Question
Hi Matt.  I have my watering system set up to come on every odd day, this is OK.  It goes through the first 5 zones OK, but when the 6th zone comes on, #1 zone comes on again at the same time, then it will move to zone 7, and zone 2 comes on at the same time, zone 8 and 3 come on and so on.  It keeps cycling and does not turn off.  I have erased any prior programns and started over, but to no avail.  HELP

Answer
So sorry for my late response.
Under any programming I know of, the controller will not operate this way. It appears the controller has an internal short. It will need to be replaced.
I would check for warranty with  your contractor or manufacturer. Many of the new controllers have 3 or 5 year warranty.
