I am a newby and am, so far very pleased with the unit. I really want to use the daily flex schedule but have an issue with start up. When I create the new schedule, it wants to water each zone for about 40 minutes total. That will turn my yard to mush. I know this because I set my old controller to water manually one day, then got involved in something. 40 minutes or so later I remembered it was on and the yard was mush. Is there any way to start the daily flex schedule without the initial, overly heavy, watering? Or is there a way to manually change that first watering?
