I decided to play around with the Auto Shut Off feature today. My baseline flow is 0.7gpm. I popped off one head and calibrated to see what the reported flow was, and that was 1.3gpm. I then set my High-Flow Trigger to 145% (1.02gpm) and enabled the auto-shut off. The video shows the resulting shut off at about 30 seconds in. It takes a couple of minutes to empty out the line, as this is the lowest spot in my yard, so I sped up the video starting at the 1 minute mark.
For some reason the message on my phone says that the flow was 114% above the baseline, which is not correct since it is over 200%, but you can see that the function works! Also the calibration routine doesn’t work quite right. I get an error message after EVERY calibration, even though the calibration seems to successfully complete. The calibration shows completed in my history and the values are set accordingly in my zones. It is also odd that it shows the calibration is determined at the beginning of my 5 minute calibration cycle rather than the end. Regardless, it seems to be working !
