Required Tools
  • Phillips Screwdriver
  • Wire Strippers
Installation Steps
  1. Select a Location
  2. Mount the Timer
  3. Connect Valve Wires to Timer
  4. Connect Electrical Power
  5. Activate Battery

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.

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

Figure 1: Use Mounting Template (included)

Figure 2: Hang timer on screw using keyhole

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.

Only connect one valve to each terminal (station)

Orbit-57894-27896-Timer-User Manual-8

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.

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.
