This is a common question.
And the answer is usually very simple. Generally speaking this happens when more than one start time is set.
Unless there is a watering exemption in place you are only allowed to water once a day which means you only need one start time.
Often people get ‘start times’ and ‘run times’ mixed up. So get this :
YOU ONLY NEED 1 START TIME!
Most errors are made when people set 5.00am as a start time, then 5.15, 5.30 and so on.
So when you set your controller make note of which function you are operating in the dial and just set the one start time.
If you get stuck then just give me a call!
