Orbit Timer What Does "off Pwr" Mean On My Sprinkler Timer?

What does "off pwr" mean on my sprinkler timer? - orbit timer

Orbit is a programmer and I went to the screen, "she says of DWR" but I have no idea what that means. Orbit Web / phone service have not helped me.
I thought I was the outlet, so I tried another, but it remains the same.
