I have a Hardie 4000 control box which is working fine. There are (4) watering stations which each have a possible (3) start time settings. Start time (1) is for 5:00 A.M., start time #2 is for 4:00 P.M. and Start Time #3 is OFF. What I would like to know is how to set Start Time #2 to OFF also. I have no manual for the unit. Can anyone help me out with this. Thanks Trinity
