SmartLine Owner’s Manual


1.0 Getting Acquainted With Your SmartLine® Controller

SmartLine® is the smart choice for water conservation and beautiful landscaping. The “get acquainted” information in this section will make programming your unit easier and faster.

1.1 Getting Acquainted With Your Control Panel

The SmartLine® Controller LCD Display provides the following information when the controller is set to RUN, SYSTEM OFF, or when there is no active watering operation underway (display with program in IDLE mode):

Time of Day: SmartLine® Controllers use a Real Time Clock/Calendar instead of a backup battery to maintain correct time during a power outage. For the SL1600 and SL4800, the display will show a blank battery icon in the display, this is used for viewing the RFS5 and SLW5 when testing the battery levels from the ADVANCED MENU of the control panel.

Next Watering Day or Days: The display will show the watering days in the current week for Program A. To view watering days for Program B, C or D just press the PGM button. 

Fault Indicator: Appears ONLY when a fault is detected. Turn dial to Advanced Menu and press the DOWN then NEXT button to view faults. Once you turn the dial to Advanced Menu the fault indicator will stop flashing but will continue to appear on the screen until the fault is removed or user clears fault in Advanced Menu. If fault is cleared in Advanced Menu, it will appear again the next time the program runs if the problem is not corrected.

PGM Button:

The SmartLine® controller has 4 watering programs (A, B, C, and D). This is like having 4 controllers in one. You can assign zones to any of the 4 programs, allowing for complete flexibility of your irrigation schedule. Programs A, B, C, and D can be programmed to operate concurrently. The display will alternately show all active running programs when in use. Sprinkler zones should be assigned to Programs A, B and C as Program D is intended for micro irrigation with low flow and long run times. Sprinkler zones should be assigned to A, B, or C. 

Care must be taken when programming. In order to not exceed your irrigation system’s hydraulic capacity, double check the strength of your piping and points of connection. Exceeding this capacity could lead to fault indications and interrupted irrigation schedules. The electrical capacity is limited, depending on your model. A pump start relay may require more mA than a solenoid. Keep aware of these boundaries when scheduling programs to initiate and operate simultaneously.

START MANUAL PROGRAM Button: Press to initiate a watering operation when the programming dial is set to the RUN position. The SmartLine® controller will run Program A. Or, you can push the PGM button before you push the START MANUAL PROGRAM button to select the program you want to run. You can use the NEXT button to advance to other zones in a program that you have started. Start Manual Program will override any omits or delays.

Display With Program Running: When a program is running, the screen will display: program that is operating; zone number that is operating; and run time remaining. An ORANGE LED indicates program is in PAUSE mode waiting for a programmed delay in the controller to expire (run/soak, master valve delay, zone to zone delay, omit time). The display will show the reason for the pause. 

Display With Dial In SYSTEM OFF Position: When the SmartLine® controller dial is in the SYSTEM OFF position, the processor and clock continue to operate and all program values are retained in the non-volatile memory. In the SYSTEM OFF position no automatic watering will occur. The Mode Selection LED will display red when controller is turned to SYSTEM OFF.

If you move the dial to any position other than RUN or SYSTEM OFF, and there is no control panel activity for 1 hour, the controller will return to the RUN mode, and the display screen will show the idle default screen or will return to a program in progress that was interrupted.

Watering Mode Button: Used to select SMART or BASIC watering. During normal operation the MODE LED will display GREEN. It will change to ORANGE during a pause in operation and will display RED when SmartLine® controller dial is turned to SYSTEM OFF.

Rain/Freeze Sensing Button: Used to activate or bypass optional sensors for rain, freeze, or wind. If these sensors are connected to your SmartLine® controller, they will override watering operations if the ON LED is selected. If your sensor/s have paused your system operation, the ON LED will be RED until the sensors allow watering to resume. In the event of a “rain” pause, the LED will change from RED to ORANGE for an additional pause time before the LED displays GREEN and system operation resumes. Smart Watering deficits will decrement to 0 at the rate of 1″ per hour. The sensor LED will display GREEN again when the sensor/s are no longer pausing your system operation.

