I had an Irritrol Junior Max controller for my sprinkler system that recently went on the fritz and was told that it wasn't repairable. I bought a Rainbird ESP 6 TM and thought I would try and replace it myself but of course with little knowledge on the subject I have run into a problem. the Junior Max had two spots labeled "C" for what I understand are the Common white wires. My problem is that the Rainbird only has one marked "C" so I don't know where to hook up the second white wire. The only spot left is the one marked "MC" for Master Valve. The other problem is that when I try to run it manually the fuse keeps blowing.
Have I bought the wrong type of controller?
Many thanks for any help you can give.
