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.

Connecting Electrical Power Once your HRC 400 Controller is plugged into the power source, it will automatically look to pair with your smart device. In the top left corner of the controller display the Wi-Fi icon will begin a graduated blinking sequence. This indicates that your Controller is ready to pair with a smart device.

Program Button (ABCD) Your sprinkler controller provides the flexibility of using 4 independent programs (A,B,C,D). A program is where you store all of your sprinkler settings. It consists of a group of valves set to specific start times and run times. Multiple programs allow you to run different valves on different days with different run times.
Start Time This is the time of day that your programmed watering starts, the first zone will begin watering at the 1st start time. You can set up to 4 start times. When a start time is set before the previous program has completed, that start time will be delayed, and will start upon completion of the previous program.
