Explain - Carry over water deficit to next schedule
My firmware is 4.0.1115. I have a Touch HD-12 model.
In the Web App under Restrictions, I see an option for "Carry over water deficit to next schedule" - "Day and rain restrictions will carry skipped irrigation to next schedule if needed."
I don't see any details in the Knowledge Base about this setting. Could you please explain a bit more what this setting does? Does it mean if I set a zone to water 20 minutes every day, but I put in a restriction to NOT water on a Tuesday, does that mean on Wednesday it will now water 40 minutes? What does the "if needed" mean? How does it determine if the carry-over is "needed"?
Is the danger in NOT using this option that if, for example, my yard needs 20 minutes a day, I skip a Tuesday (0 minutes), then on Wednesday, only 20 minutes is programmed to run, that my yard actually needs more like 30 minutes (because it got 0 minutes on Tuesday), that I am now not giving the yard enough water?
Could the yard be overwatered if I turn this setting on?
And how is this different from the Minimum Rollover Threshold? Can I use the Minimum Rollover Threshold together with the Carry Over Water Deficit to Next Schedule option?
Just trying to better understand this setting.
On my Pro-16 running the latest beta (4.0.1131) it is shown under restrictions.
That also fixed the rain sensor issue in that the settings were reversed compared to what they stated, so the system always thought water was detected. I know this as I had to make the settings the opposite of what it said; when the new firmware was installed I got an alert that the rain sensor detected rain. Which I knew was not the case, so I had to go and change the settings back to what they should have been.
I would also like to know how exactly this works. Under the weather setting there is an option to correct future watering cycles based upon actual past rainfall (I have a weather station on my property). This seems to be a similar setting so I would like to know how these two settings work in tandem with each other.
Think we described this in the applications in the mean time but for completeness I add the explanation here too:
Carry Over allows to add the missing irrigation (water quantity) due to a restriction to the next irrigation cycle. Without this RainMachine will not take into account what was supposed to irrigate during a day or rain restriction will just balance based on:
1. weather changes between the moment of the irrigation and newer data.
2. amount of water in soil
With this option enable RainMachine will recalculate the water needed for the restricted day based on latest weather updates and add (if any) it to the next irrigation cycle.
