9V Battery
9V Battery
CONNECTING THE BATTERY (OPTIONAL) .........................................................................
Connect a 9-volt alkaline battery (not included) to the battery terminals
and place in the battery compartment in the controller cabinet. The
battery keeps time during power outages and allows the user to
program the controller without AC power. Watering will not occur
without AC power. Since this controller has nonvolatile memory,
the program will be retained during a power outage even if no battery
is installed.
