Watering your lawn is something you’re forced to do if you want to keep your grass healthy and green throughout the summer. This is where having a sprinkler system can be a huge benefit, as it allows you to handle the task automatically.

However, a sprinkler system is nothing without a sprinkler controller, and it’s important to carefully consider your choices to ensure you choose a controller that fits your sprinkler system and your needs.

How Does a Sprinkler Controller Work?

Also known as a sprinkler timer, the sprinkler controller is the most important part of an automatic irrigation system, as the controller is responsible for turning each zone of the sprinkler system on and off automatically. Without a controller, you’d be forced to turn your sprinkler system on and off and switch between zones by hand, which can present all sorts of problems should you be out of town for a few days.

Sprinkler controllers contain a circuit board that activates an electronic valve in order to allow water to flow into the specific zone. Each zone in the system has its own valve, and you can set the system so that each zone is activated in sequence to water the entire lawn over the course of a few hours.

With the controller, you can set the time and specific watering program for each zone. After the set amount of time has lapsed, the controller turns off the power to the zone to stop the flow of water and then activates the electricity to open up the valve and thus water the next zone.

Classic Sprinkler Controllers

In the past, the vast majority of sprinkler controllers were either basic electromechanical models or electronic models. Electromechanical controllers are by far the simplest type, which work by either turning dials or flipping a switch to turn the system on and off. These systems are very reliable and have the advantage of being unaffected by power outages, but they’re generally not recommended as they don’t allow you to set independent watering requirements for various zones.

Electronic controllers are the more common type of timer, and these timers have the advantage of allowing you to program different watering requirements for each zone. With this type of controller, you can vary the frequency or length of the watering to accommodate for differences in drainage, soil condition and sun exposure. These timers also typically feature a rain delay function that allows you to stop the program whenever rain is expected to avoid overwatering.

With these classic electronic timers, everything is set directly from the controller panel. Unfortunately, this has the drawback of making it impossible to adjust your watering programs and schedules when you’re away. For this reason, more and more homeowners are beginning to turn towards Wi-Fi controllers or so-called smart sprinkler controllers.

Wi-Fi Sprinkler Controllers

Wi-Fi controllers have a number of major advantages in that they can be controlled directly through an app on your smartphone. These systems connect to your home Wi-Fi network, which allows you to set and adjust the programs from anywhere in the world.

Compared to the small display and buttons on a classic controller, programming and adjusting your sprinkler system via your computer or smartphone is generally far easier and more intuitive.

These smart controllers also allow you to take advantage of automatic weather adjustments, which has been shown to be a major help in lowering your water bills. However, you need to be aware that these systems will only work when your Wi-Fi network is working, and you won’t be able to program the control or take advantage of the automatic weather adjustments if your local network is down.

What to Look for in a Sprinkler Controller

When looking for a sprinkler controller, no matter whether you’re in the market for a classic controller or a smart controller, it’s essential that you focus on quality. There are a huge number of controllers on the market, but not all of them are worth the materials they’re made of. Buying a high-quality controller will allow you to remain confident that your sprinkler system will continue to function properly whenever you’re away from home, which should allow you to maintain a healthy lawn.

Sprinkler controllers are designed with a specific number of zones, and it’s important that you choose a controller that fits your specific sprinkler system. Obviously, a controller than only has six or eight zones won’t do you much good if your irrigation system is divided into 10 zones.

If you’re in the market for a Wi-Fi controller, you’ll have the option to choose a controller that can only be programmed through the accompanying app or one that also features a back-up screen to allow you to also program it directly from the controller itself.

There is no doubt that using a sprinkler controller is something every homeowner should consider. Statistics from the EPA show that using an automatic sprinkler controller can cut down on your water usage by approximately 50 percent, while installing an EPA WaterSense approved controller saves the average home nearly 8,800 gallons of water per year. Nonetheless, it’s still essential that you choose the right sprinkler controller for your system in order to fully take advantage of these water-saving benefits.
