Its about a 6 month old system, newly installed, hasn't given any problems except for the ------ on the display.
I thought the only battery that the ESP ME used was just for the crystal display, and that is supposed to last many years.
What does it mean "when using a 9V battery for remote programming"?
We don't leave the ESP ME plugged in 24/7 because someone in our family has EMF sensitivity and prefers to leave it unplugged. Could that have drained the battery?
thanks,

Plug it back in. Leave it plugged in. EMF sensitivity of any sort is not going to be exacerbated by a sprinkler controller. The current involved is not enough to generate EMF. Light bulbs would generate more EMF. In fact, the currents flowing in the controller electronics are so low, the controller itself has some EMF sensitivity, and is not to be installed adjacent to large motors, or anything else capable of high EMF.
If the EMF-sensitive person persists in unplugging the controller, get an outdoor version of the controller and have it wired directly to the appropriate branch circuit.
The 9-volt battery will drain in a week or so, if the AC power is disconnected. The battery's job is to keep time (and sometimes maintain the programming) - it's strictly for backup during power outages.
