Sprinkler System Control


Bit Logic, Weekly Timer, and Calendar Timer Application: At these times, sprinkler valve 1 turns ON for 10 minutes. Next, sprinkler valve 2 turns ON for 10 minutes. Finally, sprinkler valve 3 turns ON for 10 minutes.


It is possible to automatically control the calendar timer and the weekly timer with a ZEN alone. Because individual wiring is not necessary, you can reduce the wiring time greatly.
