InstallationOrbit 57894 sprinkler timer FIG- (2)

Required Tools

  • Phillips Screwdriver
  • Wire Strippers

Installation Steps

  • Select a Location
  • Mount the Timer
  • Connect Valve Wires to Timer
  • Connect Electrical Power
  • Activate Battery

Select a Location

When choosing a location for your timer, consider the following:

  • Choose a 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 the 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 positionOrbit 57894 sprinkler timer FIG- (3)

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 the 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 the keyhole slot in the back of the timer). See figure 2
  • Drive a No. 8 screw through one of the two pre-formed holes located in the lower back cabinet. See figure 2Orbit 57894 sprinkler timer FIG- (4)

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

Note: The maximum loading for each station/pump is 250mA, and 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.Orbit 57894 sprinkler timer FIG- (5)

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 be damaged by digging or trenching in the future.
  • Your timer is equipped with simple “push-in” terminals for easy connection. Connect a common wire to the common terminal. Connect the remaining wires to corresponding terminal locations.Orbit 57894 sprinkler timer FIG- (6)

Connect Electrical Power

Indoor Locations – Insert the power cord into a 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 a 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 the cord) to expose the three wires.
  • Connect the source wires to the wires extending from the sprinkler timer.
  • For the 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 conductors 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 Permanent 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 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 the 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.Orbit 57894 sprinkler timer FIG- (7)

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.

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.Orbit 57894 sprinkler timer FIG- (8)

(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.

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

      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 been 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 it 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.
  4. Run Time
    1. Turn the dial to [RUN TIME]Orbit 57894 sprinkler timer FIG- (11)

FAQs Orbit 57894 sprinkler timer

How durable are orbit sprinkler timers?

To replace the timer I bought three years ago, I ordered this one. Every other day, I used it to water the plants around my house. It is powered by two AA batteries, which can be easily changed, and last for about six months.

Why do the sprinklers in my orbit turn on twice?

Each program has multiple Daily Start Times that have been set. The program will launch at the specified time and run through each of the zones assigned to it sequentially.

How is an orbit timer troubleshooting?

To make sure the timer is correctly plugged in, check the connection to the docking port. Try taking the timer out and putting it back in after pressing down until you hear a click. If you’re still not getting electricity, there may be a problem with the timer.

What is the ideal sprinkler system schedule?

Early in the morning is the greatest time to water your grass because the temperature is cooler and the wind is usually calmer, allowing the roots to absorb the water before it evaporates. It is preferable to water between 4 and 6 p.m. rather than during the day or in the early afternoon if you cannot water in the morning for some reason.

What causes sprinklers to stop turning?

The buildup of junk in the filter is the most frequent cause of a sprinkler ceasing to rotate.

How long should each zone’s sprinklers run for?

Completely wet: Spray zones should run for 10 to 15 minutes per zone, whereas rotor zones should run for 30 to 40 minutes per zone.

Has the orbit timer a fuse?

It will keep your timer functioning as expected for some time because it is made of durable materials. contains 2 fuses.

Can two sprinkler zones operate simultaneously?

Due to restrictions on water pressure and flow at residential properties, running numerous zones simultaneously is typically not practicable. You can connect a number of solenoids or valves to the same zone output, just like with any other irrigation controller that is conventional.

What causes automated sprinkler systems to malfunction frequently?

The primary culprit is rusting, by far. An internal or exterior corrosion process might permanently bond a water seal to the frame. For this reason, NFPA 25 also mandates that you repair any sprinklers that exhibit performance-harming corrosion during the floor-level inspection.

Why does the pressure in my sprinklers drop after a while?

A leak in the zone’s lines or a leak at one or more nozzles is frequently to blame when your sprinkler system was functioning normally when one zone started to lose water pressure. Water pressure won’t be as high from leaking nozzles, which requires an easy replacement.
