have all the zones you want in the selected program.

PROGRAMMING INSTRUCTIONS

After the last zone and before the first zone, a RUN TIME summation is provided. This is useful for determining the total run time for a program. The LCD displays the letters "ALL" and a total RUN TIME is displayed. The time displayed is a summation of all the RUN TIMES for the selected program (100% water budget). (ex. A program has a run time of 5 minutes on zone 1; 12 minutes on zone 2; and 6 minutes on zone 4. The display at this position displays ALL and a run time of 23 minutes).

FIGURE 5

PROGRAMMING INSTRUCTIONS

Set Start Times

A START TIME is the time of day a program will start running. The SmartZone™ EZ allows three start times per program.

Turn the large dial to the START TIMES position. Press SELECT to select the start time you want to set (1, 2, or 3). Press ADJUST to set the time of day the program will start. Repeat as needed.

Set % Water Budget

% WATER BUDGET changes the duration of run times in a program by the percentage entered 5 - 200% (i.e., a 10 minute run time at 50% water budget will run 5 minutes). This feature is useful when changes in weather occur. If it is unusually dry, you may want to extend your run time for each zone in a program. With % Water Budget, you can change one number, and all run times in the program are adjusted.

Turn the large dial to the % WATER BUDGET position. A % symbol will appear on the LCD to let you know you are working on the % Water Budget amount. Press ADJUST to choose the desired percentage amount.

PROGRAMMING INSTRUCTIONS

If water budget is set for 110% or greater, the SmartZone™ EZ will split the run time in half to reduce runoff. Half of the calculated run time will operate for each zone in that program, followed by the second half of the run time for each zone.

Remember, % Water Budget is changeable by program. If you have programming in A, B, and C, you must enter three water budget values if you want every program to be changed.

SCHEDULING

A quick note on scheduling and the SmartZone™ EZ ...

The SmartZone™ EZ controller has three scheduling options:

• WATER DAYS, or daily, lets you choose which days of the week you want to water (i.e., Monday, Wednesday, Friday only).
• ODD/EVEN tells the controller to water on either the odd or even days of the month (i.e., the controller will water on the 31^st and the 1^st when an ODD schedule is chosen).
• INTERVAL waters every X number of days (from 1 to 30 days) (i.e., water every 3 days, water every 10 days, etc.). A value of 1 in an interval schedule means to water every day. When using the interval option, you have the flexibility to tell the controller what day to start the interval program on (up to 30 days out).

PROGRAMMING INSTRUCTIONS

NOTE: The MODE dial must be in the "Program" position to set a schedule.

When the dial is set to any of the scheduling options, the LCD will display the currently scheduled program (default is a 1 day interval schedule with today's date for a start date). Be sure the PROGRAM dial is set on the program you want to change (A, B, or C) and that you want to change the current schedule. A scheduling option is chosen after you press a button, either SELECT or ADJUST. The old schedule is replaced with the new one. If you want the old schedule back, it's easy to reprogram with the following procedures.

Set Water Days Scheduling Option

Turn the large dial to the WATER DAYS scheduling option. The last scheduling option chosen for the current program or the default 1 day interval scheduling option will appear on the LCD. Press the SELECT button to select that day for watering or press SELECT for non-watering days.

A flashing indicator appears over the day you're about to set. Rain drops appear over selected days to water. The indicator automatically moves one day to the right after a SELECT or key press. Continue selecting or deselecting the days you want the controller to water until you have your 7 day calendar set.

NOTE: Programming a WATER DAYS schedule deletes any other schedule for the selected program.

PROGRAMMING INSTRUCTIONS

Set Odd/Even Day Scheduling Option

Turn the large dial to the ODD/EVEN position. The last scheduling option chosen for the current program or the default 1 day interval scheduling option will appear on the LCD. To set either an odd or an even schedule press the SELECT button (a date must be set for odd/even watering). An arrow will appear on the LCD next to the appropriate schedule (Odd or Even). The SELECT buttons act as toggle keys and will toggle between odd or even.

