    ....and don't forget, it takes 97.28 acre inches to make a hectare meter.

    Actually it is generic for scheduling any controller, but it also kicks out the settings for ET Manager. It is the Irrisoft insite scheduling software repackaged for Rain Bird.

    Ah, yes the Irrisoft Insite software is a good free scheduling package.

    Do you know your precip rates by zone? If you have that info and the amount of irrigation required by week it is simple math to figure out run times.
