I think a lot of people don't realize that the solar sync sensor can automatically change the watering times that they set. Also, many irrigation technicians don't have a clue about how the system works, and they don't even use consistent regional settings throughout The Villages. Region 3 is for U.S. southern states, but I have seen various controllers set on Regions 2, 3, or 4. Also, they always seem to use the water adjust calibration setting of 10, when the manual says it can range from 1 to 10. The only way to really establish the proper calibration setting is to monitor the system over a period of time, something that technicians never do.
