ISA timers provide simple programming and flexible watering schedules to meet almost any landscape’s needs. These timers can be used with any 110 VAC / 60 Hz electrical outlet (240 VAC / 50 Hz for the international version). This manual describes how to install, program, and operate your timer. Read this manual carefully and keep it in a handy place for future reference. If you have any problems with your ISA Sprinkler Timer, please call the Rain Bird Technical Assistance hotline at 800-247-3782 before returning your timer for service. You may also be able to find information to help solve your problem on the Rain Bird web site: www.rainbird.com. ISA Series Sprinkler T imer Timer ISA Timer Features and Benefits The ISA Sprinkler Timer is an electronic clock that controls when your sprinkler system turns on and how long the sprinklers run. The ISA timers offer several advanced features, including: • Large LCD display and easy-to-use programming dial and buttons • Six convenient pre-set watering schedules • Two independent watering programs (ISA 400 models) • Up to three watering start times per program • Ability to control four, six, or eight watering stations (depending on model) • Rain-Off feature can suspend watering and retain all programmed information Page 1 English Timer Stations Most sprinkler systems divide the yard into “stations” (also called “zones”). You can program each station to water for a different length of time, so the amount of water fits the different plant types, soil conditions, and sunny/shady areas in the yard. Each station has an irrigation valve that runs several sprinklers. An electric signal from the timer opens Page 2 the first valve, which turns on the sprinklers connected to it. When these sprinklers have run for their programmed time, the timer closes the first valve and opens the second valve. For example, the illustration below shows that station 1 is currently watering. When station 1 finishes, the timer will shut it off and start station 2. When station 2 finishes, station 3 begins, and so on. ISA Series Sprinkler T imer Timer English ISA Timer Controls and Indicators This illustration shows the programming controls on the face of the ISA Sprinkler Timer. These controls include: “Manual On” button “Advance” button Up/ Down arrow buttons LCD display Programming dial “Program A/B” button ISA Series Sprinkler T imer Timer Page 3 English INSTALL TIMER Before installing your ISA Sprinkler Timer, make sure you have the following tools and equipment: • Phillips screwdriver • Three #10 screws (1¼'' / 32mm) • 9-volt alkaline battery (not included) • 18-gauge color-coded, multi-strand, direct-burial wire for wire runs of less than 800 feet. (For runs longer than 800 feet, use 14-gauge color-coded, multi-strand, direct-burial wire). • Watertight wire splice connectors • Plastic mounting anchors (may be required for plaster or masonry walls) Page 4 Select Location NOTE:: The ISA Timer is for INDOOR use only. If you must install it outdoors, use a water-resistant cabinet, such as the Rain Bird Model TC-2 Timer Cabinet. The TC-2 is a heavy-duty, weather-resistant plastic case that lets you convert any indoor-only timer to outdoor use. Select a convenient indoor location within six feet (1,9 m) of a 120-volt AC electrical outlet (240-volt outlet for international 50 Hz models). The mounting location should be completely protected from moisture, direct sunlight, and freezing temperatures. ISA Series Sprinkler T imer Timer English Mount Timer Screw two #10 screws into the wall 4¾'' (120 mm) apart. Leave 1 8 '' to ¼'' (3,2 to 6,4 mm) of each screw head protruding from the wall. (Use plastic mounting anchors for plaster or masonry). Place the two keyhole-shaped slots on the back of the timer over the screw heads. Then slide the timer securely down onto the screws. OPTIONAL: To further secure the timer, remove the timer’s lower access cover by gently pulling the cover off using the slots on the left and right sides of the timer. Then drive a third screw through the lower middle hole. Install Battery During a power outage, the battery preserves your programmed watering schedules. A newly installed battery will hold information for up to six hours if power goes out. NOTES:: The battery serves as memory back-up only. You can program the timer on battery power, but the system will not water without AC power. Replace the battery once a year. If power outages occur frequently, you may need to change the battery more often. ISA Series Sprinkler T imer Timer Page 5 English NOTE:: When replacing the battery, DO NOT unplug the transformer or you will lose all programmed information. If the battery fails during a power outage, the timer will revert to its default watering program. The default program waters each station every day for 10 minutes, starting eight hours after AC power resumes. The default program will continue until you reprogram the timer. To install the battery, remove the timer’s lower access cover by gently prying out the cover at the slots on the left and right sides of the timer. Connect the terminals of a 9-volt alkaline battery to the timer’s two-wire battery clip. (DO NOT use a rechargeable battery). The display flashes “AC OFF” and “8:00 AM.” Replace the lower access cover, or connect field wiring as described in “Connect Field Wiring” on page 7. CAUTION:: DO NOT allow the battery to contact the timer’s terminal strip. Page 6 ISA Series Sprinkler T imer Timer English Connect Field Wiring Select Proper Wire For wire runs of less than 800 feet, use 18-gauge color-coded, multi-strand, direct burial wire. For longer runs, use 14-gauge wire of the same type. Choose wire that has one strand for each valve in your system, plus one strand for the common wire. For example, use five-strand wire if you have four valves, seven-strand