If you have a power outage and the backup battery is dead you loose your settings and when it comes on with house power it has reverted to default settings. Our default settings was 6 hrs per zone.
This happened to us when we were gone for the summer. After a few weeks of noticing our sprinklers seemed to be on all day long and it was raining 3 or 4 days a week a neighbor shut off the main to the irrigation controller.
As I recall the water bill for that month was about $350.
I put in a new 9 Volt each May.
