Dave, as usual, is right. The attached image shows the wiring of the S24 switch and the wonderful quality of MB CD manuals. Seems like a lot of wires for a simple momentary switch. Such things are not my forte so I often have to eat crow. Pass the ketchup.
But the concept should work. Leave this switch behind the console and use another switch to send a switchable signal to the recirc switching valve downstream of the pushbutton unit. Anyone know how to wire it so there isn't a signal back to the pushbutton unit when when the override circuit is engaged?
