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.

Figure 1: Use Mounting Template (included)

Figure 2: Hang timer on screw using keyhole

Figure 3: Wiring Electric Valves
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.
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.

Figure 4
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)
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.

Figure 5: Using a Junction Box
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.
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.
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.
Press the [RESET] to clear any previous factory programming
Tip: To increase or decrease more rapidly, hold down either the [+] or [-] buttons until the display goes into rapid advance mode.
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.
Example: Bill just planted new grass seed and wants to water three times per day. He sets START TIME 1 for 5am, START TIME 2 for 12pm, and START TIME 3 for 5 pm.
He also sets HOW OFTEN to INT (interval) EVERY 1 DAYS (see section 3, HOW OFTEN).
In AUTO mode the system will water 3 times per day. Once Bill's sod is established he can CLEAR start times 2 and 3 and return to watering just once per day.

STATION is the area that will be watered by each valve. On this screen the RUN TIME or duration for each station is set.
There are 3 options provided:

Example: An interval of 1 will water every day; an interval of 3 will water every 3rd day, etc.
Example: Odd: 1st, 3rd, 5th, etc.
Example: Even: 2nd, 4th, 6th, etc.
Turn the dial to [AUTO] and that's it! You have programmed your timer!
Turn dial to [AUTO] to activate your program
Note: If your program is lost, the factory installed fail-safe program will turn on each station every day for 10 minutes
Note: Your prior programming will not be disturbed unless altered. Always be aware of the program you are in [A, B, or C] when you are making changes.
If you want to review or change the start times, run times, or how often to water, simply follow the directions again for that option. After reviewing or changing a watering schedule, remember to turn the dial back to [AUTO] for automatic operation.
[RAIN DELAY] allows you to delay your sprinkler timer from watering for a set period of time. Delay settings are 24, 48, and 72 hours.

Water Budgeting is a simple way to adjust your watering duration to match seasonal watering needs. Water Budgeting works by increasing or decreasing watering duration for all stations in each program. Press the [PROGRAM] button to select the program you wish to budget.
Adjustment range is from 10% to 200% by increments of 10% The default value is 100% . The budgeting will remain on the adjusted range until you change it.
To set budgeting:

Example: Bill's watering duration is set at 60 minutes however; it is the spring time so he wants to water half as long so he sets his budgeting to 50% his timer will now water for 30 minutes.
Your timer has the ability to allow you to manually water without disturbing the preset program.

Note: If the run times have not been set, the timer will not initiate manual watering and the screen will return to the current time.
Example: To manually water on station 3 for five minutes, press the [MANUAL] button then press the [◀▶] buttons until you see station 3; using the [+/-] buttons, set duration to five minutes; press [ENTER].
Note: After the [MANUAL] button has been pushed, if a selection is not made within 5 seconds all stations and programs will begin watering using the programmed RUN TIMES. If no RUN TIMES have been set, nothing will happen and the display will return to the time of day.
Note: Refer to your rain sensor manual for specific wiring instructions.
This sprinkler timer is equipped with a sensor override "on/ off" switch. This switch is for use during maintenance and repairs, so the sprinkler timer can be operated even if the rain sensor is in active mode.
Important: If the rain sensor switch is in the "on" position and no sensor is connected, the sprinkler timer will not operate. To resume sprinkler timer operation place the switch in the off position

Figure 6: Connecting a Rain Sensor
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.
Timer requires a CR2032 Lithium battery

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.
