Why does my timer say OF…?

Question: You just repaired my rain dial RD600 two weeks ago, reinstalled today, flashed 0F9, did a reset now flashing 0F1 alternating with the time. Any ideas?



Hi David,  That indicates that the controller is turned off for 9 days; it’s a rain delay feature.  A RainDial button probably just got pressed accidentally while programming. It’s a handy feature to delay watering if it rains … you can read about it in the manual: http://raindialdoctor.com/wp-content/uploads/2013/07/Irritrol_Rain_Dial_2007_manual.pdf

See page 24

Why is this flashing happening?

The number indicates the number of days to not follow any schedule (you would set this if it rained).  To get rid of the rain delay feature, follow the steps below and change the delay back to 0.
see the following.  (Important: Make sure to slide the switch to Run again when you’re done or everything will stay off).

How to I turn set or turn off the RD 600 series rain delay feature?

The Rain Delay enables the Rain Dial to suspend all automatic watering activity from 1 to 9 days.
  1. Place the Function switch in the OFF position.
  2. Press the +/- button to set 1 to 9 delay days (OF 1 – OF 9). (when it’s shows the current time, the delay is off)
  3. Place the Function switch in the Run position.
When delays are active, the display will flash, alternating between the current time and the number of delay days remaining. The delay day number will decrease each day until watering automatically resumes at the end of the selected delay period. Note:

To disable RD 600 series Rain Delay feature

At any time you can return the controller to active mode, repeat steps 1 and 2 to decrease the Rain Delay till it just shows the time, then the delay is off.
There’s an alternate way to set this delay feature shown below, but I would use the steps above instead.
  1. Place the Function switch in the Set Programs position.
  2. Turn the Dial to the Skip Days – Special Functions position.
  3. Press the Manual button (repeatedly) to display rd0 (Rain Delay = 0 days).   If it says rd2 or another number, that number is the number of delay days currently set.
  4. Press the / buttons to select a Rain Delay period of 1 to 9 days or 0 to turn off the Rain Delay feature.
  5. Return the Dial to the Current Time position.
  6. Return the Function switch to the Run position.
