4. Connect Electrical Power
5. Activate Battery
ENGLISH

6
1. Select a Location
When choosing a location for your HRC 100 C, consider the
following:
•Choose location near a power source (if hard wiring) or
electrical outlet when using the supplied power cord.
•Ensure operating temperatures are not below 32° or
above 158° Fahrenheit (below 0° Celsius or above 70°
Celsius).
•Place it away from direct sunlight if possible.
•Ensure at least 9” of space to the left of the sprinkler
controller box for the door to swing open after
installation.
•Locate the controller where there is easy access to
sprinkler wire (from valves). If mounted in an outdoor
location, shut the compartment door to keep the
controller safe from weather damage. To lock: insert
the key and turn clockwise to the locked position.
Note: Sprinkler controllers are weather-resistant to UL-1951
and ETL® Listings, but should not be placed in areas where
continuous water could cause damage.
2. Mount the Controller
•Use the mounting template (included) to mark the
mounting screw location on the wall. See figure 1
•Install a No. 8 screw (included) into wall in the upper
template location. Leave the screw head protruding 1/8”
(3mm) from wall. Use expanding anchors (included) in
plaster or masonry, if necessary, for a secure hold.
•Slip the HRC 100 C over protruding screw (using keyhole
slot in back). See figure 2
•Drive a No. 8 screw through one of the two pre-formed
holes located in lower back cabinet. See figure 2
3. Connect Valve Wires to Controller
•Strip 1/2” (12 mm) of the plastic insulation off the end of
each valve wire at the controller.
•Connect one wire from each valve (it doesn’t matter
which wire) to a single “Common” sprinkler wire (usually
white).
•Connect the remaining wire from each valve to a
separate colored sprinkler wire.
See figure 3
Note: The maximum loading for each station/pump is 250mA,
the maximum loading for the controller is 500mA.
If the distance between the sprinkler controller and valves is under
700'(210 m), use sprinkler wire or 20 gauge (AWG) plastic jacketed
thermostat wire to connect the sprinkler controller to the valves. If
the distance is over 700'(210 m), use 16 gauge (AWG) wire.
Important: All wires should be joined together using wire nuts,
solder, and/or vinyl tape. In wet environments like a valve box it
is recommended to use grease caps to prevent corrosion of the
connection and for protection from water infiltration.
Wiring Electric Valves
Strip 1/2” (12 mm) of plastic insulation off the end of each
individual wire. Each valve has two wires. One wire (it doesn’t
matter which one) is to be connected as the common. The

other valve wire is to be connected to the specific station
wire that will control that valve. The common wires for all the
valves can be connected together to one common wire going
to the controller. To avoid electrical hazards, only one valve
should be connected to each station. See figure 4
Important: The wire can be buried in the ground; however, for
more protection wires can be pulled through PVC pipe and buried
underground. Be careful to avoid burying the wires in locations
where they could be damaged by digging or trenching in the future.
Your controller is equipped with the simple “push-in” terminals
for easy connection. Connect common wire to the common
terminal. Connect remaining wires to corresponding terminal
locations.

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.
Section 3: Programming with
Easy-Set Logic™
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.

4. Connect Electrical Power
Indoor Locations – Insert the power cord into an 110V electrical
outlet.
Outdoor Locations – If a covered Ground Fault Interrupter (GFI)
outlet is available, insert the power cord into the 110 volt outlet.
If no outlet is available, the controller must have the wiring
permanently installed (*see figure 5)
•Turn off the AC power at the AC circuit breaker and
apply an appropriate safety lockout. Verify that the power
has been turned off to the installation site using an AC
voltmeter set for the correct measurement range.
•Use power feed wire of 14 gauge (AWG) minimum with
a temperature rating of 155 degrees Fahrenheit (68
degrees Celsius) or higher.
•Install the conduit and associated fittings. Connect the
AC electrical power wiring to the source by following all
the right codes and local standards.
•Connect the junction box to the controller using a ½”
nipple (Junction box and nipple not included). [See Figure
5] Connect the source power conduit to the entrance of
the junction box, following all the appropriate codes.
•Take the cord (running from the controller to the junction
box) from the junction box and cut it to length. Remove the
outer insulation (from cord) to expose the three wires.
•Connect the source wires to the wires extending from the
sprinkler controller.
•For USA: Take care to follow the correct color code.
Connect the, Black for Live, and White for Neutral, there
is no ground connection required.
•Make sure all connections are made with code-approved
insulated connectors.
•Be sure to place a weatherproof gasket and lid on the
junction box.
•Turn AC power on at the AC circuit breaker.
Important: Installation Using Permanant Wiring
The sprinkler controller has a built-in transformer that must be
connected to an AC line voltage source. Check the back of the
sprinkler controller box for power requirements. Local building
and electrical codes usually require that an approved electrical
conduit and electrical fittings be used to connect exterior wall-
mounted equipment to AC power. Please check local codes. Any
permanent connection should be made by a licensed electrical
contractor in accordance with the requirements of the National
Electrical Code and other state and local codes.
This sprinkler controller has two holes at the bottom for wire
access. Use a 1/2” Nipple to connect the sprinkler controller to
a standard electrical junction box. Both connector and junction
box must be UL Listed or equivalent or comply with IEC or EN
standards or equivalent.
The wire can be buried in the ground; however, for more
protection wires should be pulled through electrical conduit and
buried underground. Be careful to avoid burying the wires in
locations where they could be damaged by digging or trenching in
the future.
Caution: Do not connect the sprinkler controller to one phase of
a three phase power system used by a pump or other electrical
equipment.
Note: For outdoor applications it is recommended that a qualified
electrician complete the installation in accordance with electrical
codes and regulations. When used outdoors this sprinkler
controller is intended for use with a Ground Fault Interrupter
(GFI) protected circuit.