Note: No watering will take place when the RAIN/FREEZE SENSING LED is RED. This indicates a Rain, Freeze or other type sensor has tripped, and programs are prevented from running. An ORANGE MODE LED means watering is paused temporarily due to: run/soak, master valve delay, zone to zone delay, or omit time. A program in operation will also pause if you turn the dial to any position other than RUN or SYSTEM OFF. The program in operation will resume when you return the dial to RUN or if there is no programming activity for 60 minutes.
Note: The SLW Delay dryout period is factory set for 48 hours. To change the delay period, see SLW in Advanced Menu. 

If you wish to deactivate the sensors, use the RAIN/ FREEZE SENSING button to light the green OFF LED. Example: You wish to water after fertilizing and your rain sensor is still pausing the watering program. As long as the OFF LED is on, the sensors will not pause your system operation. Note: You may have zones you want to omit from rain/freeze shutdown. Example: Potted plants under cover. If you are using an SLW Weather Sensor or the RFS5 rain/freeze sensor communicating with your controller through an SLHUB, see SLW in Advanced Menu for instructions. If you are using a rain/freeze sensor connected to your controller at the SEN terminals, see SENSOR in Advanced Menu for instructions.

 Note: The RAIN/FREEZE SENSING button can be used to bypass rain and freeze sensors.

1.2 Quick-View

With the dial in the RUN or OFF position and FLOW is enabled through SmartLink Network, press the down button once to reveal REAL-TIME FLOW. It will display the current flow rate from active running zone valve(s) or mainline activities such as Quick Coupler Valves or Hose Bibs through the LEAK DETECT function.

2.0 Programming the Controller

Your SmartLine® controller has two operating modes: BASIC mode or Weathermatic’s patented SMART mode. The BASIC mode uses user assigned zone run times. The SMART mode overrides user assigned zone run times and calculates zone run times based on the location of the site, inputs by zone, and weather readings from the SLW Weather Sensor. Note: SMART requires the optional SLW Weather Sensor. 

Smart watering calculates ET (evapotranspiration), the landscape’s daily water loss, and schedules the correct amount of irrigation to replace the loss. When combined with a Weathermatic SLW Weather Sensor, Smart mode gives you the power to reduce water waste. Many water districts are offering rebates for Smart mode users. Check with your local district.

Both the BASIC mode and SMART mode operate based on the user’s programmed start times, watering days, omit times/days, and several Advanced Menu features (rain delay, zone to zone delay, and master valve settings).

Important Note: Zone run times must be entered for every zone in use for the controller to recognize the zone in either BASIC or SMART modes.

2.1 Using the Programming Buttons

A FLASHING DISPLAY indicates that user choices are available. The UP and DOWN Adjust Value buttons are used to scroll through numeric values or to make a choice of menu options. 

NEXT and BACK Buttons: When watering zones are being programmed, the left side of the display will indicate the zone number. The NEXT and BACK buttons are used to scroll through the zones. If the flashing display indicates a menu selection rather than a numeric value, the NEXT button will open the menu for further programming. The BACK button will exit the menu and cause the chosen value to be saved in memory.

RAPID ADVANCE: While programming, holding down the UP or DOWN button will cause the flashing display value to rapidly advance. Rapid advance can also be used with the NEXT and BACK buttons to rapidly advance through zones.

MENUS WITHIN MENUS: In cases where there are menus within menus, each press of the BACK button will return to the next higher menu until the top level menu of the dial position is reached.

A VALUE CHANGE: Saves after 30 sec of inactivity or dial position changed to RUN or OFF.

2.2 Current Time/Date

Use UP and DOWN buttons to change the flashing value for the hour. Scrolling past 12 will automatically change AM/PM. Remember holding down the UP or DOWN button will rapidly advance through the flashing menu.

Use NEXT button to flash minutes. Use UP and DOWN buttons to set minutes. Push NEXT to access calendar setting. Use UP and DOWN buttons to set month/day/year. (Note: For international users, the display will read day/month/year.) Your SmartLine® controller has a 100-year calendar, so when you have entered the correct date, the SmartLine® controller will automatically display the correct day of the week. Your SmartLine® controller will automatically adjust for leap years and USA daylight savings time. See DS TIME, in Advanced Menu to to turn the feature on/off and change the DST schedule.

