Understanding the RD600 Irritrol Skip Days feature

When I set the skip day number to 1 – does that mean it skips every other day?



Hi Bill,

The Irritrol RainDial RD600 Skip days feature is often misunderstood and difficult to understand, so thanks for the question. I like to think of the skip days feature like a daily incriminating counter that starts at 1 and goes to the number you specify and then repeats. E.g., for a skip days setting of 3, it goes like this: 1,2,3,1,2,3,1,2,3. When the counter matches the number, the watering schedule will run.

Instead of ‘skip days’, think of it as ‘water every # days.’
So if it’s 2, it waters every 2nd day, which is every other day: 1,2,1,2. If you set it to ‘1’, it waters every 1 day, which is ‘every day.’

Although I’ve answered your question, one may ask:  How do I know what today is in the sequence of days?    You determine that by putting the dial on ‘Today.’  It will show you the current number in the sequence.  You can also change the number of ‘today’ by pressing the +- buttons when in programming mode.

E.g., if you have skip days set for 3 and you want it to water tomorrow, set ‘today’ to ‘2’.

I hope this helped.

    • Hi Scott,

      When using skip days, the individual days should show you ” — ” and not have on/off as a choice. Hopefully you’re seeing that 🙂