wire for six valves, etc. Tape off spare wire strands for future system use or troubleshooting. Wire that is buried underground must have watertight connections and be codeapproved for underground use. Avoid placing underground wire in places where it may be damaged by digging or other activities. ISA Series Sprinkler T imer Timer Connect Valve Wires to Timer Each valve connects to the timer with two wires: a “hot wire” of its own, and a “common wire” that it shares with the other valves. NOTE:: The ISA Series Timers can be used with most hydroindexing valves. Please contact the valve manufacturer for more information. Page 7 English Remove the timer’s lower access cover by gently prying out the cover at the slots on the left and right sides of the timer. Splice together one wire from each valve (usually the white strand) to create a single “common” wire. Connect the common wire to the terminal screw labeled “COM.” NOTE:: Make sure all wire connections are tight and in firm contact with the terminal screws. Use watertight splice connectors to prevent corrosion and avoid short circuits. Connect each valve “hot” wire to a numbered screw on the timer’s terminal strip. Connect the wire from valve number 1 to terminal screw 1; connect the wire from valve 2 to terminal screw 2, and so on. CAUTION:: DO NOT connect more than one valve wire to each terminal screw. Wiring more than one valve to each terminal will damage the timer. Also, if you are using more than one timer, do not share “common” wires between them. Page 8 ISA Series Sprinkler T imer Timer English After connecting all valve wires, replace the timer’s lower access cover. NOTE:: To save water and money, you can also install a rain sensor, such as Rain Bird’s RS-1 Rain Shut Off. The RS-1 measures rainfall and prevents unnecessary watering. If Using a Master Valve or Pump Start Relay ISA 400 Series Timers allow a master valve or pump start relay to operate whenever a valve is operating. Pumps are used in some places to draw water from a well or other source. If you are activating a pump from the timer, you must also install a Pump Control Relay, such as Rain Bird’s PCR-1. The PCR-1 offers solid-state reliability and can activate most 120- or 240-volt pump motors up to two horsepower. (Optional ISA 400 Series only) NOTE:: Complete this section only if you are using a pump start relay or a master valve (an automatic valve installed on the mainline pipe upstream from the station valves). The timer does not provide the main power for a pump. ISA Series Sprinkler T imer Timer Page 9 English Connect the color-coded “hot” wire from the master valve or pump start relay to the timer terminal screw marked “MV.” Connect the common wire from the master valve / pump start relay to the common wire coming from the station valves. This wire connects to the timer terminal screw marked “COM.” NOTE:: Make sure that the total draw of the master valve or pump start relay plus the draw of the valve does not exceed 0.650 Amps at 24 VAC, 60 Hz. To avoid possible pump damage, connect a short “jumper” wire from any unused station terminal(s) to the nearest terminal screw in use. For example, if you have an eight-station timer with only four stations in use, jumper stations five through eight to the nearest active station (four). Page 10 ISA Series Sprinkler T imer Timer English Connect Transformer After installing the battery and connecting the field wires, you are ready to connect the timer’s transformer. CAUTION:: DO NOT plug in the transformer until you have completed and checked all wiring connections. Also, do not attempt to link two or more timers together with a single transformer. Remove the timer’s lower access cover by gently pulling the lower access cover off using the slots on the left and right sides of the timer. Turn the dial to RAIN / OFF. Plug the pigtail connector (located on the end of the transformer wire) into the two-prong connector to the left of the battery compartment. ISA Series Sprinkler T imer Timer Page 11 English Plug the transformer into an electrical outlet. The display flashes the hour digits and “OFF.” NOTE:: If the display does not come on, verify that the battery is new and securely connected. Turn the dial to AUTO / RUN. This completes the installation and wiring process. You are now ready to program your timer. Page 12 ISA Series Sprinkler T imer Timer English PROGRAM TIMER • • Watering days — the specific days of the week on which watering takes place (for example, Monday, Wednesday, and Friday for a “Custom” schedule), or a watering interval (for example, every third day). Start time — the time(s) of day that the program begins. This is the time that the first station in the program begins watering; all other stations then follow in sequence. ISA Series Sprinkler T imer Timer Watering duration (run time) — the number of minutes that each station runs. When programming, you can only change the field that is flashing in the LCD display. If you want to change something that is not flashing, press until the desired field flashes. Then change it by pressing the or V buttons. V Each program contains: • V Programming is the process of telling the timer when and how long you want to water. The timer opens and closes the irrigation valves according to the program you set. NOTE:: For normal timer operation, turn the dial to the AUTO / RUN position. If the dial is left in any other position, schedules will not water as programmed. Page 13 English Set Current Time and Day You must set the current time and day the first time you program the timer, and after any power interruption. Turn the dial to TIME & DAY. The hour and minute digits flash in the display. Press and the day of the week will flash. Press or V until the correct day of the week appears in the display. V Press V and the hour will flash.

