Bit Logic, Weekly Timer, and Calendar Timer Application

You can change watering times as shown below in the examples to match the hours of sunlight.

Water at 4:00 from May to July
Water at 5:00 from August to October
Water at 6:00 from November to January
Water at 5:00 from February to April


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.

Benefit / Efficiency

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.
