Product Description The GARDENA Programming Unit provides automatic control of irrigation computers or larger sprinkler systems, making it ideal for use in areas without a power connection. The unit is perfect if the water quantity is insufficient for simultaneous operation of the entire system, which consists of several irrigation systems. Even with varying water requirements for individual plant areas, the GARDENA Programming Unit regulates the individual irrigation intervals per line, allowing for separate and optimal irrigation. The GARDENA Programming Unit is used to program the GARDENA Control Module (art. no. 1250). For data transfer to the control module, you only need to press a button after connection. After programming, the control module is mounted on GARDENA Irrigation Valves 9 V (art. no. 1251-20) and the module then controls them based on set times. Up to six irrigation activities can be selected per day. The irrigation days and cycles can be programmed individually; the duration of irrigation can be flexibly set between one minute and 9 hours and 59 minutes. This device operates on one 9 V alkaline battery (not included). It lasts approximately one year. --discontinued-- replacements are G1285, G1287
