HYDRO-RAIN HRC 100-C User Manual

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 basic
steps.
