If you're speaking of the irrigation system.......ours is a Hunter 600i - here's the owner's manual and programming instructions for it:

You might have a different manufacturer/model - no way for me to know.
Do you have a way to contact one of your neighbors to see if they can tell you what system/controller model they have? Better chance that your system would be the same as theirs. Or does a neighbor/house watch person have access to your home? They could check it out.
