How do I create a 3 day run once timer?

[AZMSGT]

I want to run my carbon on a 3 day timer. Is there a way to set a timer to run a switch on for 72hrs?

You can use the days of the week option for this purpose. Go to the TIMER settings page, select the days you want to run this timer.

For example, since the carbon reactor should run for only 3 days out of the week. You can select the 3 consecutive days to run the timer.

Click the NEW button, specify the ON-time and OFF-time for this timer, then save settings.
