system when not in use .
MULTIPLE

A controller feature that allows a program to be operated multiple times on the same
watering day .
OVERLAPPING PROGRAMS
When a “Start Time” is set for a program before the previous program has completed .
PROGRAM

Individual programs as set by the user . Each program operates independently . If one
program overlaps the other the programs will be “stacked .” After the first program
finishes the next program will begin .

duration .
SOLENOID
The electrical part on an irrigation valve that opens and closes the valve .

Section 5: Reference
• 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 .
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 controller .
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 controller has a built-in
transformer that must be connected to an AC line voltage source.
