Gardena Classic multi-channel irrigation computer 4030

The GARDENA Classic Irrigation Computer 4030 is used for the automatic control of larger irrigation systems, usually sunken irrigation systems, such as the GARDENA Sprinklersystem. The Classic Irrigation Computer 4030 is ideal for when the water quantity is insufficient for simultaneous operation of the entire system - which usually consists of several irrigation systems. Even with varying water requirements for individual plant areas, this system regulates the individual watering intervals per channel, allowing individual and optimal watering. The Classic Irrigation Computer 4030 is intended for connection of up to four 24 V irrigation valves (Art. No. 1278-20). For flexible irrigation programming, up to three programs per valve can be stored. The watering days and cycles can be selected individually. The watering duration can be set between 1 minute and 3 hours 59 minutes and can be set centrally from 0 to 200 %. If watering is to be started immediately, the system can also be activated manually. The large and clear display with user instructions makes programming simple and intuitive. Through the main channel, the GARDENA Pump Relay (Art. No. 1273-20) can be connected so that a pump can be controlled as an alternative water supply. The GARDENA Classic Irrigation Computer 4030 can be used indoors, e.g. in the garage, or in covered areas; it has a power connection of 230 V. The Irrigation Computer can be protected against power failure through a 9 V alkaline battery, so that the system always works reliably and safely (battery not included). Where required, a GARDENA Rain Sensor or Soil Moisture Sensor can be connected for water-saving operation.
