Older Clack WS1 - 4 button valve. Small display, not an EE board. The setting names are printed on the faceplate. I am trying to figure out how and what to change my volume x 1000 setting to.
We need a lot more information. What size is your system? Is it a softener? The old boards are fairly easy to program, can you post a picture of the valve?
