Question
I have an irrigation system with a JH Hardt 15 station controller.  The controller isn't working.  I can't fond a JH Hardy website?

Answer
Hi,

I believe you are looking for "James Hardie Irrigation" company. You may find the controller you are looking for under "Toro Irrigation", "controllers", "custom command" I believe that maybe the controller you have. Toro Company bought Hardie Irrigation a few years ago.
If you need any help getting your controller to work, feel free to reply back.
