Here are the instructions for programming the the Rain Bird ESP Series timer on the Custom Cycle. Note: The numbers in this list correspond to the graphics on the left.

1. Select the program you want.

2. Turn the dial to ADVANCED CYCLES.

3. “CUSTOM” should appear in the display. If “CUSTOM” does not appear in the display, press the UP or DOWN arrow until “CUSTOM” appears in the display.

4. Turn the dial to “MON.”

5. The display shows the day of the week and whether that day of the week is “ON” or “OFF.”

6. Press “ON” or “OFF” to change the setting for this day of the week.

7. Turn the dial to the next day of the week. Repeat steps 5 through 7 until you have set each day of the week.

8. Turn the dial to AUTO and you done!

I have two videos on my YouTube channel iScaper1 that deal with programming a Rain Bird ESP series sprinkler timer: The first is Using the Advanced Cycles feature on a sprinkler timer, and the second is How to install & program a Rain Bird ESP Series timer. Please check out these videos for visual help with programming a Rain Bird ESP Series sprinkler timer/controller.

  1. Fabulous, what a web site it is! Thiis web site presents useful data tto us, keep
    it up.

  2. I have an ESP 8si RB and am having trouble with the custom setting. When I set the schedule switch to custom, the display reflects days as if it was on a fixed schedule (i.e., it shows a 1, 2, or 3). I checked already to make sure the schedule switch is aligned with the inner black switch. It seems neither switch is holding at the Custom position. Any thoughts or suggestions?

    • After selecting the C for custom schedule does the display show the day of the week if you turn the dial to Day on Current Day and Time, or does it still display a number? I would also check that it has this same problem on program B. If it does I would guess there is something wrong with the slide switch. If I remember right Rain Bird timers have a 5 year warranty so I would call Rain Bird tech support at 1-800-RAINBIRD and explain your problem.

  3. My rainbird is programmed, but it kicks back on after 2 hours and cycles again. Can you help me figure out what I might be doing wrong? I’ve checked it over and over again to no avail.
    I appreciate your help in advance.

    • Check that you don’t have extra start times programmed in. Each program usually has 3 or 4 start times available and if you have more than one for each program this could be causing your problem. Let me know if this helps.

  4. I have a Rain Bird ESP timer that was working fine until a power surge hit it.

    My question is: Can you replace the transformer (635640A) which puts out the requisite 25.5 V AC at 1000 mA, with a Rain Bird UTI (Univeral transformer AC2550650) output same AC voltage but 650 mA?

    Any help much appreciated.

    • According to Rain Bird the UT-1 transformer will work with the following timers:

      SST Indoor: SST-400i, SST-600i, SST-900i
      STPi Indoor: STP4i, STP6i, STP9i
      E-Class: E4, E6 & E9
      ISA-304, ISA-406, ISA-408
      PC-306, PC-406, PC-406ps, PC-504 & PC-506
      ISM4-RS, ISM6-RS & ISM9-RS

      If you have an ESP timer you need to go with the 635640 transformer.
