I just moved in to a new house where the previous owner had a gen 1 installed . I was able to blink up and log in to set up zones and that . But my sprinklers run on what I think is the old owners schedule. I have it set to run at 10pm , but the system starts at 205 am . I have it set to run for a total of 138 mins but it is running 155 mins . Am I missing something ?