2.3 Program Start Times

Set Start Time for each program to be used (A, B, C and D). If more than three program start times are desired, refer to NUM STRT, in Advanced Menu. The program will start at the time you designate and will water all zones with set Zone Run Times for that program.

For most watering programs set only Start Time #1. The #1 Time will water all zones with Zone Run Times set in that program in consecutive order. Extra start times will re-run all zones. Extra start times may be used for new planting grow-in or other special local conditions. Unused start times must be set in the OFF position. To set a start time at OFF, press on either UP or DOWN button until you reach the OFF position located between 11:50 PM and Midnight.

When setting program start times, check the program icon in the display to see whether you are working in A, B, C or D. Use PGM button to move between programs. Use NEXT and BACK buttons to move between start times. Use UP and DOWN buttons to set each start time desired. Start times are selectable
in 10-minute increments.

Push PGM button to assign zone time in one or more programs. Care has to be taken when programming. You need to have awareness of the hydraulic capacity of the irrigation system piping and points of connection so that they are not exceeded. Further care should be taken so the electrical capacity of the controller is not exceeded. The electrical capacity is 750 mA or 3 irrigation solenoids. A pump start relay may require more mA than a solenoid. Keep aware of these boundaries when scheduling stations to initiate and operate simultaneously.

Note: Be sure you select the AM/PM time as desired by scrolling past 12. (For international users, the display will show international hours instead of AM/PM.)

2.4 Zone Run Times

Your SmartLine® controller will display remaining hours, minutes and seconds when a zone is watering. However, in this position you are only required to set minutes (or hours and minutes) for each zone as desired for operation time. Seconds are not selectable. 

Use NEXT and BACK buttons to select zone for run time setting. All zones are selectable from 1 minute to 9 hours and 55 minutes. Run times of OFF to 59 minutes are selectable in one minute increments. Run times of 1 hour to 9 hours 55 minutes are selectable in 5-minute increments. Use UP or DOWN buttons to set flashing time values for each zone. If a zone is not to be used, set it to OFF. Caution: If an unused zone is turned on and activates a pump start relay, the pump may overheat or cause a pipe to burst. To prevent operating a pump with no flow (dead heading), make sure all unused zones are set to OFF.

 Note: Run/Soak feature can reduce the need to set multiple start times for the purpose of preventing runoff. Using the combination of multiple start times and Run/Soak cycles can lead to extended watering windows since Run/Soak cycles are applied to each start time. See Soil Type, page 9 section 4.2.3.

2.5 Days to Water

In this dial position you can select DAYS, EVEN, ODD and INTERVAL watering schedules. Use UP and DOWN buttons to select which type of schedule you want in your SmartLine® controller. Remember to check the Program (PGM) selection showing in the display. You can select a different watering schedule for each program if you wish.

If you select DAYS, then use the NEXT button to step through each day of the week and the UP and DOWN buttons to select ON or OFF status for each day. Days selected to water will be displayed at the top of the display.

If you select an INTERVAL schedule, push NEXT button. The flashing number indicates the day interval for watering. SmartLine® controller will allow an interval of 1 (every day) to 30 (water once every 30 days). After you have selected the interval you want, push NEXT to set the day you want the interval schedule to start on. Use UP and DOWN buttons to select start day at top of display. The controller will begin on the next upcoming start day.

Note: The display will only show the upcoming watering days for the current week.

To select EVEN or ODD watering days, simply press the UP or the DOWN button when viewing the panel option DAYS TO WATER. If ODD is flashing on the display when you turn the dial to another position, you have selected ODD. The same is true for EVEN. When you return the dial to RUN, you can view the next day that your schedule will run. The SmartLine® Controller will run ODD or EVEN programming at the next available start time, even if it is on the same day that you set up the schedule. If you are using an ODD schedule, the SmartLine® controller will not water on the 31st day of a month and February 29th of a leap year to prevent two consecutive watering days (31st and 1st or 29th and 1st).

2.6 Omit Times/Days/Dates (Optional)

The omit settings are used to set a watering blackout period. For example, if you live in a municipality that restricts outdoor watering between 10:00 am and 6:00 pm, you can blackout that time period. If a watering program in progress is paused for a blackout period, the ORANGE LED will display during the pause. The watering cycle will automatically resume at the end of the blackout period. Use the UP and DOWN buttons to select OMIT:TIME, OMIT:DAYS, and OMIT:DATES. You may choose any or all of these omit options.

