Abstract: An electronic control unit for programmed watering of lawns, gardens, flower boxes and similar spaces, comprises a front panel, a display, watering program selection push-buttons for selecting the watering duration and the watering repetition frequency and at least one start push-button for starting the selected program. The control unit comprises an electronic micro controller which, in response to the operation of said selection push-buttons, controls the visualization of the duration and frequency of the selected program and, in response to a single operation of the start push-button, controls the immediate start of the selected watering program. If the start push-button is operated for a variable number of times, the micro controller programs the delayed start of the selected program.
