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
8
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 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 electri-
cal codes and regulations. When used outdoors this sprinkler
timer is intended for use with a Ground Fault Interrupter (GFI)
protected circuit.
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 .

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 .
Primary Programming
Press the [RESET] to clear any previous factory programming
1. Set Clock
• Turn dial to [SET CLOCK]
• Press the [+/–] buttons to set the current time of day
Tip: To increase or decrease more rapidly, hold down either the
[+] or [-] buttons until the display goes into rapid advance mode.
• Press the [   ] buttons to set am/pm
• Turn dial to accept time
2. Set Date
• Turn dial to [SET DATE]
• Y/M/D will appear (blinking letter indicates selection)
• Press the [+/–] buttons to set the correct year, then
press [ENTER] or [   ]
• Press the [+/–] buttons to set the correct month, then
press [ENTER]
• Press the [+/–] buttons to set the correct date
• Turn dial to accept date
3. Start time
• Turn dial to [START TIME]
• Press the [+/–] buttons to select time you'd like your
watering to begin
(time will adjust in 15 minute increments)
The display will show
Please note that [START TIME] is the time of day that your
programmed watering starts . You can set up to 4 start times .
All stations that have a programmed run time (how long) will
run in sequence at these times
Note: Start-Time Stacking
When a start time is set before the previous program has
completed, that start time will be "stacked" or delayed, and will
start upon completion of the previous program.