If you want a watering blackout for the same period each day, select OMIT:TIME. Then push NEXT. A forward (>) arrow indicates the beginning time for the blackout. Use UP and DOWN buttons to set beginning time. Then push NEXT. A reverse arrow (<) indicates the end time for the blackout. Use UP and DOWN buttons to set ending time. The OMIT:TIME function will pause any active watering program until the blackout period has expired.

If you want to omit a specific day or days each week from watering schedules, select OMIT:DAYS with the UP and DOWN buttons. Then push NEXT. Display will show a day of the week with Omit or Allow flashing. Use UP and DOWN buttons to select Omit or Allow. Use NEXT or BACK to scroll between days of the week. Omitted days will be visible at the top of the display. Any running user program will be stopped at midnight in order to honor omit days or dates. Programs scheduled to start on an omit day will be skipped.

If you want to omit specific dates during the year, select OMIT: DATES. Then push NEXT. Enter the month and date. Push NEXT to enter up to 15 dates. Scrolling the month value between 12 and 1 causes mm/dd to appear and clears the omitted date/s. Any running user program will be stopped at midnight in order
to honor omit days or dates.

2.7 Monthly % Adjust (Optional)

The Monthly % Adjust feature allows the user to modify zone run times by program for each month to easily adjust watering for seasonal climate changes. The time programmed for each zone in ZONE RUN TIMES is always the value for the 100% setting in Monthly % Adjust. When you use the Monthly % Adjust, you are increasing or decreasing the 100% time value. % settings in this mode are 0 to 300% in 5% increments. Use UP and DOWN buttons to select % desired. Press PGM to choose program. A 0% setting will adjust zones to a zero second runtime.


 Note: When the SmartLine® controller is in SMART mode this feature is voided. SMART mode will change zone watering times daily.

3.0 Manual Start Functions

The SmartLine® controller has two dial positions for manual system starts:

3.1 Manual Zone

Manual Zone allows user to water a single zone for specified period of time. Use NEXT and BACK buttons to select zone. Use UP and DOWN to select run time for the zone. A zone can be operated with the Manual Zone function regardless of whether the zone has an assigned run time. You must return dial to RUN for Manual Zone operation to begin. All manual watering operations will override watering day settings, omit settings, and rain/freeze events.

3.2 Manual Test

The Manual Test can be used to set a test run time for all zones which have an assigned zone run time in any program. Any zone without an assigned zone run time will NOT run in the Manual Test. Use UP and DOWN buttons to set Manual Test run time. The Manual Test can be set to run a minimum of 10 seconds or a maximum of 10 minutes. You must return dial to RUN for Manual Test operation to begin.

Manual Test will detect open circuits (less than 30 mA draw) on any used zone or a short on any output (master valve or zone). If the display indicates FAULT while running a Manual Test, refer to Advanced Menu to identify the FAULT.

4.0 Programming for Smart Watering Mode

Weathermatic’s patented SMART mode overrides user-assigned zone run times and calculates zone run times based on the location of the site, inputs by zone, and weather readings from the SLW Series On-Site Weather Sensor. SMART mode is designed to help you protect your landscaping, reduce wasteful run-off, and minimize your water costs.

Warning: Smart mode positions on the dial can only be selected when an optional SLW Series On-Site Weather Sensor accessory is installed. Additionally, Basic Program Function must be set up completely before setting up SMART mode. SMART Mode replaces the Zone Run Times with a calculated value using the SMART settings.

4.1 Set ZIP Code or Latitude

SMART operation first requires that the SmartLine® Controller know “where in the world” it is located. Users in the USA can set location by ZIP Code. Users outside of the USA can set location by latitude. Use UP and DOWN buttons to select ZIP Code (USA) or LATITUDE. To find your latitude, see World Latitudes in the Reference section.

If you are setting a ZIP Code, push NEXT. Display will show 5 numerical positions for ZIP Code settings. Use UP and DOWN buttons to set the flashing number. Then push NEXT to flash the next number. Use UP and DOWN buttons to set second number. Continue process until all 5 numbers of your ZIP Code are set.