Page 14 ISA Series Sprinkler T imer Timer English Select a Program (ISA Models 406 & 408 Only) ISA Timer models 406 and 408 have two programs, A and B. Each program can have its own watering schedule and start times. For example, Program A could run on Monday, Wednesday, and Friday, while Program B could run on Tuesday, Thursday, and Saturday. You can assign any station to Program A, Program B, or both. If you only plan to use one program, use Program A. The currently selected program appears in the left-hand side of the LCD display. The display will show either “PGM A” or “PGM B.” To select a program, press the Program A/B button until the program you want appears in the display. Pressing the Program A/B button switches back and forth between the two programs. NOTE:: It is easier to select one program (A or B) and program it completely before moving to the second program. ISA Series Sprinkler T imer Timer Page 15 English Pre-Set Watering Schedules For your convenience, the ISA Sprinkler Timer has six pre-set watering schedules (“C” and 1 – 5). The pre-set schedules are already programmed into the timer and are shown in the table to the right. The watering schedule you choose determines: • What days watering occurs • What time(s) watering starts (up to three different start times per day) • How long the sprinklers on each station run (duration) Once you’ve selected a pre-set schedule, you can either use that schedule’s default watering days and times, or modify the schedule to suit your own watering needs. NOTE:: Even if you want to create your own “Custom” watering schedule, you must select one of the pre-set schedules first. Then modify it to fit your needs. Page 16 Schedule Watering Days Start Times Watering Duration C Every day 8:00 am 10 minutes 1 Every day 8:00 am 10 minutes 2 Every day 6:00 am, 10:00 am, & 2:00 pm 5 minutes 3 Every other day 6:00 am 10 minutes 4 Every third day 6:00 am 10 minutes 5 Every fourth day 6:00 am 15 minutes If you want to water on specific days of the week (e.g., Monday, Wednesday, and Friday), select preset schedule “C.” If you want to water on a fixed interval (e.g., every day, every third day, etc.), select a pre-set schedule, 1 through 5.

The first selected station will begin watering immediately. When you finish selecting the station(s) you want to water, those station numbers will flash in the top of the display. After 15 seconds, the stations remaining in the top of the display will water. Each station will run for its normally programmed watering time. For dual program timers (ISA model 406 and 408), manual operation will only run the station(s) on the program (A or B) shown in the left side of the LCD. To switch programs, press the Program A/B button until the desired program appears in the display. Then repeat steps 2 through 4 to manually start the desired stations in that program. ISA Series Sprinkler T imer Timer Page 31 English Adjust Watering Percentage The Watering Percentage feature (sometimes called “Water Budgeting”) lets you increase or decrease the watering duration (run times) of all stations on both programs (A and B), without reprogramming the timer. You can set the watering percentage from 10% to 200%, in 10-percent increments. Use the Watering Percentage feature to cut back watering during cool winter months, or to increase watering during hot, dry weather. Watering percentages are calculated on the normal programmed run times for each station. For example, if a station normally runs for 10 minutes, and you set the Watering Percentage to 80%, the station will water for 8 minutes (80% of 10 minutes). If you set the Watering Percentage to 120%, that same station will water for 12 minutes (120% of 10 minutes). Turn the dial to Adjust Water %. The selected program (A or B) and the currently selected Watering Percentage appear in the display. Page 32 ISA Series Sprinkler T imer Timer English Press the or V buttons to select the desired Watering Percentage. Turn the dial back to the AUTO / RUN position. All stations will now run at the selected Watering Percentage. V WINTERIZING THE SYSTEM In cold-weather areas, you may want to turn off your timer during winter months. Before shutting down the system for the winter, make sure to drain the water from all irrigation lines to prevent freezing damage to pipes and valves. In lightning-prone areas, Rain Bird recommends that you disconnect the field wires from the timer’s terminal strip, and unplug the transformer from the outlet. This will protect the timer from lightningcaused power surges. Then turn the dial on the timer to the RAIN / )OFF position. For more information about “winterizing” your system, please call your local irrigation professional, visit our Web site at www.rainbird.com, or call 800RAINBIRD.
