This document provides instructions for programming the timer of an Aquadue Duplo irrigation controller. It explains how to open the timer unit and insert a 9V battery. Pressing buttons allows the user to set the current time. Programming is managed through pages that can be viewed and modified by pressing buttons. The user can program watering schedules for two lines (A and B) by pressing buttons to select start times, open and close times for up to 6 programs per line.

Pressing the FORWARD key button, the display will move through to weekly programming. With weekly programming, the user can select in which
days watering is required. This programming function is the same for both lines. Warning: day (1) coincides with the day on which the first watering
cycle is set. Example: first programme set on Thursday = day (1). Warning: day (1) provides the reference point for weekly programming. Example: If
Thursday = day (1) and the intention is to skip watering on Friday, the day to deselect is day (2). To omit one day of the week, position the cursor of
the display under the number of the day in question, using the FORWARD/BACK key buttons. Press ENTER and the number will disappear.
