In the left hand corner (upwards) there is a blinking icon on the controller. It will not allow me to do a manual watering. I can set it and it will display the zone and time set, however no water comes out. How do I get rid of this blinking icon?

We had a multiple short power outages yesterday. The Hydro-Rain HRC 400 WI-FI Controller shows I have sprinkler valves that should be running either manually or by program and nothing turns on. I plug and unplugged the unit, nothing changes. It was near 100 degrees here so I need help. Meridian, Idaho
