With 3 programs, 4 start times available per program, and advanced watering cycles, it’s easy to see why programming a Rain Bird ESP timer can be a daunting process.
I’ve been getting many questions lately about the use of the program selector switch on the Rain Bird ESP timer. There is a common misunderstanding that if you leave the selector/slide switch on a certain program, that it becomes the only program the timer will water.
If you click on the image on the left for a larger view, notice that the selector switch is positioned on program A. I also have information on programs B & C that will water even though the selector is positioned on program A.
Let’s look at an example:
- I move the program selector/slide switch to program A.
- I input station run time for valves 1-4 on program A with a start time of 6 AM, and I set the water days to the custom cycle to water on Tuesday, Thursday, Saturday, and Sunday.
- If I move the dial back to Auto the timer will water all of the information I just entered on program A.
- I move the selector/slide switch to program B.
- I input station run times for valves 5 & 6 with a start time of 2 PM, and I set the waters days to cyclic to water every other day.
- If I leave the selector/slide switch on program B and return the dial to Auto, not only will the timer water every thing I entered on program B, the timer will also water everything I entered on program A.
After reading through the manual again on the ESP timer I agree that Rain Bird doesn’t do a good job of explaining what the switch does after you input programming onto the different programs on the timer. I would suggest they add the line of text I have above or something similar to help users better understand the programming process.
I’ll remind you one more time here, no matter where the selector/slide is positioned, whenever you move the dial to the Auto position, the timer will try and water all the information you have input in the various programs.
