Replacing the Battery
Timer requires a CR2032 lithium battery
• The battery will maintain your program in case of an AC
power loss
• Battery should last approximately one year
• Open by sliding the battery tray out to the right
• Insert one CR2032 battery into the compartment with
the + side up
• Slide back into place.
PROGRAM
RAIN DELAY
A weak or missing battery can cause the time, date, and
program to be erased after a power failure . if this happens,
you will need to install a fully charged battery and reprogram
the timer .
Tip: Replace battery every year, to avoid loss of programming
Note: A battery alone will not operate the valves in your sprinkling
system. The sprinkler timer has a built-in transformer that must
be connected to an AC line voltage source.
