'Electronic control unit with modifiable pre-set programs for the control of automatic watering systems with plural lines'

摘要

An electronic control unit for the control of automatic watering systems having plural lines comprising an electronic circuit with a programmable processing unit (83) for the control of a plurality of different watering lines. A manually operated selector (59), preferably of the rotary type, is provided, that is settable in a plurality of selectionable positions (1-28), to each one of which a specific watering cycle for said lines corresponds. By acting on the selector (59) and on a start button (62), it is possible to modify the programming of the processing unit (83) in order to associate with each single line a respective watering cycle different from the ones otherwise selectable by means of the selector (59).