If you are outside the USA, you will enter LATITUDE. You can use the UP and DOWN buttons to choose any latitude between 60 degrees south and 60 degrees north. 0 degrees setting is marked as EQUATOR.

4.2 Enter Smart Data for Zones

Enter SMART data for zones: Sprinkler Type, Plant Type, Soil Type, and MORE/LESS. The SmartLine® controller cannot calculate run times without SMART data for each zone and without Zone Run Times assigned to each operational zone, which serve to back up SMART mode.

4.2.1 Sprinkler Type

In order to calculate run time, the controller must know the expected precipitation rate for each zone. Use NEXT and BACK buttons to move between zones. Use UP and DOWN buttons to set zone to OFF or to
specify the precipitation rate.

Precipitation rate can be entered two ways: by sprinkler type or by specific precipitation rate. If you do not know the specific precipitation rate for the zone, you can select the sprinkler type, or watering equipment used on that zone: Spray, Rotor, Drip, or Bubbler irrigation. The SmartLine® controller will apply a default precipitation rate for the sprinkler type selected. If you know the specific precipitation rate expected for the zone, stated by the sprinkler manufacturer, you can use the UP and DOWN buttons to scroll past the sprinkler types and select that number. For USA users, inches per hour will be displayed (.2 to 3.0 inches per hour). Numeric precipitation rate resolution is 0.01 in/hr below the 2.0 in/hr setting. For international users, the controller will display precipitation numbers in centimeters per hour. As a rule in SMART mode, the lower the precipitation rate entered, the longer the zone run time will be to achieve required plant life needs. For zones selected to use set Zone Run Times rather than SMART run times, select BASIC setting Sprinkler Type. Program features and operations are supported with BASIC zones, including Run/Soak, and BASIC zones may run within SMART programs or separately.

4.2.2 Plant Type for Zones

This position is used to specify the type of plant material to be watered by each zone as an important component of determining the watering needs for each zone. Use the UP and DOWN buttons to select plant type or percent for each zone. Press NEXT and BACK buttons to access each zone. 

Plant type selections are: CTurf (cool turf like bluegrass); WTurf (warm turf like St. Augustine); Shrubs; Annuals (floral beds); Trees; and Native plants. The SmartLine® controller formula uses cool turf mowed at 4 to 6 inches tall as the base watering number (100%) or crop factor. The cool turf default is 80% considering average mowing heights of 2 to 3 inches, which result in less transpiration and lower water requirements. If you prefer more specific input, you can scroll past the plant types and use % designations of 10 to 300%. For
example, a Native plant zone might be assigned 30% rather the default of 25%. As a rule in SMART mode, the higher the plant type percentage entered, the longer the zone run time will be to achieve required plant life needs.

For maximum water savings, it is recommended that your sprinkler system be zoned with a separate valve for each type of plant material. If you have mixed types of plants in a single zone, you will need to select which type of plant to use in the determination of water requirements.

4.2.3 Soil Type for Zones

Soil settings for soil type and degree of slope are used to enable your SmartLine® controller to automatically calculate the maximum length of a zone run time before pausing watering for a calculated period to allow the water to soak into the soil. These Run/Soak (also called Cycle/Soak) periods based on industry BASIC formulas reduce wasteful runoff caused by watering more than the soil can absorb. The Run/Soak feature included in Advanced Menu can be manually entered for use with the BASIC mode. However, in the SMART mode, the SmartLine® controller will automatically calculate Run/Soak times with soil inputs made at the soil type position on the dial. Run/Soak settings made in Advanced Menu are not active when controller is in SMART soak schedules can be viewed by selecting Advanced Menu, Review and Run/Soak.

Use the UP and DOWN buttons to select Clay, Loam or Sandy soil type for each zone. After you have selected a soil type for a zone, push NEXT button to advance to the next zone. Slope for each zone can also be set in the Soil Type menu. From the Soil Type menu, use the UP and DOWN buttons to select Slope. Using the NEXT button select the degrees of slope (elevation change) for each zone. Set each zone for 0 to 25 degrees of slope based on the chart provided. 

Use NEXT button to move between zones.

 Note: Factory default settings are clay soil and zero slope.

