The GARDENA Programming Unit serves the automatic control of Irrigation Control Systems or larger Sprinklersystems, and is therefore ideally suited for use in areas without power connection. It is ideally suited for when the water quantity is insufficient for simultaneously operating the entire system – comprising several irrigation systems. Also with varying water requirements of individual plant areas, the GARDENA Programming Unit controls the individual watering intervals per pipe and thereby allows individual and optimal irrigation. The GARDENA Programming Unit serves the programming of the GARDENA Controller (Art. No. 1250). Data transfer to the Controller is easily made after connection by pressing a button. After programming, the Controller is mounted on GARDENA Irrigation Valves 9 V (Art. No. 1251-20) and then controls them based on the set times. Per day, up to six watering activities can be selected. The watering days and -cycles are individually programmable; the watering duration can be flexibly set between one minute and 9 hours 59 minutes. For operation, one 9 V alkaline battery is required (not included). This ensures secure operation for about one year.
