Question
Hi, i have a james hardie irrigation system using a HHA-11272 board. The problem is that one of my sprinkler stations does not come on while the others work fine in manual. when they are on a set time to go on nothing works. I have checked that i am getting power to the board and all stations except the one come on when turned on manually.  do you know what the problem could be, thanks.

Answer
First, check all the wiring connections both at the controller and at the valves.  Make sure the connections are sound and waterproof.  Also make sure the flow control for the valve is opened about halfway.  Check your irrigation program, all stations need to have watering time programmed for them to run.  Also make sure you have a start time and water days programmed.  Also, try resetting the controller by disconnecting the power and battery back-up for about 5 minutes, then reconnect and reprogram.  If this doesnt help, consider replacing the controller.
