Good afternoon what are users of 520s setting the off timers at? Minutes off and minutes on. Thanks.

30 minutes off, 2 minutes on. Works perfect for me.

30 minutes off and 1m 47s on for our 520. I think my father in law was shooting for 2 minutes and came up a little short but it's been working great that way for decades.
