Whoever put our system in many years ago ended up with 5 sets of cables, with 3 to 4 valves in each "valve box" based on location in the yard. They all converge at the controller, but it means I have 20 control wires, and not all are used, but I needed 5 commons; one per valve box install.
I'm hoping I can just set this up to water each zone my desired duration, no weather this or rain that - just water the stations throughout the day, and if I have a sprinkler blowout the ability to easily cut that station until the weekend.
Since we care for grandkids often, the ability to easily cancel watering if outdoor activity is anticipated is what drives getting a remote controllable unit.
