Program Pump to Run Based On Time Within The Hour

[JMarsh178]

Hello,

I'm trying to program a pump to run for 10 minutes at a time every hour but would like it based on the time within the hour. For example run every hour at the :15 :35 and :55 minute marks. I know I can set up OSC to specify on/intervals, but my concern is that in the event of PF or other interruption it would resume the OSC from whatever the minute mark was when the interruption was over.

Apologies if what I'm trying to explain isn't clear.

If the total number of minutes in your OSC is evenly dividable into 24 hours then the command will always start at midnight.

^this. OSC is predictable and always starts at the same time (mignight on that wierd date in 1970 that UTC began). As long as its on an interval that repeats the same way every day like hourly, every 3 hours, every 4 hours, every 12 hours, etc. It will always start the cycle at midnight.

You might be an engineer if...You have no life and can prove it mathematically.
