I’ve used a variety of delay times from 3 to 30 hours. Most recently I specified 6 hours rain delay and when I checked an hour later, the status of “Suppressed by rain delay” had reverted to “Off” as shown in the attachment below.
Perhaps there should be a clear explanation on exactly how the Rain Sense/Rain Delay function works. From what I’ve seen is that while the Rain Sense input is active then it prevents any program from running. If you now set a 6H Rain Delay then this value counts down from 6 to 0 ONLY while the Rain Sense input is active. As soon as it ‘dries out’ then the 6H delay also cancels and the stations start to run again. I would have thought that the countdown would continue and only after 6H would stations be allowed to run again. That said, if it triggers before the Rain Delay timer expires it should probably reset back to the saved Rain Delay timer of 6H, right? OR I have it completely wrong 🙂
