Question
Why does a No AC sign show up on the screen? The sprinkler system is not going on automatic anymore.
Thanks

Answer
Hey Cheryl, the No AC sign means that the controller is not receiving power. Check and make sure the circuit breaker to the controller is turned on. If you are geting power to the controller, and you are still getting this message, then the controller needs to be repaired or replaced. Good luck and have a great day.
