Have a customer that has a Hunter XC. Has been running everyday and she wants it to only water Mon., Wed., and Fri. Set these days to on and the others to off and she says it is still running every day. Tried to set it to odd days and still every day it runs. Does this thing have a preset program that I am not seeing, the dial does not show preset programs. And before it is mentioned she seems to have "misplaced" the instruction manual.
