An irrigation controller is a device that automatically manages the operation of an irrigation system. It starts and stops the water supply according to a set schedule, regulates the watering duration, and sequentially activates individual zones. Thanks to automation, plants receive the necessary amount of moisture without constant supervision from the property owner
What should you pay attention to when choosing one?
Before purchasing a controller on the website: waterday.com.ua/avtomatychnyi-polyv/systemy-keruvannia/kontrollery/ , you need to determine the number of irrigation zones. One zone usually combines equipment with the same water consumption and operating mode. For example, lawn sprinklers and drip tubing should preferably be connected to different zones.
You should also consider:
expandability — the possibility of connecting additional modules in the future;
the number of programs — for creating different watering schedules;
sensor support — rain, soil moisture, or freeze sensors;
control method — buttons on the unit, a mobile app, or a web interface;
installation location — indoors or outdoors;
power supply type — mains electricity or batteries;
compatibility with valves and other irrigation system equipment.
What is an irrigation controller used for?
In an automatic irrigation system, the controller serves as the central control unit. At a specified time, it sends a signal to solenoid valves that open or shut off the water supply. Each valve is responsible for a separate zone: a lawn, flower bed, garden, greenhouse, or drip irrigation line.
Using a controller makes it possible to:
automatically start watering on specified days and at specified times;
set the operating duration of each zone separately;
water the property early in the morning or at night;
reduce unnecessary water consumption;
maintain a stable level of soil moisture;
pause the system during rain or unfavorable weather conditions.
How to configure a controller for efficient watering?
The duration and frequency of automatic irrigation in Dnipro should be set taking into account the type of plants, soil composition, weather conditions, and equipment capacity. A lawn is best watered less frequently but intensively enough for the water to reach the root system. For drip irrigation, longer cycles with a low water flow are usually used.
During hot weather, the program should be adjusted according to the plants’ needs, while watering should be temporarily suspended after rainfall. Connecting a rain sensor or using weather-based control helps prevent unnecessary system starts.
Advantages of automatic irrigation control
A properly selected controller makes the irrigation system convenient, economical, and predictable. The owner does not need to manually open taps or move hoses between different parts of the property. Automation ensures regular care of the lawn, garden, flower beds, and greenhouses even during a prolonged absence of the owners.
When choosing a device, it is advisable to allow for a small reserve in the number of zones. This will make it possible to expand the system in the future without replacing the main control unit. If the property has a complex layout, it is better to select the optimal model and connection scheme together with an automatic irrigation specialist.
