Hi there Chris,
Thank you for your question. When installing the R22000 Integrated Rough-In valve, the plug should be soldered to the right outlet port of the in wall valve, for the Delta Traditional 17 Series 3-Setting Integrated Trim T27897 to function with the indicate handle rotation. If the left port of the valve was actually capped off, you can purchase just the 6 setting diverter cartridge, RP51919, so that all of your setting will work with your existing trim. There will be a few dead spot with this cartridge installed.