NOTE: Programming an ODD/EVEN schedule deletes any other schedule for the selected program.

Set Interval Scheduling Option

Turn the large dial to the INTERVAL position. The last scheduling option chosen for the current program or the default 1 day interval scheduling option appears on the LCD. Press SELECT to set the interval days between watering (1-30). The date displayed is day one of the interval schedule. (today's date if one has been set). As needed, change the date for day one of the interval schedule with ADJUST (can only be set up to 30 days out).

Repeat the above procedures for each program (A, B, or C) you require.

That's it! Your SmartZone™ EZ is now programmed. Turn the MODE dial to the AUTO position to run the program you entered.

NOTE: Programming an ODD/EVEN schedule deletes any other schedule for the selected program.

PROGRAMMING INSTRUCTIONS

PROGRAM REVIEW

To review the current program, Turn the MODE dial to the PROGRAM position and turn the large dial to the setting you wish to review (i.e., turn the large dial to TIME to review the time set for the controller). When you need to view different zones or run times (1, 2, 3), use the SELECT + button only.

NOTE: Since you are in the program mode, the potential exists to change the program accidentally.

There are instances when you'll want to suspend watering, either for short periods (while it's raining if you don't have a sensor connected), or long periods (during winter). To accommodate this, the SmartZone™ EZ can be turned "Off". Turn the MODE dial to the OFF position. This suspends all watering operations (including manual/test procedures) from operating. The clock continues to maintain the current time and date and your program(s) is retained until you want to run your program(s) again. To run your program, turn the MODE dial back to the AUTO position.

NOTE: The non-volatile memory of the SmartZone™ EZ will maintain your program without power. If a battery is not present and AC power is lost, the real time for the clock will be lost. The time will need to be reprogrammed.

ADVANCED FEATURES

The SmartZone™ EZ incorporates three manual/test procedures for checking the function of the controller or allowing you to bypass the current program to water immediately. The following section will show you how to set up the controller to:

run a zone manually
run a program manually
- run a 3 minute test of every programmed zone

NOTE: All test procedures are run with the MODE dial in the AUTO position. This allows the controller to reset to the AUTO setting after running a manual/test procedure. It also allows you the ability to walk away from the controller after setting up a manual/test procedure and not have to come back to reset the controller to AUTO.

NOTE: All manual/test procedures ignore the sensor connection. Therefore, you can water utilizing one of the manual/test procedures even if the sensor has suspended your scheduled program.

Run a Zone Manually

Turn the large dial to the MANUAL position. The default of zone 01 and 00:10 minutes will be flashing (recall that this means you can change them). Press SELECT to select the zone number that you want to run. Press ADJUST to set the run time for the selected zone. The controller will delay 10 seconds before starting the zone.

ADVANCED FEATURES

The SmartZone™ EZ incorporates Nelson's ManualAdvance feature in the MANUAL procedure. ManualAdvance allows you to cease the currently running zone and immediately advance to any new zone you select. With the MANUAL procedure running a zone, press SELECT to advance to a new zone. The last entered run time will be displayed. Press ADJUST to enter a new run time for the new zone (the controller will delay 10 seconds before starting the new zone).

Run a Program Manually

Turn the large dial to the CYCLE position. The current program letter will flash. To change to a different program, turn the PROGRAM dial to the desired program (A, B, or C). The controller will delay 10 seconds before starting the selected program. After running, the controller resets to the AUTO procedure.

NOTE: CYCLE runs your current program immediately. Changes cannot be made to the program in the CYCLE procedure.

Run a 3 Minute Test (Syringe)

Turn the large dial to the 3 MINUTE TEST position. A B C will flash on the LCD (they cannot be changed). This is to let you know the controller will review all three programs and run a 3 minute test on only those zones that have been programmed. We call this SmartSyringe!.

This feature allows the controller to skip zones that have not been programmed. These may be zones that are not hooked-up, hence, saving your pump (if equipped).
