My smart timer is not adjusting the times based on the weather. In the past, it would run longer or shorter based on the weather but now it is just doing standard runtime – everytime.
I have tried adjusting the MAD to 5% so the sprinkler runs daily. It will run daily at 33 mins total for 4 zones, the Standard Run Time.
I have tried adjusting the MAD to 10%, also so the sprinkler runs daily. It will run daily at 69 mins total, the STDRT.
It never changes, even at default settings, it runs the STDRT everytime. Just different intervals.
If I use the schedule adjustment feature, it will adjust the interval between the days but the runtime doesn’t change.
It seems like the timer is not calculating how long to run for it to refill. The daily weather is being completely disregarded it seems. It used to recacluate and adjust runtimes everynight I thought.Spread the love!September 12, 2018 at 2:21 pm #71817

@VTX531 It is more likely that the interval will change and not the actual run-time. However, I do see that your timer is now running for a bit longer now.
Also, the run time can be adjusted in the Zones page. Tap your zone, then tap smart details, then tap watering adjustment. You will see two sliders, one for run time and the other for watering interval.Spread the love!September 15, 2018 at 3:00 pm #71848
Is that a new change that the smart timer only changes the interval?
I am 100% sure that previously, whenever it got down to the refill point, the time was adjusted to fill back to 100% based on the application rate.
And I thought that was a requirement of having the EPA water sense label.
Something is wrong the the programming, maybe a recent change, if the timer is not filling back to 100% when it goes below the refill point.Spread the love!September 20, 2018 at 5:33 pm #71903Josh WheelerKeymaster
I asked the developer responsible for smart watering to look into your timer, here’s the gist of his explanation.
Earlier in the season your ET (water consumption/evaporation) was so high that the system had to water before a full depletion level was reached or it would have a negative affect on the plants and it would put the zone into such a deficit that it would not be able to catch up in a short enough time.
Now that things are cooling off a bit the system is able to let it get to a regular depletion level and it has adjusted for that, according to what he told me. This would also explain why you don’t see the rapid changes you saw before, there’s less volatility in the we weather and there will be less change in the programs too.
Also, he noticed that you did perform a catch cup test for your zones and that the application rate varied on one of the zones, it was almost twice as much as the others, this would explain why one (sorry, I don’t recall the zone) zone will be watering for less time than the others.
He did reassure me that your system is and has adjusted for the current conditions based on the catch cup inputs for application rate and current ET values.
Hope this helps, it’s an oversimplification but that’s the level I understand it on too but I hope it helps.
