I currently have 6 zones but have combined them into 3 so that my well pump runs continuously and doesn’t kick on and off. Does this devise have the functionality to run only 3 zones?
This should help answer your question. Thanks!
To add to the post @franz linked to, I combined 3 zones into one on two different areas of grass temporarily two years ago. Been working perfect ever since. Been too lazy to re-pipe them.
