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.

Claims

1. An electronic control unit with one or two ways controlled by electrovalves for programmed watering of lawns, gardens, flower boxes and similar spaces, comprising a front panel, a display, watering program selection push-buttons for selecting the watering duration and repetition frequency and an electronic micro controller controlled by said selection push-buttons and connected to said display so that, in response to the operation of said selection push-buttons, the micro controller controls the visualization of the duration and the frequency of the selected program, characterized by further comprising at least one start push-button for immediate or delayed starting of the selected program, said start push-button being associated to said micro controller so that, in response to a single operation of said start push-button, the micro controller controls the immediate start of the selected watering program, while in case of operation of the start push-button for a variable number of times programs the delayed start of the selected program.

2. The electronic control unit according to claim 1, characterized in that, in response to a single operation of said start push-button, the micro controller also controls the visualization of the time to the end of watering.

3. The electronic control unit according to claim 2, characterized in that, in response to the operation of said start push-button for a variable number of times, the microcontroller also controls the visualization of the time to the start f the watering.

4. The electronic control unit according to claim 1, characterized in that said microcontroller also controls the visual representation of the waiting time from a watering operation and the next one.

5. The electronic control unit according to claim 1, characterized by comprising also a push-button for actuation of a manual watering start mode for a prefixed time.

6. The electronic two-way control unit according to claim 1, characterized by comprising two start push-buttons used for association of the selected program to one or another of two electrovalves for control of the two ways and for the immediate or delayed start of said selected program.

7. The electronic two-way control unit according to claim 6, characterized by comprising a manual watering start mode which can be actuated by simultaneous operation of said start push-buttons.

8. Electronic The electronic control unit according to claim 6, characterized by comprising a mode of simultaneous actuation of the watering programs of the two electrovalves and a mode of non-simultaneous actuation a of the watering programs of the two electrovalves.
