Thank you for your question. The Delta Addison 3-Setting Diverter T11892-RB is designed to control one extra installed showering unit. The Delta Addison 6-Setting T11992 is a diverter trim that is used when you have two extra features added to your tub/shower or shower combination. Paired with the R11000 rough-in valve, it will divert the water to your hand shower. By using a 6 position diverter and not having a second feature, it is physically possible to use the other notch as a "on/off" position.
