Rain Bird ISA 304 Controller
My home came with discontinued Rainbird ISA 304 controller and without a manual. I am unable to get the controller to work in automatic mode. Using instructions for an ISA 408, which I found on the Rainbird web site, I have been able to set the date/time and program the controller using one of the Pre-set Schedules. Unlike the 408 which has an Auto/Run function, the 304 has in it's place a System On function. Placing the selector on System On, the controller does not turn on at the programmed time or interval. I checked my program input by testing it in the Manual mode, so I know it is correctly programmed.
