1. Select a Location
When choosing a location for your timer, consider the
following:
• Choose location near a power source (if hard wiring) or
electrical outlet (applicable only to U.S. retail timers)
• 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
timer box for the door to swing open after installation
• Locate the timer where there is easy access to sprinkler
wire (from valves). If mounted in an outdoor location,
shut the compartment door to keep the timer safe
from weather damage. To lock: insert the key and turn
clockwise to the locked position
Note: Sprinkler timers are weather-resistant to UL-50 and ETL
®
Listings, but should not be placed in areas where continuous
water could cause damage.
2. Mount the Timer
• 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 timer over protruding screw (using keyhole slot
in back of timer). 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 Timer
• Strip 1/2” (12 mm) of the plastic insulation off the end of
each wire for both the timer wires and the valve wires
• 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 timer is 500mA.
If the distance between the sprinkler timer and valves is under
700’ (210 m), use Orbit® sprinkler wire or 20 gauge (AWG) plastic
jacketed thermostat wire to connect the sprinkler timer 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 Orbit 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 bedamaged by digging or trenching in the future.
Your timer 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.
ENGLISH
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 timer 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
Your sprinkler timer 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 timer 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 Timer 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 timer 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 timer.
• For USA: Take care to follow the correct color code.
Connect the Green for Ground, Black for Live, and White
for Neutral. Often the source ground may be bare copper
conductor rather than green wire.
• For Europe: Live is Brown and Neutral is Blue, there is
no ground connection required. Be sure that all wires are
connected to the proper source wire.
• 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 timer has a built-in transformer that must be
connected to an AC line voltage source. Check the back of the
sprinkler timer box for power requirements. Local building and
electrical codes usually require that an approved electrical
conduit and electrical fittings be used to connect exterior wallmounted 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 timer has two holes at the bottom for wire access.
Use a 1/2” Nipple to connect the sprinkler timer 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 timer 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
timer is intended for use with a Ground Fault Interrupter (GFI)
protected circuit.

TIMER
Pump Start & Master Valve
This sprinkler timer allows a master valve or pump start
relay to operate whenever a station is on.
Note: If you are activating a pump from this timer, you must
purchase a Pump Start Relay. From the pump start relay (or
master valve); connect one wire to the “Pump” terminal and the
other wire to the “Common” terminal.
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.
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.
