I am switching over to a tankless system and will have my wax and rinse setting open one solenoid valve for cold water. How to I make sure my solenoid that allows wax to be drawn in doesn't open when the selector is set on rinse? I am picturing the current going to the cold water solenoid and sending a current to the wax system which will open the wax solenoid. How do I isolate that solenoid?
Thanks