4.2.4 More/Less (optional)

 Note: Run/Soak period can reduce the need to set multiple start times for purpose of preventing runoff. Using the combination of multiple start times and Run/Soak cycles can lead to extended watering windows since Run/Soak cycles are applied to each start time.

When your SmartLine® controller is set in SMART mode, the Seasonal % Adjust in the BASIC mode is inactivated since the automatic adjustments are made daily rather than monthly. You can use MORE/LESS to fine tune the run time calculation by zone in the SmartLine® controller by –50 to +25%. 

Use UP and DOWN buttons to select % adjustment. Use NEXT and BACK buttons to move between zones.

This feature can be useful to reduce run time adjustments for shady and partially shaded zones. The table provided may be used for general shade guidelines. Other factors may result in needing to use MORE/LESS for fine tune adjustments including sprinkler efficiency, zone efficiency, and wind. Sprinkler efficiency varies between types of sprinklers and the manufacturer’s design. Zone efficiency varies based on the design layout of sprinklers in a zone, sometimes overlapping or sometimes not. High winds can
serve to dry out plant and soil to increase the need for water. For optimum results considering the many unique variables in each zone, users should periodically monitor plant life health and water usage, especially after initial controller setup, so proper adjustments can be made.


4.2.5 Activating the SLW Series On-Site Weather Sensor

SLW5 wireless and SLW1 wired weather stations both communicate with the controller via an SLHUB transceiver. Install the SLHUB by inserting the pins of the HUB into the connector located at the top right of the controller cabinet. On the SLW Weather Sensor, press and hold down the Rain Sense test tab in the center of the rain sensor for 15 seconds.

4.2.6 WATERING MODE Button

Press the WATERING MODE button on the control panel to place the SmartLine® controller in the SMART mode. A GREEN LED on the SMART position will confirm that you have communicated with the SLW Weather Sensor. If there is no SLW Weather Sensor installed or ZIP Code or Latitude or time/date setting and at least one zone with a sprinkler type set, pressing the WATERING MODE button will flash the SMART LED to RED and then return to the BASIC mode. When this occurs, you can press the MODE button to see a scrolling message indicating the reason SMART mode is not available.

5.0 Advanced Menu

Advanced Menu provides additional information and allows more technical inputs commonly used by professional installers. Advanced Menu contains menus within menus. To advance to a sub-menu, press the NEXT button. Each press of the BACK button will return you to a higher level until the top level of the Advanced Menu dial position is reached.

Refer to the chart below for the location of features within the menus.


Your SmartLine® controller can assist you with several diagnostic functions by pressing NEXT when TESTS appears.


Use the UP to select OUTPUTS function. Then use NEXT and BACK buttons to scroll through MV and Zone Valves to view AC Amp reading for each valve. Scroll BACK to OUTPUTS display to move to next diagnostic function. Typical range is .15 to .35 Amps per valve with a valve connected. An OPEN or SHORT message indicates a problem with a zone. Note: If you have more than one valve on a zone, the SmartLine® controller will measure total current for the combined valves.

5.1.3 24V PWR

Use the UP button to select 24V PWR. Push Next button once to read output voltage for the transformer. Normal reading is 24 to 30 volts AC.


This feature will create a “chatter” for a selected valve as a convenient method of locating buried valves. Use NEXT button to scroll to the valve you want to “chatter.”

Note: In order for the locator feature to work, you will need to turn off the system water pressure at the manual cut-off valve or water meter. Pressure must be off while attempting to “chatter” a valve. The SmartLine® controller will automatically sequence "chatter" to each valve including the master valve(s).


This feature is used to identify problems that may require attention or repair to insure proper operation of the system. Use NEXT button to view the type of fault. If more than one fault exists, you can use the UP and DOWN buttons to search for additional faults. Use the NEXT button to view the type of fault. If more than one fault exists, you can use the UP and DOWN buttons to search for additional faults. Use the NEXT button on the fault description currently displayed and the screen will read CLEAR, press the NEXT button to CLEAR the fault and the fault icon on the display will disappear. However, if the cause of the fault is not corrected, the controller will continue to skip watering a zone with a fault and will resume the flashing FAULT icon on the display each time that zone is operated. If additional faults are present repeat the procedure to remove them from the panel. Once the faults have been cleared the screen will read, no faults present. However, if the cause of the fault is not corrected, the controller will continue to skip watering a zone with a fault and will resume the flashing FAULT icon on the display each time that zone is operated.


