Installation

Section 2:  Required Tools

• Phillips Screwdriver
• Wire Strippers

1. Select a Location
   When choosing a location for your timer, consider the following:

2. Choose a location near an electrical outlet.

3. Ensure operating temperatures are not below 32° or above 158° Fahrenheit (below 0° Celsius or above 70°Celsius).

4. Locate the timer where there is easy access to the sprinkler wire (from valves).

5. 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 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 a 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 corners of the cabinet. See figure 2

6. Connecting the Timer to Valves
   Wiring Electric Valves
   Taking the sprinkler wire, strip 1/2” (12 mm) of the plastic insulation off the end of each individual wire. Connect one wire from each valve (it doesn’t matter which wire) to the “Common” sprinkler wire (usually white in color). Next connect the remaining wire from each valve to a separate colored sprinkler wire. See figure 3

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: 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.
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 or Speed Seals to prevent corrosion of the connection and for protection from water infiltration.

Connecting Sprinkler Wires to the Timer
Taking the sprinkler wire, strip 1/4” (6 mm) of the plastic insulation off the end of each individual wire. Connect the “Common” sprinkler wire (usually white in color) to the terminal labeled “COM”. Next connect the remaining wires to a separate terminal. See Figure 4
To avoid electrical hazards and damage to the timer, only one valve should be connected to each station. See Figure 4

Programming with Easy-Set Logic™

Section 3: A note about multiple programs
Your sprinkler timer provides the flexibility of using 2 independent programs (A, B). The programs are where you store all of your sprinkler settings. Each program 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 (A, B) 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 1-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 at each program if you want to water more than once per day. All stations that have a programmed run time (how long) will run in sequence at each start time.
     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 sets the INT (interval) to water 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.

4. Run Time

   • Turn the dial to [RUN TIME].

   • Press the PROGRAM button to select which program you’d like to set.
     STATION is the area that will be watered by each valve.
     STATION is the area that will be watered by each valve.

   • Press the buttons to move from one day to another.

   • Press [+] or [ENTER] to select a day for watering. A frame will appear around the selected days..

   • To delete a previously entered day, press [-] or [CLEAR].
     Example: Monday, Wednesday, & Friday
     Intervals

   • Use the buttons to move to the INTERVAL option “INT”.

   • Press [+/–] buttons to select the number of days between watering.
     Example: An interval of 1 will water every day; an interval of 3 will water every 3rd day, etc.
     Odd or Even Days

   • Use the buttons to move to the ODD or EVEN day watering.

   • Press [+] or [ENTER]

   •  Selecting a different option or pressing clear will erase the previous selection.
     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 or B) when you are making changes.

Reviewing and Changing Your Program
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.

Additional Features

Section 4: Rain Delay
[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.

• Turn dial to [AUTO]

• Press the [RAIN DELAY] button to automatically delay watering for 24 hours.

• If a longer Rain Delay is desired, press the [+/–] buttons to increase or decrease the setting.

• Press [ENTER] or wait 10 seconds and the selected rain delay will begin.

• [CLEAR] button stops the rain delay and scheduled watering will resume.

• At the end of the selected rain delay amount of time, automatic watering resumes.

• While in rain delay mode, the timer display will switch between the actual time and the remaining hours of the delay, every 2 seconds.
  Manual Watering
  Your timer has the ability to allow you to manually water without disturbing the preset program.

• Turn the dial to [AUTO].

• Press the [MANUAL] button. Display will show A B and ALL. After a few seconds or by pressing
  [ENTER] the timer will begin manual watering.

• All stations will water consecutively for their programmed duration.
  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.

• To specify a specific program or station, Press the buttons to select A or B.

• Press [ENTER] to activate.

• To select a specific station, continue pressing the buttons until desired station number appears.

• Press the [+/–] to enter the desired duration from 1 to 240 minutes.

• Wait 5 seconds and your station will begin.

• To stop Manual Watering press [CLEAR].

• The timer will go back to your original automatic watering schedule.
  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.
  Connecting a Rain Sensor

• Connect the rain sensor wires to the wiring terminal ports (yellow in color) labeled “Sensor” (see figure 6).
  Note: Refer to your rain sensor manual for specific wiring instructions.

• Place the sensor on/off switch to the “on” position to begin operation.

Rain Sensor Bypass
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.

Replacing the Battery
Your timer requires a CR2032 Lithium battery.

• The battery will maintain your program in case of an AC power loss.
• The 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 transformer must be connected to an AC line voltage source.
