The knobs, starting on the left are the Infinite water level with RESET position, the Sudsmiser control for save or drain, the wash water temperatures, the rinse water temps and the agitation speeds. The spin speed was built into the cycles. I am not sure, but I think one of the lesser features on this machine was the elimination of the Cool setting in the wash temperature selections. On our Lady, the Delicate cycle had the gentle agitation speed built into the timer. You could not get normal agitation in the delicate cycle.
