Abstract

An electronic control unit for control of solenoid valves in watering systems is described, comprising a plurality of knobs (101) for the selection and the time-setting of respective solenoid valves (102) in a watering cycle, and at least one additional period knob (104) for defining the frequency of activation of said solenoid valves (102) in said watering cycle.

Claims

1. Electronic control unit for control of solenoid valves in watering systems, characterised in that it comprises a plurality of knobs (101) for the selection and the time-setting of respective solenoid valves (102) in a watering cycle, and at least one additional period knob (104) for defining the frequency of activation of said solenoid valves (102) in said watering cycle.

2. Control unit according to claim 1, characterised in that it comprises a microprocessor (110) with system clock (111).

3. Control unit according to claim 1, characterised in that it controls at the beginning of cycle the opening of a main valve or “

master valve”

(112) positioned upstream of said solenoid valves (102).

4. Control unit according to claim 1, characterised in that it is supplied with direct current.

5. Control unit according to claim 1, characterised in that it is supplied with alternating current.

6. Control unit according to claim 1, characterised in that it is supplied with alternating current with safety battery in direct current.

7. Control unit according to claim 1, characterised in that said control push-buttons comprise a start push-button (106) and a delayed start push-button (108).

8. Control unit according to claim 7, characterised in that said delayed start push-button (108) allows a six hours delayed start of the programmed cycle.

9. Control unit according to claim 7, characterised in that the simultaneous operation of the start push-button (106) and of the delayed start push-button (108) allows the interruption of an operating cycle and the re-set of the same cycle.

10. Control unit according to claim 1, characterised in that said signallers of state comprise luminous LEDs (103) associated with each knob (101) controlling a respective solenoid valve (102), a start luminous LED (107) of an operating cycle, a luminous delayed start LED (109) and a battery state signaller (105).

11. Control unit according to claim 1, characterised in that each one of said selection and time-setting knobs (101) provides an OFF position which excludes the respective solenoid valve (102) from the watering cycle being set up.
