For individual, automatic, and water-saving irrigation

The GARDENA Water Control Master gives a high level of flexibility and individual customisation to your garden irrigation. Up to six different, independant schedules can be created, and the start time, duration and weekdays of the irrigation can be adjusted to best suit your needs. The control is battery-operated and is connected directly to the tap. Programming is straightforward, with the rotary turn and push switch for selection of the data and confirmation. An easy-to-read, fully graphic LC display shows all settings at a glance, with menu selection in 10 languages. The weatherproof operating unit can be removed for convenient handling. It is easy to centrally adapt the watering duration, or to stop all irrigation during a phase of bad weather. The unit is ideal for controlling the GARDENA Water Distributor automatic, and can also be used in combination with a GARDENA Soil Moisture Sensor.

    Automatic and time-saving irrigation

    Using a GARDENA Water Control, your garden can be reliably and conveniently watered – even if you are not at home. Resulting in more leisure time, a lush green lawn and beautiful, healthy plants. If the automatic irrigation system is started in the early morning hours or the evenings, less water evaporates. This saves money and ensures targeted, optimised irrigation.

    Flexible irrigation with 6 schedules

    Six independent schedules can be created for irrigation purposes. The start, duration and weekdays of the irrigation can be adjusted. Highly flexible plans can be set according to your personal tastes. Plant connoisseurs use this for example for additional pre-watering which prepares the soil and roots for the later, main irrigation. This improves the water absorption and plant growth.

    ‘Safe Stop’ technology

    The Water Control always works reliably due to the ‘Safe Stop’ technology. If the energy levels of the battery are too low to completely control an irrigation process, then this process is not commence. The battery level indication in the display also tells you when the battery has to be replaced.
