i was worreid that it going to use more water than i have used historically. plus, lets face it, the behavior is a little transient, so it is hard for me to become used to the lack of pattern that i have been accustomed to experiencing.
for me, once i go over a certain usage, the municipality slams you will this huge price increase per 100 gallons of usage, which adds up very fast. put it to you this my, my neighbor used 1000 gallons more than i one month and had an additional $200 added to his bill for the month.
dont get me wrong, it is the greatest thing since sliced bread, but complete autonomy is hard to overcome when the habit of predictability has been reinforced for 7 years...the only thing that would change from my previous controller was that the system would NOT run when i thought it should (rain sensor).
even my wife whom controls the checkbook and is a practicing member of Judaism when looking at the checkbook was pretty nervous.
after a month we were both sold because we could identify times that the new system intelligently didnt run when we knew the old system would run.
it took about 2 months for our dialogue to evolve from, "is the system going to run tomorrow, it rained a few days ago, lets manually activate the rain sensory to keep it from running tomorrow" to "hey i see the system is not going to run tomorrow but i planted some annuals 2 days ago, can you schedule a run for the morning on zone 7"?
notice the subtle difference in expectation, are we about to waste versus lets reduce some savings for a moment.
it is completely psychological...it cant be quantified.
provide flow metering support so that i can reconcile the autonomous behavior with empirical data. maybe not for everybody, but for me, that would have gone a long way. basically, each evening, checking the gallons used would continue to build confidence and excitement instead of having to way for the water bill to show up...and checking the meter itself is not worth while.
dont pay attention to me, im somewhat of an outliar i think
