I replaced my Rain bird Controller with a rainmachine, The Rain bird had 1 C, 1 MV and six zones wired.
After reading the instructions I moved each wire, one at a time, between the controllers. On the rainmachine I have 1 C, Zone 1 is the master valve and use zones 2-7. I was able to set up the zones, with zone 1 being the master valve. When I tested manual watering my last zone came on when all other zones were run. I disabled the zone and the same problem occurred. I removed the wire from zone 7 and the same problem occurs. I finally used shut off the flow control valve to that zone so as not to waste water.
I watered each zone right before I replaced the controller so I know this isn't a problem that I had before I made the switch. I have been doing some research and some suggest this happens when someone configures a Master Valve when they do not actually have one. However, I know I have one because I looked. I am not sure what to do here because the wiring is very straight forward on both systems.
