I am using open sprinkler DC for a splash pad. At times we would like to run multiple sprays during the program cycle. In the middle of the program cycle we would like to run the some of same sprays at the same time. Then also in the cycle some of the sprays come on at other than the fixed sequential negative delay. The problem with manual setting is they come on only at the beginning of the cycle.
In other words sprays could be turned on at any sequence after the Program Switch.
See the attached timing diagram as an example
