5. Activate Battery
One Lithium CR2032 battery (included) is required to retain the
program in memory during power loss . Annual replacement is
recommended .
Remove the plastic strip to activate the pre-installed battery .
(See page 12 for battery replacement)
Note: The battery alone will not operate the valves in your
sprinkler system. The sprinkler controller has a built-in
transformer that must be connected to an AC voltage source.

A note about multiple programs
The HRC 100 C provides the flexibility of using 3 independent
programs (A, B, C) . A program is where you store all of your
sprinkler settings . It consists of a group of stations set to
specific start times and run times . Multiple programs allow
you to run different valves on different days with different run
times . While many applications only require one program (A),
using multiple programs can be useful for drip areas, newly
planted lawn, or rotary sprinkler stations . Using programs
to group stations with similar water needs will maximize
irrigation efficiency .
Primary programming can be accomplished in just a few steps .
