Thank you for your question! In order to adjust the temperature of the Delta Foundations Tub and Shower B114900C model, you would need to adjust the Rotational Limit Stop, that goes over the stem of the cartridge. I have outline a step by step process, below:
1. Please shut off your water, you shouldn't have to do this if you are not removing anything but the handle. 2. After removing your handle, you will see a brass stem, with a blue cap held on by a black o-ring. 3. Remove this o-ring. 4. After you remove the o-ring, you are now able to adjust your "RLS". All you have to do is lift it up just a little bit, rotate counter clockwise. Please keep in mind there is a limit on how far you can rotate this, if you rotate too far it will not attach properly. Also, please keep in mind if you rotate this all the way to the maximum, this can result in very hot water as this would be the maximum temperature off of your water heater. 5. Once you are done rotating your "RLS", please attach your o-ring and your handle. 6. Test the temperature, if you are still having issues please advise. Please feel free to call, email, or message us on social if there is anything else you need.
