Nelson smart zone

I have a smart zone ez. Not sure of model,think its some kind of 8500 number. I changed the battery and reset it,but it will only run a 3 min test. And it doesn't shut off. The system seems to run only on the batt. After 2 days the display is blank. I just bought the house and I think the controller is no good. How do I know if its getting power? I know the outlet is working,but I think the cont. is not getting power. It doesn't run any programs. Should I try to reprogram it? Or would this be a waste of time. When I reset it shouldn't itbrun a program if its getting power? Thanks, Artie.

the controller can 'operate' on battery power, but that doesn't make the zone valves work, since they require 24VAC

How many zones do you have?
