I have 2 Clack valves, one for a Iron/Sulfur Filter, and one for a Softner. Both have 15V power supplies but I noticed a 12V marking on the 4 button Sulfur board. The softner board is 5 buttons but voltage is not labeled at the power connector. How do I know what voltage this should board should be, and is there a problem using 15V on a 12V Clack board?
