Orbit Model 24713 Manual

What the Orbit Model 24713 Actually Is

The Orbit Model 24713 is a basic outdoor irrigation timer. It runs on a single D-cell battery, has four station outputs, and uses a mechanical dial with a rotating schedule drum. Nothing fancy. It's the kind of unit you hook up between your spigot and your sprinkler valves when you want something cheaper than a Wi-Fi controller but more reliable than setting reminders on your phone. It's designed for residential use. Four zones, simple program structure, and a manual override switch that actually works. I've seen people try to mount these in garages, but they're not IP-rated for enclosed spaces. The plastic gets brittle after a few hot summers, and the dial mechanism sticks. Keep it outdoors under a cover.

Orbit Model 24713 Manual Download and Setup

You can find the official manual on Orbit's website under their support or products section. Search for "Orbit 24713" and look for the PDF download. Third-party sites like manualshub or manualsonline also have it, but those sometimes have outdated versions. The official one is free and doesn't require an account. If you can't find it, the current URL structure from Orbit is usually straightforward — their product pages list the manual directly below the specs. Setting it up takes about ten minutes if you haven't done this before. First, install the D-cell battery. Then remove the timer from the spigot and attach the included hose washer if you're using it in hose mode. For valve control, you'll need a 3/4-inch male pipe adapter and Teflon tape. Thread it onto the spigot, attach the timer, and hand-tighten with channel locks. Don't over-torque the plastic housing or you'll crack it. The dial on the front controls the program schedule. You set start times by pushing tabs on the rotating drum. Each tab represents a thirty-minute window across a twenty-four-hour cycle. There are sixteen tabs total, so you can schedule up to sixteen start times across your four zones. Zone A gets tabs one through four, zone B gets five through eight, and so on. This is where people get confused.

Common Problems and What I've Learned Dealing With Them

The biggest issue with this timer is the dial mechanism jamming. After about two years of outdoor exposure, the internal gears grind and the program drum won't advance smoothly. I ran into this with a unit I installed at a client's property in central Texas. The tabs were set correctly, but the dial was stuck halfway between positions. The irrigation system was watering zone A continuously because the dial wouldn't advance past that point. The workaround is to power the unit down, remove the front cover by unscrewing the four Phillips screws on the back, and gently clean the gear assembly with compressed air. Sometimes a small amount of silicone spray on the rotating shaft helps. If the gears are already worn, you're better off replacing the timer. Replacement units run about forty dollars retail. Another thing nobody mentions is the battery drain. This timer draws enough power to kill a standard alkaline D-cell in about four to six months in hot weather. If you live somewhere that gets above ninety degrees regularly, switch to a lithium D-cell. They last significantly longer and don't leak. I've seen too many corroded battery compartments from people who ignored this.

The manual override on this model is a three-position switch: Off, On, and Auto. A lot of people don't realize that "On" holds all four zones open simultaneously. It's useful for flushing lines or testing a valve, but if you leave it there and walk away, you will flood your yard. The switch clicks into place firmly, which is good, but the detent can wear out after heavy use. I always recommend treating the override as a temporary setting and resetting it immediately after.

What the Manual Doesn't Tell You

The manual covers basic operation, but it doesn't address a few practical issues that come up in the field. For one, the minimum cycle time between zone changes is about three seconds. If you program two zones with back-to-back start times that are less than thirty minutes apart, the timer will try to switch immediately and may not fully close the previous valve before opening the next one. This causes water hammer and can damage cheap solenoid valves. Spread your zones out or accept that adjacent zone times might overlap slightly. Second, the timer has no rain delay feature. If it rains heavily during a programmed cycle, nothing stops it. I've dealt with customers who complained their electric bill went up because the irrigation kept running through storm events. The solution is either a separate rain sensor wired in-line or a smart controller upgrade if this becomes a persistent problem. Third, the program drum tabs are plastic and snap off relatively easily. If one breaks, that time slot is gone. I've seen entire drums lose tabs from aggressive scheduling adjustments. Keep a small flathead screwdriver handy when reprogramming and be gentle with the tabs. Don't bend them back into place — they won't hold.

When to Upgrade Instead

The Orbit 24713 is adequate for small yards with four or fewer zones and simple watering needs. If you have more than four zones, need varying run times per zone, or want weather-based adjustments, this unit won't work. The four-station limit and fixed thirty-minute scheduling increments are hard constraints. There's no way around them. For those cases, the Orbit B-hyve series or even a basic Rachio controller gives you variable run times, zone-level scheduling, and weather integration. The tradeoff is cost and complexity. The 24713 costs around thirty dollars and works even if the internet goes down. A smart controller costs two hundred to three hundred and requires setup, pairing, and occasional firmware updates. Both approaches are valid depending on your situation. If you stick with the 24713, replace the battery annually regardless of whether it seems dead. A dropping voltage causes the internal clock to drift, which shifts your scheduled times by fifteen to thirty minutes over the course of a season. That's enough to water at the wrong time of day and waste water through evaporation. Setting a calendar reminder to swap batteries every spring and fall takes about fifteen seconds and prevents most headaches.