This is a user selectable feature that sends a fault message for zones that detect no electrical load. From the ADVANCED MENU dial position press the UP button until the “OPEN FLT” menu is displayed. Press the NEXT button to enter the menu and the UP or DOWN buttons to select on or off for the alert.


English, Espanol (Spanish), Italiano (Italian), Portuguese, or Francais (French) may be selected.


This setting allows for you to choose either STANDARD (United States customary units) or METRIC. Press the BACK button when the display reads your desired selection.

5.13 NC/NO MV

Enter this menu to select between normally open or normally closed master valves for MV1 and MV2. Check with your valve manufacturer on the Model that has been installed to ensure the correct selection has been made. Maybe we should define the MV Types as; Normally Closed Master Valve requires the controller to send a 24VAC signal to activate the solenoid and open the valve to deliver water downstream to the zone valves. A Normally Open Master Valve will remain open at all times on the system without requiring a 24VAC signal to allow access to water in the mainline for Quick Coupler Valves or Hose Bibs connected throughout the system.

5.14 MV/ZONE

This feature allows you to select which master valve(s) to be assigned for each zone operation. The default is MV1. The other options are MV2, BOTH, OFF.
Caution: If an unused zone is turned on and activates a pump start relay, the pump may overheat or cause a pipe to burst. To prevent operating a pump with no flow (dead heading), make sure all unused zones are set to OFF.

5.15 MV/ZN DLY

This function allows the user to set a delay time between the opening of the master valve and the opening of the first zone valve as well as a delay between the closing of the last zone valve and the closing of the master valve.

Use the NEXT button to enter menu. Select setting for the ON Delay or OFF Delay by pressing NEXT. Use UP and DOWN buttons to select delay time. Use UP and DOWN buttons to set ON Delay time from 0 seconds to 1 minute in 1 second increments. OFF Delay can be set from 0 seconds to 3 minutes in 1 second increments.

5.27.3 NEXT RUNNEXT RUN is the total amount of run time SMART has calculated for each zone based on ET deficits and SMART system audit information entered on the SMART side of the dial. NEXT RUN is calculated and revised each night at midnight 365 days per year. The cumulative run time will carry forward until the next scheduled watering cycle. NEXT RUN times will return to zero after each watering cycle. To review NEXT RUN, turn the dial to Advanced Menu. Use the UP arrow button to access Review and then use the NEXT and BACK buttons to scroll through the zones.
5.27.4 RUN/SOAKThis feature allows the user to review expected Run/Soak schedules that will occur when the controller is in the SMART mode. Turn the dial to Advanced Menu. Use the UP button to go to REVIEW and press the NEXT button. Use the UP button to advance to RUN/SOAK. Press the NEXT button and zone 01 will show in the display. Press NEXT again and RUN with a time will show. This is the maximum RUN time the controller can do in SMART before going to SOAK. Press NEXT again and SOAK will show in the display with a time. This is the minimum time the zone must soak before it is ready to run again. SMART Run/Soak times can be changed by adjusting the soil and slope settings at SOIL TYPE on the programming dial. The times are also affected by adjusting the SPRINKLER TYPE setting on the dial for precipitation rate.
5.27.5 DEFICITDeficit is the amount of water (displayed in inches) that needs to be replaced for your plant material due to water loss through evapotranspiration – evaporation from soil and transpiration from plants. Your SmartLine® controller will calculate the water deficit each day at midnight based on data communicated to it by the SLW series Weather Sensor. The water deficit will continue to accumulate until the next scheduled watering cycle and will return to a zero reading when watering is finished. The SmartLine® controller uses an internationally recognized formula called the Hargreaves formula for calculating evapotranspiration.

During a rain event, deficits will decrease to zero. SmartLine® will not begin calculating deficits and run times again until the ACTIVE LED goes back to green after the SLW DLY.

If you wish to change the deficit numbers, press and hold down either the UP or DOWN button for 5 seconds. This allows you to use the DOWN button to reduce the latest deficit for the zone to as low as 0 inches.
